Ni Chi Le Ma?This popular Chinese greeting means “Have you had your meal?” and is usedin much the same was as “How are you?”. It reflects the special concern forfood that is typical of many Asian cultures. Skipping dinner might be possi-ble in western cultures, but not in China. It is essential to successful businessto understand these cultural differences .When one is “closer to the customer”,it becomes easier to understand cultural differences and respond to the cus-tomer’s needs. As part of our “closer to the customer” reorganization, wherewe are strengthening our local resources, providing faster service and to im-prove communication efficiency. diminishing cultural misunderstandings.

Economic growth has continued in China despite the SARS epidemic. In2002, paper consumption overtook that of Japan, increasing by 18% to 43.3million tons. Consumption per capita, 33 kg, is still far behind that of indus-trialized countries. In analyzing output, we should separate the high qualityproducts made with western technology from the lower quality products madewith older technology. For example, 70% of newsprint output is high quali-ty, whereas 70% of uncoated wood-free output is low quality. In any case, thedemand for new pulp and paper lines is big. Our challenge is not only to de-liver new machines, but also to arrange technology and service support for ex-isting, older modern machines.

Metso Paper ChinaMetso Paper first set up a representative office in China in 1992. Now, in re-sponse to the rapid growth of the Chinese market, we have undertaken a ma-jor reorganization. On June 18, 2003 we established Metso Paper (China) Co.,Ltd. to accompany our new Service Center in Wuxi city, and two branch of-fices in Beijing and Shanghai. Together with the Valmet-Xian joint venture, thenew company will serve Chinese customers more efficiently and competitively.

Asian cultures have usually been very price-oriented, with the investmentprice being the defining factor. But now customers are beginning to under-stand the importance of total costs of whole life span of investment; the start-up curve and total running costs, etc, as we have seen in the recent NanpingPaper start-up. Competition is becoming harder in China and final quality isessential to success. This concerns not only new machines, but also older ma-chines where the need for constant service and improvements is being recog-nized. This is the key to the Metso Future Care concept which we are alsolaunching in China. We aim to develop as a knowledge-based company, fo-cusing on improving our customers’ productivity and competitiveness.

Metso Paper (China) can already provide Chinese and global pulp and paper customers with the same quality of machinery and equipment and withthe same support and after-sales services as are provided by Metso Paper, Inc.all over the world – in short, Metso-quality products and services, with a lo-cal Chinese approach. �D

A papermaking line employs a wide range of dedicated machinery and control systems. By the time a par-ent reel is ready for “take-off” at the reeler, it enters the paper mill finishing room to be processed again. Apaper mill finishing room typically includes a range of activities for the further handling and post process-ing of parent reels. The need to achieve a competitive edge is a demanding task for every papermaker. MetsoPaper’s OptiStream solution offers an effective tool for this particular field of papermaking.

Who would not dream of finishing operations with a well-working, space saving layout

OptiStream◗ B Y P E R T T I O J A L A A fresh solution for the paper mill finishing room

The paper web on each parent reel is transformed into roll form, partof which is eventually processed further to sheet form, with it thentransferred through the paper mill’s internal conveyor systems to fi-nally reach vehicles for transportation away from the mill. It is a verychallenging logistical task to handle parent reels, paper rolls and sheetpallets, including all the necessary trimming, identifications, mark-ings, sortings, warehousing etc., and also including secondary oper-ations like ensuring the correctcores are at the winders and theright packaging materials are atthe wrapping machine. The start-ing point for logistics in theOptiStream solution is the paperproperty profile of a single par-ent reel, on which the final trim-ming decision at the winder isbased. The end point can be seento be the reel ending up on thecorrect truckload in the shippingarea of the paper mill’s ware-house.

Traditional problems – How about a fresh thought?Traditionally, each vendor that pro-vides machinery and systems forfinishing rooms has their own ap-proach to machinery and processdevelopment. When the finishingroom is furnished with machineryfrom multiple vendors, there is typ-ically some compromise in the fi-nal layout and in the final process.Most of the issues relate to the widevariety of software, control systemsand hardware, and finally add upto a less automated process, whichis more vulnerable to errors. Somecommon features of multi-vendordelivery are:

◗ Many machines are delivered ascomponents, without takingcare of the whole process

◗ Slow development of startupcurve

◗ Several control systemscomplicate operators’ work andmaintenance

◗ Finally project ends up with:

– an inoperative finishing roomlay-out using excessive space

– a less automated process thantargeted that is morevulnerable to errors

Not so long ago, paper ma-chines were also delivered by mul-tiple suppliers. At that time a millchoose a different supplier for theheadbox, former, press, and dry-ing sections. Today it is usual forone supplier to deliver the wholepaper machine. Therefore itwould also be beneficial to selectthis type of single supplier ap-proach for the finishing room aswell. Such an approach will offera lot of potential to develop boththe efficiency and quality of fin-ishing room operations. This iswhat the OptiStream solution isall about.

The OptiStream solution – What is it all about?The OptiStream solution can havea wide range of options in the de-livery scope, however it typicallycovers several finishing room sec-tions. The full scope of the Opti-Stream solution includes the fol-lowing; engineering, systems, andmachinery in their fully automaticform, all well integrated together:

◗ Layout and conceptengineering for the finishingroom

◗ Parent reel and reel spoolhandling

◗ Winders and a rewinder,including any of the followingrequired:

– Trim removal, dust removaland moisturizing

– Pulpers

– Core handling

– Broke handling

– Roll handling at the winderdeck

◗ Roll conveyor system includingrequired roll sorting

◗ Roll packaging machines

◗ Roll splitter

◗ Intermediate roll storage andcustomer roll warehouse

◗ Vehicle loading, e.g. truck, train,or container loading

◗ Manufacturing ExecutionSystem (MES) for the wholefinishing room

continued overleaf…

Such things as installation,startup, training, maintenance,future expansion, and other futureneeds are also naturally taken careof in the OptiStream solution.

One of the leading ideas behindthe OptiStream process layout isto locate one operator team work-ing in a single control room. Theentire finishing room machineryfrom parent reel handling to au-tomatic customer roll warehouseis controlled from this central con-trol room. Each finishing equip-ment section is located close to thecontrol room. The equipment isdesigned to be efficient, to mini-mize roll handling movements,and to save space. The benefits ofhaving one operator team and thisspace saving layout are:

◗ Optimized labor resources

◗ Minimization of roll damage

◗ Increased safety

◗ Greater operator motivation

The manual work load is min-imized and at the same time op-erational quality and efficiency isincreased by using several MetsoPaper developed and launchednew machines and features:

◗ In-Line parent reeltransportation

◗ Continuous winding

◗ Continuous roll handling

◗ StreamLine Pro – fullyautomatic high capacity roll wrapping machine

As manual tasks are reducedsignificantly, the operator’s role inthe process changes from beingtask-oriented to process supervi-sion. Paper mill internal resourcerotation is easier, and the finish-ing room is more cost efficient.

Parent reel handling – Full automation in sightThe parent reel transportationfrom paper machine reeler wind-up to winder unwind handles reelsweighing up to 140 metric tons. Intoday’s modern paper mills this reelflow is typically semi-automated.

Metso Paper has recently re-designed reel rails to replace theclassic sloping reel rails with newhorizontal rails. Massive reels aretransported with the help of newelectrically driven transfer ele-ments. Gravity is no longer usedin reel transfer. The parent reelsmove smoothly on the rails with-out “waddling” from side to side.The maintenance frequency of thetransfer rail and spool bearinghousing is substantially decreased.This new system is reliable, easyto install and also makes it possi-ble to move reels upstream in thecase of web breaks at the winder.A fully automated OptiCart par-ent reel cart will move the reels inmachine cross direction to the off-line winder, or to intermediate reelstorage places. Empty reel spoolscan be transported back to the reel-er, utilizing most of the same equip-ment. So there are now elementsavailable for full automation.

Winders - Making the most of Winding ForceIncreased roll dimensions on ro-togravure and offset production,as well as on coated paper gradeswith their mark sensitive surface,often represent a challenge to rollfinishing systems. The OptiStreamsolution has efficient tools to han-dle this kind of paper production.Metso Paper’s WinRoll andWinBelt winders are a reliable so-lution for all high capacity andhigh quality paper production.Both these winders utilizeWinding Force – a unique wind-ing tool. This tool helps avoidmottling and all other problemscaused by high nip loads. This isthe case in high quality WFC,LWC, SC and newsprint produc-tion, for example. By usingWinding Force as a control toolto reduce excessive nip loads,these winders can produce tightrolls of excellent quality. J-line,which indicates layer-to-layer slip-page, is brought practically to ze-ro. WinBelt’s efficiency and rollquality has been proven in morethan 100 deliveries for the mostdemanding paper and boardgrades.

Roll stream – Smoothly running to their correct destinationsEach time a new set of rolls en-ters the roll handling system at thewinder deck, rolls are separatedand furnished with a barcode. Inmost cases the winder operatorapplies the code carrier barcodetags manually. Such an operationis unnecessary with the OptiStreamsolution as it offers an integratedfully automatic winder deck to de-crease the number of manualtasks, and to increase productivi-ty and operator safety. Startingfrom the cushion stop line that in-stantly settles rolls on the con-veyor, continuing with set sepa-ration and proceeding to the on-line direct bar-coding station andfurther on to logistical control: thewinder operator need only moni-tor the flow and replenish con-sumables.

Depending on the paper gradeproduced and on layout issues, theOptiStream solution employs acombination of SmartTouch rollhandling equipment. The selectedcombination is tailored to meetcurrent requirements and to fore-cast future needs. The range ofequipment available is broad. This

new approach ensures that eachcomponent works seamlessly to-gether with other sections and ma-chines in the process.

The roll wrapping applicationcan range from fully robotic tomanual, depending on capacityand mills resoursing policy. MetsoPaper’s extensive expertise in rollwrapping will provide the besttype of wrapping solution to pro-tect rolls during transportationuntil they are unwrapped forprinting or converting.

One of the latest wrapping in-novations is the StreamLine Pro,a robotic multi-station wrappingmachine, which offers the highestroll capacity on the market – upto 200 rolls per hour. Operatingwithin an OptiStream process en-vironment, StreamLine Pro pro-vides a perfect fit for cases wheremultiple papermaking lines pro-duce a high roll count and onlyone centralized wrapping ma-chine with a reduced number ofoperators is needed.

Next to wrapping is a convey-or system that forwards the rollflow, sorting when necessary, tointernal addresses, intermediatestorage or the customer roll ware-house. In some cases crane stor-age has been used as intermediatestorage for rolls proceeding tosheet cutting. An AS/AR (auto-mated storage and retrieval) sys-tem - a rack style warehouse - isused for customer rolls proceed-ing to external transportation.The OptiStream solution typical-ly includes seamless and fluentconnections to several storage,

warehouse and vehicle loading al-ternatives, as required in the in-dividual project.

Downsizing paper wastePaper waste in the finishing room canbe divided into three categories:

◗ Trim waste

◗ Roll and reel damage waste

◗ Machine direction waste

Thanks to the OptiStream so-lution, the situation for all of thesecategories is improved. More ac-curate parent reel transportationon horizontal rails eliminates reeldamage, while crane assisted han-dling is no longer required. Reelspool damage, such as bent jour-nals, is also eliminated. When aparent reel matching the combinedlength of the sets can be producedat the reel, a lot of bottom wastecan be reduced. Due to variationsin the paper making process thethickness of the paper varies at thewinder. Metso’s recently intro-duced PC-based WindControl op-tion offers a tool for optimizingreel sizes and further minimizingmachine direction waste.

Trim optimization (or deck-ling) for minimizing web widthwaste at the winding process iscommon in the industry, and pro-vides an effective way to minimizeoverall waste in the process.Today it is also possible to mini-mize trim waste on the variousmachines standing next to thewinder, such as rewinders, coaters,extruders and sheet cutters.Potential savings are generally

available if other finishing ma-chines can be trim-optimized to-gether with the winder. Re-trim-ming also has a huge potential ef-fect on efficiency and profitabili-ty. At a winder level, re-opti-mization efficiently takes into ac-count rejects, customer-specificquality specifications, and quan-tity tolerances.

The winder unwind butt-jointsplicer, which is a fully automaticsplicing unit, makes excellent qual-ity splices in 4 minutes automati-cally. Splices can be made anywhereon the reel whether it’s an almostfull reel or a near empty spool.Short reel ends, which were earlierrouted to the pulper, can now bespliced to sellable production.

The key to an optimally func-tioning finishing line lies in a well-planned space saving layout.When the winders, wrapping ma-chine and automatic warehouseare located close to each other, thenumber of roll handling equip-ment components can be mini-mized. This will not only reduceinvestment costs, but will alsominimize handling-induced rolldefects. The less paper rolls arehandled before the warehouse, theless opportunity there is for rolldamage. The smooth flow of au-tomated handling in the customerroll warehouse causes less rolldamage than manual handling.

Manufacturing Execution System – Sounds like automation?One essential part of the Opti-Stream solution is the integratedautomation package that ties bitsand pieces together. Metso Auto-mation’s Manufacturing Execu-tion System package, calledmetsoDNA MES, is specially de-signed for paper mills, includingmodules for the following tasks:

◗ Order processing,Shipping, and Invoicing

◗ Warehouse Management

◗ Production Planning (PP)

◗ Production Tracking (PT)

◗ Process Management (PM)

◗ Quality Management (QM)

◗ Cost Management (CM)

Essentials within the Opti-Stream solution, Production Plan-ning and Production Tracking ef-ficiently enable mills to improvetheir finishing room process. TheProduction Planning module in-cludes production scheduling andtrim optimization. Productionscheduling involves the creation ofa plan that achieves customer ser-vice objectives with maximumproduction efficiency. Trim opti-mization minimizes trim waste,knife and pattern changes and or-der spread, while maximizing ma-chine utilization and value perhour. Trim optimization also in-cludes a re-trimming option.

The Production Tracking mod-ule interacts with finishing roomequipment and controls the ma-terial flow from the paper ma-chine to warehouse and shipping.Production Tracking also includesa Reel Length Optimizer to pro-duce reels of an optimal length forthe winder, in order to reduce bot-tom waste.

OptiStream – A finishing dreamWho would not dream of finish-ing operations with a well-work-ing, space saving layout; fully au-tomated machines and intelligentinformation management all seam-lessly integrated together?

And who would not dream ofone united operations team, ef-fortlessly managing all the finish-ing operations in a safe and mean-ingful work environment, easilyreaching increased efficiency andquality targets in paper mill pro-duction and operation?

Metso Paper’s OptiStream so-lution will make your dreamscome true! �

GradeMatic- next generation compact coating color preparation process ◗ B Y J O H N B E R G M A N

The coating color preparation process has traditionally been regarded as asub-process of coating. In the sense of process integration the coating col-or kitchen has been a separate unit which produces the needed amount ofcoating color with the desired specifications. When regarding off-line coat-ing this process setup and integration has been sufficient in order to ensurehigh quality coating with sufficient time efficiency. The critical issue in coat-ing preparation has been 100% availability without any major disturbancesin quality: “No news from the coating kitchen is good news”. When tar-geting the ultimate efficiency in on-line concepts this is simply not enough.

During recent years the paper in-dustry has been actively introducedto all on-line papermaking con-cepts. High efficiency on-line pa-permaking lines have been put in-to production, for example UPM-Kymmene, Augsburg PM 3 andCartiere Burgo, Verzuolo PM 9.During the start-up and operationof these lines a significant amountof information has been gainedconcerning total line efficiency,on-line quality control and on-linegrade changes. The experienceshave indicated that the coating col-or kitchen should perhaps not on-ly be regarded as a separate pro-duction unit. The experiences ac-tually showed that coating colorpreparation should be closely in-tegrated to the coating operationsin the papermaking line.

A Metso Paper-wide develop-ment project was started in 2001.The target of this project was tointroduce an all on-line paper-making concept to the market.The new papermaking conceptwas presented to the market inFinland in June 2003. One of theenabling technologies of the pro-ject was the compact continuouscoating color preparation process,the GradeMatic.

Process descriptionThe main targets in the develop-ment of the GradeMatic coatingpreparation process were all on-line operation (continuous prepa-ration process), fast grade changes,reduced investment costs and highquality coating color (on-linequality tracking and control). Inorder to fulfill these targets it wasinevitable that a completely newprocess had to be designed. Theprocess development started withan analysis of the basic phenom-ena of coating color preparation.Among other things, the additionorder of the coating color com-ponents1 and the recyclability ofthe coating color were investi-gated.

“No news from the coating kitchen is good news”

GradeMatic coating color preparation unit.

The GradeMatic coating prepa-ration process starts with the fil-tration of all raw materials. Thefiltration method depends on theraw material in question; self-cleaning pressure filters and bagfilters are used in most cases.

The dosing and metering ofraw materials is done with directfeeding lines from the storagetanks to the mixing zone of theGradeMatic unit. The metering ofraw materials is done with highaccuracy mass flow meters ormagnetic flow meters.

The coating color componentsare mixed together in a controlledaddition order. The research madeduring the project showed that theaddition order significantly influ-ences the final coating color prop-erties, even with basic LWC off-set formulations.

When all the components havebeen pre-mixed together it is es-sential to disperse the mixture ina high shear OptiMixer DS. TheOptiMixer DS mixer is a rotor-stator unit equipped with equiva-lent torque control. This meansthat the coating color will bemixed just the right way even ifthe production capacity or coat-ing color properties are changed.

The whole mixing process in theGradeMatic unit is pressurized. Inpractice this means that no air en-trainment in the final coating col-or mixture is possible. This is a sig-nificant advantage compared tocurrent state-of-the-art technology.

The coating color quality iscontinuously monitored withColorMat on-line measurementtechnology. This enables directcontrol of the quality even duringgrade changes or when changingraw materials.

Finally, one significant part ofthe GradeMatic process is the au-tomation and control technology.The latest fieldbus technology hasbeen utilized in order to maximizethe diagnostics, operational andself-maintenance capabilities of

the process. The control systemFlexCom dB has been specifical-ly designed to meet the require-ments of the continuous coatingpreparation process. FlexCom dBincludes raw material and storagemanagement, formulation con-trol and optimization, instrumentand process diagnostics, and pro-duction and quality reporting2.

Production scale experiencesThe first full scale GradeMaticcoating preparation process wasdelivered to MD Papier, AlbbruckPM 5 in Germany. The GradeMaticprocess was part of the OptiSpraydelivery made in the beginning of2003.

The erection and start-up of theGradeMatic process was a suc-cess, with the process started twoweeks ahead of schedule in earlyJanuary 2003.

In order to verify the actual gradechange time on the GradeMatic, aseries of trials were made prior tothe coater start at the end ofJanuary. One significant result ofthese trials was the verification ofthe average grade change time.The results of these trials areshown in figure 2 below. Each ofthe trial points shows a gradechange. In this case a grade changemeans a change in capacity, achange in dry solids or a changein a component dosing amount.

that it is approximately 20–30times faster.

The coating color quality wasalso checked carefully during thepre-trials. The coating color qual-ity was determined to be good atall trial points. The binder sup-plier and MD Papier, Albbruckmade the evaluation.

Benefits of GradeMaticThe GradeMatic continuous coat-ing preparation process has manysignificant advantages: reduced in-vestment cost, reduced variablecosts (chemicals, fresh water, ef-fluent and energy) and the coatingcolor grade change capabilities.

is limited. The GradeMaticprocess can also be installed in asingle floor configuration, mean-ing a 15–25% saving in totalbuilding costs.

Experiences from MD Papier,Albbruck have also been very pos-itive. This is how the mills tech-nical director Lars-Hugo Olssondescribed his experience with theGradeMatic process: “Naturallywe’re still (March 2003) in thestarting phase, but generallyspeaking it has worked well.We’re now optimizing the differ-ent stages of production. I wouldsay that the coating color prepa-ration has worked well.”

SummaryThe newly presented GradeMaticcoating preparation process can beutilized with great benefits for coat-ing preparation in on-line paper-making processes and rebuilds. Thetotal efficiency of the process dur-ing grade changes is significantlyhigher than with a batch process.In addition, the diagnostics and theprocess support features make theGradeMatic easy to operate andmaintain. The GradeMatic is one ofthe enabling technologies for an allon-line integrated papermakingprocess with high efficiency. ■

TOWARDSCLOSEDWATER

CYCLES ◗ B Y M A R K K U H U H TA M Ä K I

Metso Paper is developing moreenvironmentally friendly paper-making processes. Chemical and

water management know-how andsystems deliveries are an elemental

part of this development.

Conventional solutions do notprovide the optimal answer formills where water consumption isbeing reduced and increased ma-chine speeds require a cleaner wa-ter system.

At Metso Paper’s TechnologyDays 2003 we introduced a newcost-effective papermaking solu-tion for coated woodcontainingprinting papers. The launched so-lution includes the use of kidneysat mechanical pulping, DIP-linesand paper machines as well as theintegration of the effluent treat-ment as part of the mill watermanagement concept.

New solutions for water recyclingConventional mill water treat-ment includes the removal ofsolids coming from screens, clean-ers and other fiber purificationprocesses to the effluent, and theremoval of excess white water.When water consumption is re-duced, the soluble and colloidalcomponents are removed withsmaller water volumes – which al-so means higher concentrations inthe mill water system if there areno internal kidneys. The Save-Allsystems also retain the detrimen-tal colloidal material to the fiberfraction. Internal water purifica-tion is a sustainable way to con-trol these impurities.

The amount of dissolved andcolloidal impurities in mill watersystems is also increasing due tothe following tendencies:

◗ Use of cheaper wood materialwith higher extractiveconcentrations

◗ Increased use of recycledpapers and a decrease inrecycled paper quality

◗ Increased use of paper makingchemicals

◗ Higher converting of papers –more glues, inks, plastics andother impurities in recycledfiber

It is usually clear filtrate that isdischarged from the mill. However,in order to keep the colloidal im-purity concentrations at a reason-able level, dirtier water fractions,

for example from presses, shouldbe discharged or treated.

The new solutions include, forexample, the removal of wood ex-tractives during chemical and me-chanical pulping, the improved re-moval of colloidal and soluble im-purities at recycled fiber mills, andincreasing PM runnability apply-ing membrane filtration.

Removal of wood extractivesduring mechanical andchemical pulpingSome CTMP mills have usedchemical precipitation and mi-croflotation to remove woodresins from process water cyclesin order to improve paper quali-ty and/or to recycle more water.At some mills the system is in-stalled prior to effluent treatmentin order to reduce the water tox-icity and to improve effluent treat-ment capacity. These solutionsbased on microflotation have rel-atively low investment costs. Ifwater consumption is low andwood extractive concentration ishigh, the chemical costs are in-creased and ultrafiltration is amore economical way to removeresin. In Fiber&Paper, No 4, 2002we presented the economic im-plementation for a sulfite pulpmill, where feed to evaporation isreduced, water is recycled andseparated resins are used as fuel.

The process solution, includingthe application of an ultrafiltra-tion system for mechanical pulp-ing mills, won the Metso EcoInno-vation prize in 2003.

Reduction of load to effluenttreatment and recipient byrecovering raw materialWood resins can be recoveredfrom mill waters and used for en-ergy production, for example. Atthe same time, natural wood basedpoorly biodegradable wood resinsare removed from the water. Theremoval of resins reduces the tox-icity of the effluent prior to the bi-ological treatment and improvesthe quality of treated effluent.

One way to reduce effluentload and waste amount is with therecovery of coating colors. The re-covery of coating colors by ultra-

filtration can pay investment costsback in a short period based onsavings in coating chemicals. Inaddition, the recovery system re-duces solid load from effluenttreatment and reduces the amountof dumped waste. The operationefficiency at effluent pre-treat-ment and secondary treatment isimproved, as the dispersion agentsand colloidal solids are recoveredto papermaking.

Closing the water cycles at recycled fiber millsIn recycled fiber, sticky-concen-trations are increasing due tochanges in raw material quality.The macrostickies can be removedwith screening, but microstickiesand potential stickies are creatingrunnability problems, going throughscreens, cleaners and disc filterswith the fiber fraction to the pa-per machine water system. An al-ternative to reduce the amount ofstickies in water cycles is to treatpress filtrate, instead of clear fil-trate, with microflotation.

In the deinking process a lot ofwater is removed with rejects toreject dewatering and a relativelylarge amount of make-up water isneeded. We prefer to discharge allthe reject press water to biologi-cal purification. Although the sol-id concentration may be low, therecycling of that water increasesthe concentration of potentialstickies and may cause problemsat the paper machine. We are in-troducing the implementation ofan aerobic bioreactor based sys-tem to purify mill waters and totake additional make-up water tothe deinking process through thebioreactor system, when needed.

Role of biological treatmentin closing the water cycles Biological water treatment re-duces concentrations of organicmaterial (typically measured asCOD and BOD). The removal oforganic acids results in an increasein pH, which in turn results in pre-cipitation and the removal ofhardness salts and heavy metals.Sulfides are odorous and increasecorrosion potential. The aerobicbiological kidney also reduces

anaerobic compounds, odor prob-lems and biocide consumption.

Zero effluent mills, which haveno biological kidneys, have facedsome problems. The high levels offines, salts and organic impuritiesinterfere with the wet end chem-istry. Decreased wire section reten-tion has resulted in larger doses ofretention chemicals and in the useof more expensive chemicals. Somemills have had corrosion problemsand a lot of older piping has beenreplaced. Caramel-like depositshave been found on such places asmachine surfaces, ventilation ductsand the ceiling. The need for ma-chine and ventilation system clean-ing and maintenance is high. Thereis a bad odor in the mill workingair and even in the product. An in-creased biocide dosage is needed,which is expensive, and does notmeet the requirements of sustain-able development.

The effect of biological kidneyson white water quality at OCC-packaging paper mills has been vi-sualized in figure 1. The concen-trations are only indicative andthey depend on mill solutions.

In cases A and B the water go-ing to biological treatment hasbeen minimized and only rejectpress water is taken in. A biggerkidney flow through biologicaltreatment has been introduced incase D. In case C, without biolog-ical purification, a lower water pHis evaluated, which increases thebiological activity and the CODload slightly. In addition, morechemicals are needed for the wa-ter system and machine washingin this case. If, in case D, ultrafil-tration was installed after the bi-ological loop (like in case B), theconcentrations would be roughlythe same as are given for theshown and preferred alternative.

Our solution is based on thesystem according to case D. It in-cludes two separate kidney loops.Biological treatment is used atstock preparation as a kidney.Ultrafiltration is used to produceshower water from PM filtrates.The benefits of the solution are asfollows.

Independent kidneyoperations mean more stablemill processesDeposition risks at the paper ma-chine are minimized when themixing of water of different tem-perature and chemical composi-tions is minimized.

Chemical costs decrease whenultrafiltration removes stickies,bacteria and cationic charge fromthe PM water loop.

Dewaterability at the papermachine is better when ultrafil-trated PM white water is used in-stead of biologically treated wa-ter. This saves energy and givespotential for capacity increase.

The investment costs for theconventional solution (case A)and the zero effluent Metso solu-tion (case D) are at the same lev-el. This is made possible becausethe bioreactor process used togain the kidney effect is much sim-

pler than conventional effluenttreatment with high purificationrequirements.

Future water managementTight mill closure requires a newway of thinking. Economical so-lutions need an approach that ismill-wide and exceeds profit cen-ter limits. It should also be keptin mind that savings or lossesthrough mill runnability andproduct quality are much morecritical for mill profitability thanwater treatment costs. In the fu-ture, water management will be -instead of effluent treatment - anessential part of the process forgaining product quality and millrunnability criteria, in the waymechanical fiber cleaning was re-garded earlier. �

GentleBarking- a log debarking method for higher yield◗ B Y A N T T I T O H K A L A

Chemical pulp mills have increasingly based their production on eucalyptus and acacia fromplantations. This trend has brought new challenges to the debarking process: in other words, howto reduce wood losses due to fragile wood species and a high bark content in chips resulting fromtough, stringy bark. Metso Paper has developed a revolutionary process improvement, GentleBarking(pat. pending), to eliminate these quality problems in handling expensive pulp mill raw materials.

GentleBarking method results in less wood loss, better chip quality, lower operating and

13

Process development in debarkingPulp and paper mills have been de-barking pulp-wood in debarkingdrums for over a century. Through-out the years, the basic principleof the process has remained un-changed. The pile of logs fed in-to the drum is put into a cross-wise tumbling or rolling motionby rotating the drum, which is fit-ted with log lifters mounted on theinside of the drum shell. Thewhole mass of logs moves aheadslowly along the drum length be-cause the drum slopes down to-wards the discharge opening.While tumbling and rolling insidethe drum, the logs rub and hitagainst each other and barkloosens from the log surface. Thedrum shell has slots throughwhich the loose bark should comeout of the drum. In other words,the barking drum is a combina-tion of debarker and bark sepa-ration screen.

Over the course of time, themethod has developed from batchdebarking to a continuous de-barking process. In batch de-barking, the debarking drum isfilled to a high degree while keep-ing the discharge gate closed androtating the drum. The batchtumbles in the drum until the logsare debarked, the gate is openedand the logs are discharged grad-

ually from the drum. This methodis still used by some mills wherethe prime target is not to minimizewood loss or to focus on the qual-ity of the end product but insteadto overemphasize log cleanliness.This debarking method may causemore than 10% wood loss and avery high percentage of brokenlogs and broomed log ends.

During the last 20 years, whilerequired debarking line capacitieshave risen to up to 300-350 solidm3/h, drum debarking has beendeveloped into a process wherelogs are fed continuously into thedrum and also discharged contin-uously from the drum by adjust-ing the discharge gate position.The aim of this method is to main-tain an even discharge rate from

the drum by weighing the log flowon the drum discharge conveyor.The correct retention time in thedrum is achieved by measuring thedrum weight and by adjusting thedischarge gate position. In theevent of an operational distur-bance in the process line after thedebarking drum, for instance achipper blockage or a switch-offby the metal detector, the dis-charge gate is closed and the drumcontinues running. This methodalso generates plenty of wood lossdue to discharge gate movements,and it may result in an uneven logflow to the chipper infeed, thusmaking the chipper line suscepti-ble to further disturbances.

In the two methods mentionedabove the aim is to remove the bark

from the drum through the barkslots, onto a bark conveyor situat-ed below the drum. To debarkwood species with stringy, toughbark, which is also difficult tocrush into small pieces, separationof the loose bark requires a longbarking drum although a muchshorter drum length would be ad-equate to debark the logs. In spiteof the length of the barking drumand the number of slots, a greatamount of loose eucalyptus or aca-cia bark, for instance, still exitswith logs from the discharge endof the drum onto the chipper line.In the chips, this bark is regardedas a serious contaminant unless itcan be separated from the log flow.Drawbacks of the methods de-scribed above:

Spruce logs in the drum, 10 m frominfeed. Log length 1-3 m, dia 15 cm.Drum length 35 m, dia 5 m. Drumrotation speed 7.5 rpm. Debarkingcapacity 180 sob-m3h.

Eucalyptus globulus logs in thedrum, 8 m from infeed. Log length2.4 m, dia 15-20 cm. Drum length30 m, dia 5 m. Drum rotation speed6.3 rpm. Debarking capacity 180sob-m3/h.

The same Eucalyptus globulus de-barking process, the logs have nowtravelled 15 m from the point of in-feed and are already clean.

The operating principle of theGentleBarking process is simple andunique. The drum is only for de-barking the logs and the loose barkis separated from the log flow with aspecial conveyor.

In spite of the bark slots, a greatamount of loose bark still exits withlogs from the discharge end of thedrum, as shown in this picture of aconventional debarking process.

maintenance costs and higher uptime.

◗ Substantial wood loss due totoo long retention time

◗ Variation in chip quality due touneven operation

◗ High breakdown frequency

◗ High percentage of bark inchips for certain wood species

To eliminate these drawbacks,Metso Paper has developed a rev-olutionary debarking method. Asan investment, the new method isalso considerably less expensiveand the process much simpler tocontrol.

Mill-scale studiesOne stimulus to this innovationwas the author’s observationwhen he visited a eucalyptuswood room where it was possibleto see inside the debarking drum,about 10 m from the infeed end.Although the drum of this plantwas about 35 m long, the barkhad clearly been removed fromthe log surface in the first 10 m ofthe drum length. This gave Metsothe impetus to carry out mill-scalestudies with various wood specieson how the debarking processprogresses inside the drum. In allcases where eucalyptus is de-barked in a debarking drum, thebark is removed from the log sur-face in the first 8-12 m of drumlength. These studies clearly show

that as far as the pure debarkingprocess is concerned, the remain-der of the drum length, the final15-25 m, is unnecessary and caus-es wood breakage and unreason-ably high wood loss. Similar ob-servations have been made aboutspruce debarking, with less dra-matic consequences.

The challenge is therefore toseparate the bark effectively fromthe log flow after debarking.Metso Paper had already solvedthis problem by developing an ef-fective bark separation methodfor the chipper line after the de-barking drum. As describedabove, an additional bark sepa-ration system is necessary for eu-calyptus and acacia debarkingsystems even if the drum shell hasbark slots. Compared to the ear-lier equipment, the bark separa-tion method developed by Metsoseparates the bark from the chip-per feed line more effectively andreduces wood loss.

Benefits of GentleBarkingThe significant advantage ofGentleBarking is a shorter bark-ing drum allowing less retentiontime, which means fewer woodlosses and less wood breakage.

Another improvement is theeven discharge rate from the de-barking drum achieved with afundamental change in the dis-

charge gate operating principle. Inthe new method, the dischargegate does not function as a sluice-gate at all, but instead has beenreplaced with a regulating devicecausing minimal interference tothe smoothness of the log flow.This means that one substantialsource of log breakage and woodloss has been eliminated from theprocess. The function of the reg-ulator device is merely to set thedrum filling degree at a levelwhich corresponds to the prevail-ing debarking conditions. On theother hand, the line capacity can-not be regulated by the positionof the gate but only by the amountof logs loaded onto the log re-ceiving conveyor. This regulatordevice does not close the outlet ofthe drum when interruptions inthe line occur, instead the wholeline stops and when the distur-bance has been rectified the lineis restarted from the stabilized sit-uation.

Because the loose bark is notseparated from the log flow in thebarking drum, the drum shell hasno slots, which means that thebark chutes and bark conveyorunder the drum are no longerneeded and the elevation height ofthe entire debarking line can be re-duced by several meters. Thisbrings substantial savings in con-struction costs and space require-

ments, which improves and facil-itates the utilization of space in thearea.

The GentleBarking method al-so simplifies the transition to acompletely automatic processcontrol, which prevents human er-ror in process operations andeliminates differences between theworking procedures of shiftcrews, usually seen as quantitativeand qualitative variations in pro-duction. Further benefits areachieved through longer drumlifetime and less maintenance.

In short, the new GentleBarkingmethod results in less wood loss,better chip quality, lower operat-ing and maintenance costs andhigher uptime. Furthermore, thetotal investment cost of the sys-tem is much lower than that ofpresent conventional methods. �

Pulp bale de-wiring processThe latest development in pulp bale handling is a com-plete process for bale de-wiring introduced by Metso Paper. The first com-pany to apply this technology is the Slovakian pulp and paper producerNeusiedler SCP, a.s. (former SCP Ruzomberok, a.s.), a member of theNeusiedler Group. The complete process comprises all equipment needed for the handling and de-wiring of both unitized and individual bales, as wellas for transportation to the pulpers prior to the paper machine.

Smart solutions The new de-wiring line utilizes allthe smart solutions within the pre-viously introduced RobobalingTechnology concept. In just fouryears, Robobaling Technology hasbecome renowned for deliveringequipment combining high oper-ational safety with high capacity.

“We are very satisfied with thecompleted development work.Now we want to get going withthe marketing of the de-wiringline so our customers can makeuse of our first class equipment,”says Mats Arnberg, Sales Manager.

Superior to competitorsThe high capacity is partly due tothe built-in self-diagnosis systemwith auto-start, which permits an

alternative operation mode in caseof disturbances. This means fewshutdowns of short duration.Stefan Nordhälling, who is re-sponsible for the machines, ex-plains that there are a number ofbuilt-in sensors sensing when themachine is in motion. If there isno indication of motion an alarmis shown on the display. It takesapproximately 30 seconds to de-wire a bale. One of the many ad-vantages of the new de-wiringline, which can be adapted to allbales on the market, is its “excel-lent de-wiring efficiency”, ac-cording to Nordhälling. “Thanksto a built-in metal detector, balesthat cannot be properly de-wiredare collected with a reject con-veyor,” he explains.

During the development of to-day’s modern de-wiring equip-ment, the basic philosophy hasbeen to design the machines inmodules ready for operation. Allmachines and conveyors areequipped with the PLC control sys-tem and a field bus technique,

which means less programmingand cable work during installation.

First installation toRuzomberokRuzomberok is Slovakia’s lead-ing manufacturer of wood-freegraphic and office paper andboard. All products within thecompany’s wide production pro-gram are intended for a specialfurther application. Ruzomberokhas highly specialized operationsaccording to Western EuropeanStandards, with five paper ma-chines producing 340,000 tons of different quality papers andboards per year.

Ruzomberok is now investingin a completely new de-wiringline. Furthermore, the present de-wiring line and pulp line are be-ing upgraded from 350 BDMT/Dto 800 BDMT/D of hardwoodpulp. The increase in producedpulp is necessary to meet with in-creased requirements after the pa-

per mill’s reconstruction of PM18. Thanks to the reconstruction,production of copying paper hasalmost doubled, from 160,000tons to 300,000 tons per year.

The bale de-wiring line consistsof a conveyor system, a combineddown-stacker and a unit de-wiringsystem, a single bale de-wiring sys-tem (Robocoiler™), a metal de-tector system, a Robotechnologycontrol system with remote access,engineering and erection supervi-sion. Embedded software and con-trol systems in the equipment willfacilitate short erection and start-up times. The scope also includescheckout, start-up and training.

Project implementation“Assembly and start-up are esti-mated at two weeks, starting atthe beginning of October. Onereason this is feasible is that wealso have combined down-stack-ing and unit de-wiring,” explainsNordhälling.

A standard solution for thecontrol system is a modern oper-ator interface with touch dis-plays. There is a minimum train-ing time for the operators and thisfacilitates maintenance and tradi-tional supervision. The trou-bleshooting possibilities havebeen greatly appreciated by cus-tomers. Should Ruzomberok needassistance in spite of the excellentreliability of the equipment, thereis remote access included in thedelivery for the benefit of the cus-tomer in case of any problems.

Metso Paper has a long-termand relatively strong position inthe mill as regards chemical andmechanical pulping and wood-handling. This has proven benefi-cial. “The specialists within theSCP appreciate Metso Paper’stechnical solutions, professionalapproach, flexibility and localpresence. This has resulted in or-ders totaling 10 million euros inthe last eight months. To Metso’s

advantage were the very reliablekey machine Robocoiler™ and asimple de-wiring process. Flexibletechnical solutions secure separateoperations on the two de-wiringlines,” points out Borivoj Tomis,Managing Director of MetsoPaper Czech Republic. �

The company has begun a major rebuild project at their mill in Chandler, Québec, Canada.

Chandler PM 1 has a wire width of 6.8 m. It was originally installed in 1963and rebuilt by Valmet in the late 1980s.

Nippon Paper Kushiro Mill

The Nippon Paper Kushiro mill,located on Hokkaido Island innorthern Japan, makes about 1 200 tons of printing paper a day,with about 90% of the output be-ing newsprint. The three papermachines at Kushiro are Bel-BaieII units which were installed andrebuilt between 1960 and 1977.

The mill uses a mixture ofdeinked pulp (DIP), thermome-chanical pulp (TMP) and bleachedkraft pulp (BKP) to feed the threenewsprint machines. DIP is by farthe major component of the fur-nish, with the proportions ofDIP/TMP/BKP varying somewhatbut DIP for newsprint generallyincreasing.

There are several DIP lines atthe mill making a total of 920 tonsper day. Each of the lines consistsof a pulper, rough screen, flotationdeinking, fine screening, peroxidebleaching and after-washing.Incoming raw material for the DIPlines consists of both old news-papers (ONP) and old magazines(OMG).

In an effort to get better con-trol of the ash content in the finalproduct, approximately two yearsago the mill decided to install akajaaniRMi unit to monitor ashlevels in the DIP. The analyzer wasdeveloped mainly for retentionmonitoring and control on the wetend of paper machines but, afterdiscussions with the Kushiro mill,Metso Automation suggested thatits advanced ash measuring capa-bilities might be a good solution.Kushiro agreed and thus becamethe first mill in Asia, and one ofthe first in the world, to use thenew generation RMi to measureash in DIP.

A balancing act in the pressroomAsh content is very tightly speci-fied and monitored by the mill’scustomers, which are mainly thevery big, and demanding, news-paper publishers in Japan. Con-tracts for newsprint specify ashranges, which are managed verystrictly. These specifications arerequired to balance the competingdemands of opacity and strength,with ash being good for opacitybut bad for strength and pressroom runnability.

The ash level in the DIP furnishvaries widely, since the ash con-tent in the incoming old newspa-pers and magazines fluctuatesfrom day to day and even fromminute to minute. Therefore thepaper mill has a balancing act ofits own to perform.

“We have three DIP lines eachwith different ash levels. In addi-tion, we are mixing in TMP andBKP, so the ash is fluctuating all

Ryuzo Shibano, Deputy General Managerof the Instrumentation Department, saysthe results have been very good, with the

ash content much more stable.

Japanese producer Nippon Paper Industries is usingtwo Kajaani systems in a novel way to keepnewsprint quality within tight product specificationsand minimize chemical costs. It is also among thefirst in the world to use the kajaaniRMi retentionanalyzer to monitor ash in DIP.

the time,” says Ryuzo Shibano,Deputy General Manager of theInstrumentation Department atKushiro mill. “To get control overthe situation we installed the an-alyzer with three sampling points,one at the end of each line just be-fore the mixing chest.”

Before the kajaaniRMi systemwas installed the mill lacked anyrapid means of monitoring ashlevels in the DIP furnish being fedto the paper machines. The onlymeasurement it had was at the endof the machine, where the QCSsystem measured ash in the sheetjust before the reel. That meantthere was a very long delay be-tween the production of the DIPand the measurement of ash con-tent at the reel. It therefore tooka long time before the operatorsknew the result of any correctiveactions that they had taken andby the time they got those resultsthe actual situation could havechanged again.

Much faster corrective actionShibano explains further: “Beforethe RMi ash monitor was in-stalled, the process was not easi-ly controlled. The ratio of ONPand OMG is generally kept con-stant and OMG has a largeamount of clay or ash since it ismostly coated paper. If there wereany changes in ash levels, wewould have to wait until the endof the paper machine to see whatthey were. It was not very directfeedback, meaning we could bemaking a large amount of off-specpaper while we tried to get the ashback on target. And by the timethe paper showed up on the reel,

the ash content of the incomingONP and OMG could easily havechanged. It quite simply wasn’tvery precise.”

Since the installation of theRMi, the situation has changeddramatically, says Shibano. Theoperators confirm that it will bea very useful tool, making it mucheasier to monitor and control theash level on each of the three DIPlines. If ash is too high, they cancut the amount of OMG comingin immediately. On the otherhand, if ash is too low, they canadd filler at the end of the line. Inthis way, the RMi is used as anextra window on the process con-ditions of the DIP lines.

“The results are excellent. Theash content in the paper at the endof the machine is much more sta-ble now,” says Shibano. “We aresimply able to use this as an ad-vanced measuring tool so we cantake corrective action much ear-lier and more directly. We lookedat other possible equipment andsolutions to monitor ash, but theKajaani system seemed to be themost technically advanced and thebest tool for us. We are verypleased with this decision.”

On-line residual ink andbrightness monitoringThe Kushiro mill is also using an-other Metso Automation moni-toring instrument to its advan-tage, to shorten the feedback loopand maintain tighter productspecs. It is the kajaaniCORMECi™brightness sensor. This in-linemeasurement is being used on theDIP lines, as well as on thebleached kraft pulp line, to keep

paper brightness more stable andin spec.

On the DIP lines the CORMECiis used for the continuous moni-toring of both brightness and resid-ual ink. “We have been very hap-py with the Cormec units,” saysShibano. “The CORMECi is veryuseful on the DIP line as well as onthe KP line. For the residual ink,we use the reading to adjust theflotation chemicals. If we are get-ting too much residual ink comingthrough with the washed stock wemake adjustments to remove moreink in the flotation process.”

On the BKP line, which makesmarket pulp for outside customersas well as for use on the newsprintmachines, the mill uses theCORMECi to keep bleachingchemical consumption undertighter control. “Just as we didwith the RMi for ash monitoring,we are using the CORMECi to getfaster feedback so we can makeadjustments to the bleaching chem-ical addition much more rapidly.Tighter controls mean fewerpeaks and valleys in the brightness

figures and that gives more on-tar-get pulp at the lowest possiblechemical cost. No overbleaching isneeded to keep within brightnessspecs anymore.”

A new way oflooking at thingsBy taking standard technologyand applying it in a novel way, theKushiro mill has been solving anissue that has long been a big dif-ficulty for DIP producers, name-ly wide fluctuations in the furnishfed to paper machines. Shibano isobviously pleased to have a solu-tion for these problems: “We solveda couple of problems at once. Wehave a much more stable qualityof stock reaching the paper ma-chines, which makes it easier tocontrol the process. That saves usa lot of headaches. At the sametime, and most importantly, wehave better quality control on thenewsprint we are making. Wehave the specs in a much tighterband, helping to lower costs andkeep our very demanding cus-tomers satisfied.” �

World’s fastest tissue

PM 1 is an impressive unit, quietly moving along at world record speeds.

Oji-Nepia m

Oji-Nepia’s PM 1at the Tokushima mill is an im-pressive piece of equipment.Moving along at average speedsof up to 2,050 m/min, it is knownas the world’s fastest tissue ma-chine. At the same time, the 6.1-m-wide unit is also Asia’s largesttissue machine, making around45,000 tons/yr of facial tissue,bath tissue and kitchen towelgrades.

PM 1, which is a ValmetPeriformer™ Crescent formerfrom Metso Paper, produces tissuewith a grammage range of be-tween 11 and 25.5 gsm. Built in1998, the machine features a two-layer headbox with dilution pro-filing, a steambox, a 5.5 m Yankeedryer and a soft nip calender. Wirewidth is 6.1 m and the sheet trims

at 6.03 m, with the resulting reelsbeing slit on the winder into three2-m-wide rolls for converting. Themill converts all of its tonnage onsite, with two Perini units handlingthe rolled products and 20 PCMClines producing boxed facial tis-sue, the mill’s main product.

PM 1 is clearly the baby of themill’s General Manager ofProduction, Satoshi Hosokawa, aman who speeds around his mill ata pace that comes quite close toequaling the machine. As he racesthrough the plant he points out var-ious improvements that have beenmade for speed and, perhaps moreimportantly, overall productivity.“I know this machine very well”,says Hosokawa. “We are continu-ously testing it and pushing to op-timize all of the variables.”

Following a meticulous and systematic optimizationprogram, coupled with the introduction of an 11gsm ‘Slim’ facial tissue grade, the Tokushima mill inJapan has succeeded in running PM 1 at 2,050m/min for five days straight.

The machine, and the mill,started up in December 1998.Approximately two years later, inOctober 2000, the company de-veloped and started making aproduct called “Slim Tissue”,which is 200 two-ply sheets of fa-cial tissue (197 x 229 mm) in acompact box just 50 mm high.This compared with the previ-ously existing facial tissue box,which was 65 mm high, meaningthat the Slim grade required an extremely low basis weight of 11gsm. In space-conscious Japan,the saving of 20% on the size ofthe omnipresent facial tissue boxmakes a large difference and thecompact box was a big hit withconsumers.

High average speed for best efficiencySlowly but surely the machinecrew has moved up the speedcurve, surpassing 2000 m/min forthe first time in December 2001.Then in December 2002,Tokushima succeeded in runningat 2,050 m/min for 80 hours in arow and most recently, in May ofthis year, PM 1 continued its

record by running at 2,050 for fivestraight days.

“We had hoped to be able toreach a maximum speed of 2,100m/min,” says Hosokawa, “but,due to limitations in the fanpump, it now appears that 2,050will be the top speed. I am not re-ally too concerned about the max-imum, it is more important tomaintain a high average speed,meaning better production effi-ciency.”

Hosokawa joined theTokushima mill in 2000, comingfrom the company’s Nagoya tis-sue mill, which is also sometimesreferred to as the Kasugai mill.Since then he has been very in-volved in the systematic effort tobring PM 1 up the speed curve.He has a very broad technicalbackground in the paper industry,starting in 1978 as an operator inthe Tomioka mill. Located nearthe Tokushima mill, Tomioka isdedicated mainly to printing andwriting grades. He worked therein various roles, including opera-tions, project management andmaintenance, from 1978 to 1993,before moving to the company’scorporate engineering headquar-ters in Tokyo for four years.

Relocating to the Nagoya millin 1997, Hosokawa got his firstexperience on tissue machines-there as Senior Production Man-ager. Then in March 2000, he wastransferred to Tokushima, wherehe assumed his present role as GMof Production.

Tokushima built on greenfield siteBefore 1998 all of Oji-Nepia’s tis-sue mills had been in the northernand eastern part of the country, withplants located in Tokyo, Nagoyaand Hokkaido Island. Based on astrategy of reaching the southernand western markets in Japan, Oji-Nepia decided to build the machineat a new mill, essentially alongsidebut across the river from the exist-ing Tomioka integrated printingand writing paper mill.

During the first two years afterstartup, the weak tissue marketconditions in Japan forced Oji-Nepia to run the machine at a re-

duced rate. This proved to be agood time for the new crew tolearn about the big new machineas most of the 80 mill workers atTokushima came from the nearbyTomioka and Kanzaki printing pa-per mills, with no previous tissuemaking experience. The reducedproduction speed due to the weakmarket, coupled with intensivetraining, provided ideal condi-tions for the new operators to getaccustomed to the tissue machine.

Starting in 2000 the Tokushimateam has been working with thespeed up program which, Hoso-kawa says, has not always been ex-tremely smooth. “We sometimesupset the operation. For example,in 2000 as part of our effort tospeed up, we ran tests for threemonths to find the best Yankeedryer coating chemicals. Wecaused a lot of breaks due to theexperiments and I must admit mybosses were not very pleased. Butthey understand that trial and er-ror is part of learning and even-tually we came up with the bestchemicals and application method.”

Hosokawa concedes that, fornow, 2,050 m/min will be thepractical speed limit. “The limi-tation we now have is rather hardto get around: the fan pump feed-ing the headbox is at its practicalflow capacity, so reaching 2,100m/min or higher would require anew fan pump.” That, he believes,would be too large an investmentfor the expected benefit.

He had originally calculatedthat 2,100 m/min would be at-tainable in 2003 with the existingfan pump. But, due to market re-quirements for softer tissue to jus-tify higher prices, Hosokawa hadto change the jet/wire ratio late lastyear. While he had previouslybeen running the J/W ratio at 0.90it was upped to 0.93 to improvethe sheet softness. The increasedflow volume required for the high-er J/W ratio meant the fan pumphad topped out as far as capacitywas concerned at 2,050 m/min.

Blow box to eliminate ballooningAnother change was made in Aprilof this year when the mill installed

a blow box from Metso to increasesheet stability on the reel. This hashelped eliminate the sheet flutterand subsequent ballooning effectthat sometimes occurs between thesheet and the reel drum at highspeed, causing wrinkles.

Another key in the effort to runat or over 2000 m/min has beenthe Yankee dryer surface treat-ment methods that Tokushima hasused. Based on a Valmet system,the spray unit has been modified,says Hosokawa, to allow highproduction speeds while main-taining quality. He is understand-ably reluctant to reveal any detailsof the Yankee surface treatmenttechnique, although it is clear thatthis is one of the crucial elementsfor high speed production.

Machine crew very positiveHosokawa is pleased to point outthat the machine operators havebeen extremely cooperative inworking with him as they pursuehigher speeds. “The crew here isvery enjoyable to work with. Asis well-known in the paper indus-try, machine crews in many mills

can be reluctant to make changesto increase the speed since thatraises the risk of breaks. But theoperators here have a great ‘can-do’ attitude and they really puttheir heart into working togetherto get the best out of this ma-chine.”

He further explains that thismay partially be due to the factthat, when the PM started in1998, very few of the crew hadexperience in tissue making.Some had worked with papercoating at the nearby Tomiokamill, but they were free from anybias or preconceptions aboutwhat a tissue machine could orcould not do.

Clearly this can-do attitudehas been an asset as they havedone something that no other ma-chine crew in the world has ac-complished, namely running at2,050 m/min for extended peri-ods. Using the absolute latest tis-sue making technology fromMetso, coupled with a high levelof support from Oji-Nepia’s man-agement, the Tokushima PM 1team has made it look easy. �

A new kind of customer training course provided a freshopportunity for process and R&D engineers in the tissueindustry this spring. During four days in April at MetsoPaper in Karlstad, 20 engineers were offered deeper un-derstanding and a new perspective on the machinery theywork with daily.

Facts about the Metso Paper Karlstad Learning Center

For four days Metso Paper experts explainedevery detail of the press and Yankeesections, and every aspect of the tis-sue process applicable to these sec-tions. This four day course was thefirst launch in a new “Customertraining” product line at MetsoPaper in Karlstad. Instead of lo-cating the customer training on thecustomer’s own site, which wouldbe the traditional thing to do,Metso Paper in Karlstad decided totry a new angle. They gathered en-gineers from customer companiesall over the world in Karlstad. Thisarrangement made it possible for anumber of the experts at MetsoPaper Tissue Technology Center totake up a teaching role. All theteachers at this education weekwere in fact engineers at MetsoPaper Karlstad, experts in all as-pects of the press and Yankee sec-tions of a tissue paper machine.They all got a thorough introduc-tion to working as a teacher.

“It is a basic fact, of course, thatour teachers have an expert knowl-edge of their subject,” says MetsoPaper’s Madelen Richardsson.“But it is vital that they also havethe ability to pass this knowledgeon to their ‘students’. We also be-lieve it important to take advan-tage of the know-how and expe-rience that these students havefrom their own work.”

Deeper understanding“I feel that I now understand theprocess more fully, together withhaving a greater appreciation ofhow minor process changes can af-fect the drying process,” says KateLeach, Process Engineer at thePapermaking division of Georgia-Pacific in Ramsbottom, UK. Kategot her paper science degree lastyear at the Technical University ofUMIST in Manchester. After that

she has been working at theGeorgia-Pacific R&D center inFrance. Being fairly new to work-ing at a production site, she foundthe course gave her a good overviewof the different aspects of theYankee cylinder and air caps sys-tem. “I found the mechanical sec-tions of the course, such as Yankeecylinder crowning, fairly compre-hensive,” Kate explains. “I couldhave used some more help with thechemistry of coatings, though.”

Jyrki Leppäaho has been withMetsä Tissue as PM superintendentat the mill in Mänttä in centralFinland for about one and a halfyears. The discussions during thecourse, with teachers and other en-gineers, were of great value to him.“There were engineers on thiscourse from a number of coun-tries,” says Jyrki. “The discussionswere very useful; they gave me apicture of tissue making all over theworld. The group tasks were espe-cially useful in this aspect - this issomething you could well do moreof in training courses like this one.The theory classes were also good,and the teachers really knew theirsubjects well,” Jyrki concludes.

Reality kicked inJohan Bäck, Metsä-Tissue Katrine-fors, got proof beyond expectationof just how well this course reflect-ed real life. Just home from Karlstadhe was immediately involved insolving a problem he recognizedwell – it proved to be more or lessa copy of one of the group tasks.

Johan Bäck appreciated the factthat all theory lessons included dis-cussions. This made it possible toput new facts into a broader pic-ture, and understand the reality be-hind them. “This week was im-portant to me in my work,” he says.“I am quite new to tissue making,

coming from M-real Husum, whichmakes writing and printing paper.Since this course I have had a bet-ter understanding of how the pressroll and Yankee cylinder work to-gether to make good tissue paper.The teachers really knew their sub-jects, and they were able to conveythis knowledge to us engineers.”

Useful visit to R&D CenterThere was a general sense amongparticipants that Metso Paper was

right to let this course take place“at home” in Karlstad. This madeit possible to visit Metso Paper’spilot plants, and to get a closerlook at the details they had justbeen discussing. Most participantsalso felt that the course coveredthe right subjects, and in a goodway. “The time schedule was quitetight,” says Jyrki Leppäaho. “Butthat’s all right, it shows we usedthe time we had profitably. �

Metso Paper Karlstad Customer Training comprises six people:onemanager, two training coordinators and three designers involved with theproduction of training courses and training material.

The manager is Madelen Richardsson,a human science specialist withlong experience of working with education and training.For a number ofyears she was working with human resources issues at the Ericsson group.

Marika Samuelsson is one of the training coordinators,andresponsible for the “Press & Yankee Section Training”described in thisarticle.Marika used to be an engineer with Metso,went on to working witheducation elsewhere,and is now back with Metso Paper Karlstad.

The Metso Paper Karlstad Learning Center has two major tasks:

1. Training in connection with the delivery or rebuild of machinery.Thiskind of training is generally done on the mill site.Training thecustomer’s staff is an integrated part in the startup of new or rebuiltequipment.

2. Training as a product.Metso Paper Karlstad continuously tries to get allexpert knowledge in the Metso Company down on paper. In this waythe know-how can be further processed into training products.

“We systematically use the concept ‘training products’,”says MadelenRichardsson.“We want to stress the fact that they are products in their ownright.Our goal is to produce training products that really help people tolearn, rather than them just getting the information.”

Metso Paper has been giving courses in Sundsvall for some time andnow wants to market advanced training courses at Metso Paper inKarlstad.This April saw the first course being completed at Metso Paper inKarlstad, in the same building which harbors the Metso TechnologyCenter.Metso Paper Karlstad Learning Center itself is a concept,not abuilding. �

SachsenSachsen◗ B Y E E R O H A L M A R I

located in Germany, has been one of the world’stop three newsprint mills for over seven consecutive years - since 1996 - and is very likely to continue inthis position for the foreseeable future. The main factors that have influenced the achievement of thismagnificent record are a strong will to always improve, combined with extensive cooperation with Metso.This has enabled continuous production capacity improvement on the machine.

nn still on topThe latest rebuild as part of the machine’s improvement process was conducted successfully in January 24,2003, with the installation of a new suction roll shell to the press. The suction roll shell is made of a new,revolutionary powder metallurgical duplex stainless steel material named Duplok™, developed by Metso.Duplok has higher corrosion fatigue strength and longer shell lifetime than conventional stainless steelshells, even when operating at higher press nip loads.

Stora Enso Sachsen GmbH islocated in Eilenburg in Saxonystate in Germany, right next to theheart of the European market. PM1 was built by Valmet (Metso). Ithas a wire width of 10,000 mmand a design speed of 1700 m/min.The Sachsen mill was a greenfieldproject, which required a lot ofnew personal and intensive train-ing. At the time it was one of thebiggest foreign investments in thenewly formed German states. Themill produces recycled newsprintnamed “SAXES” from 100% re-covered paper (DIP), and it wasStora Enso’s first such mill. Themill also has its own deinkingplant for pulp.

Continuous developmentPM 1 started up on 31 August1994 at a world record speed of1243 m/min. The paper qualitywas good from the very begin-ning. Already by Christmas 1994,1600 m/min could be reached.After the start-up phase, the ma-chine was the world’s most pro-ductive newsprint machine for fiveyears (1996-2000). In 2001-2002

the machine was in the top three,and today it has climbed to toptwo after the latest machine im-provements. This is a magnificentrecord, bearing in mind that themachine uses conventional roll-nip-technology. Actually, theSachsen PM 1 is still the top ma-chine in the world running with-out a shoe press.

Sachsen mill’s main target is tostay in the top three newsprintmachines in the world, whilst al-so further improving paper qual-ity. To achieve this, the mill’s prod-ucts, processes and working meth-ods are constantly improved ac-cording to the latest and most en-vironmentally friendly develop-ments in technology. Another ob-jective is to achieve over 90% ef-fectiveness. In 2002, it was 89.7%,so the goal is getting close.

One early target was to in-crease the dewatering capacity ofthe wire and press sections and toimprove the cleanliness of themachine. In the first stage an op-timization process to find the bestfabrics for the press section wascarried out. In step two, a highvacuum suction box was installedin the wire section, which in-

creased the dry content of the webafter the wire section from 16%to 19% and also made the webmoisture profile more consistent.

The machine’s annual produc-tion capacity is now 330,000tons, which is considerably morethan the original design capacityof 280,000 tons per year. Pro-duction capacity development canbe seen in Table 1. The main fac-tors that have influenced this re-markable increase in productivi-ty are a strong will to always im-prove, along with extensive co-operation with Metso.

Cooperation with Metso - like a partnershipThe cooperation agreement be-tween Sachsen mill and MetsoPaper was already signed duringthe start-up phase of the machine.Cooperation has been very inten-sive right from the start. Therehave been four to five meetings ayear where many fruitful andvaluable discussions have beenheld. It is a platform for brain-storming and bringing up newideas and solutions. Dr. UlrichHöke, Manager Production &Technology, remarks: “With thiskind of cooperation we can hearthe latest developments in tech-nology and discuss any possibleproblems. You cannot stay as anisland; the improvement processis not good that way. Cooperationwith Metso is the best way to con-tinuously improve. The coopera-tion has been excellent. We can re-ally say that this is more like apartnership!” Both parties aremotivated to achieve the com-monly set high targets, and thewill to improve is always present.

“Having this cooperation hasbeen an effective forum to discussour machine’s bottlenecks and tofind clear solutions for them. It isnice to see where the current bot-tleneck is and to solve the prob-lem. Then we can see where thenext bottleneck is.” When a solu-tion is found, it is checked withcalculations and often also withtest trials on the machine. If theresults are good, the solution willbe installed on the machine.

“We think both sides benefitgreatly from this kind of cooper-ation,” says Dr. Höke. Metsowould definitely agree. The co-operation with Stora EnsoSachsen GmbH is a perfect ex-ample of what the Metso FutureCare concept is all about: it aimsat the lifecycle management ofcustomer processes through con-tinuous support and responsive-ness to changing needs.

Background of the latest rebuildIn 2000 - 2001, the machinereached its limit and the bottleneckwas the draw from the center roll.One problem area was that theedges of the pick-up felt weren’tlasting long enough, which ulti-mately caused a flipping problemon the edges of the paper web.

Schürmann explains: “In thelast months before the rebuild itwas becoming increasingly clearthat the dewatering capacity in thefirst two nips in the press sectionwas not enough, particularly forhigher grammages. The produc-tion speed had to be decreasedmore and more when we were run-ning our heaviest 48.8 g/m2 and 52g/m2 classes. The felts were be-coming very tight due to the con-ventional press nips, and with thegreater water amounts needed forhigher grammages the water re-

moval capacity was not sufficient.There was too much water in thenip, which acted like glue and fi-nally caused a web break.”

Knowing that the dryness afterthe wire section had previouslybeen improved to a very high lev-el corresponding to modern topmachines, it was natural to con-centrate on the press section andits limitations. The adjustment ofthe running parameters of thepress section types did not have anotable effect, and neither didchanging the felt. It was becom-ing clear that a nip load increasein the press section could be thesolution.

This meant there was a need formajor improvement. There was aspecific target to reduce breaks andshorten breaktimes, to have a bet-ter time efficiency. After commondiscussions it was decided to car-ry out some test trials by increas-ing the nip loads in the 1st and 2ndpress nips. The results were posi-tive: the dewatering capacity in thepress section got better, and it wasbelieved to be the right remedy tosolve the bottleneck. It was con-cluded that the last drop of po-tential could also be squeezed out

of the existing SymPress II with a4th press (see layout above) by in-creasing the nip loads. Now thequestion was how to find a solu-tion that enabled higher nip loads.The common fact is that press suc-tion roll loads are often limited bythe load limitations of the suctionroll shell material, which was al-so the case here. A new shoe presswas out of question because themill’s backlog did not permit a ma-chine downtime of the length thatsuch an installation would require.Instead, the solution was Duplok™.

Duplok - features, advantages andresultsDuplok is a new revolutionarypowder metallurgical duplexstainless steel material developedby Metso for suction roll shells. Ithas a higher corrosion fatiguestrength and longer shell lifetimethan conventional stainless steelshells even when operated athigher press loads.

The goal of the Duplok rebuildin Sachsen was to enable higherpress nip loads, and thus to in-crease the dewatering capacity.The Duplok suction roll shell isequipped with a grooved andblind-drilled polyurethane cover.Its large open surface area helpswater removal in an increased ni-pload. Due to the softer roll cov-er the felt lifetime is also longerand the press nip a little bit wider.

Thanks to the high strengthproperties of Duplok, the dimen-sions of the new suction roll shellbody could remain the same evenwith increased nip loads. Thereforemost of the components, for ex-ample the suction box and the

SymPress II

bearing parts of the existing roll,could easily be used with the newDuplok™ shell. In Sachsen, the suc-tion roll diameter increased by ca.40 mm due to the thicker roll cov-er. Before this new roll could bemounted, some components in thesurroundings had to be relocated.However, there was not much needto replace existing parts with newones. The new layout was designedin such a way that use of the olduncovered roll is also possible.

After careful planning, the in-stallation was conducted onJanuary 24, 2003. Test runs, pro-gram changes and start-up ranwithout any friction. The nip loadswere increased, and the dewater-ing capacity increased as planned.In addition, there was no need tochange the felt types in the presssection. Schürmann says: “Therewas a fear that due to the highernip loads the paper would bepressed too much and become toodense. This did not happen, andwe are very happy that there wereno negative effects on the paperquality at all. Conversely, porosi-ty and bulk actually improved!”

Schürmann continues: “With thenew Duplok suction roll, the nipload in the 1st nip was increased by13 kN/m. The load increase waseven bigger, 25 kN/m, in the 2nd nip.In addition to this, the vacuum lev-el in the suction roll was increasedtoo. These increased load and vac-uum levels are demanding and areonly possible to achieve with thenew Duplok suction roll shell ma-terial. This is due to its increased cor-rosion fatigue strength and im-proved corrosion resistance.” Thedetailed results of the Duplok re-build are presented in Table 2. Theresults prove that a higher dewater-ing capacity in the press section canbe utilized to increase production,especially when operating withheavy grades at high speeds.

“Our expectations have beenexceeded,” remarks Dr. Höke.“The speed increase that is a con-sequence of the higher dryness en-abled with this rebuild is remark-able. Since we got Duplok, run-ning at 1700 m/min is easy. Thespeed increase when running withour heavier grades, like 52 g/m2,

was amazingly even 150 m/min.This is something we did not ex-pect to achieve. So far it has beena success. The technology ofMetso is outstanding.”

“Making paper from 100 %DIP is very demanding,” continuesSchürmann, “because it is dirty,sticky, elastic and more likely tobreak. With Duplok, the machine’soverall runnability has improvedand the sheet break sensitivity hasdecreased. The higher nip loadshave to be proven over time, afterwe gain some more experience andcan optimize the process further.There are always certain problemswith higher nip loads, as they cutacross the usual limits used in thepapermaking industry. But, if thisconcept is going to run withoutproblems for the next few months,we are pretty sure many paper-makers will follow our example.”Following the excellent resultsgained with Duplok, Sachsen haspurchased a second Duplok suc-tion roll shell from Metso.

The futureCooperation with Metso will nat-urally also continue after theDuplok rebuild. The next projectis already approaching inSeptember 2003. Then there will bean extensive rebuild of many sec-tions of the machine: a new head-box, conversion of the existing wiresection to an OptiFormer, newHiRun Plus runnability boxes forthe first two sections of the dryergroup and a HS box in the 3rd sec-tion. Furthermore, the reversedgroup in the dryer section will beturned like a normal one.

“With the forthcoming rebuildwe are aiming for further runnabil-ity and paper quality improve-ments. After the rebuild, the newtarget will be 1850 m/min. It justconfirms that Metso has done a re-ally good job in the past, becausethe machine has such good re-serves,” praises Dr. Höke. �

Duplok™ in a nutshellDuplok is a revolutionary powdermetallurgical duplex stainless steelmaterial for suction roll shells,developed by Metso. Due to its finemicrostructure and high alloyingenabled with a powdermetallurgical manufacturing

method, Duplok shells have extremely high corrosion resistance andcorrosion fatigue strength. Powder metallurgy is a manufacturingtechnology where fully dense pieces are pressed out of metalpowder using high temperature and pressure.This method allowsthe manufacturing of alloys with significantly better strengthproperties and a higher purity level than those made withconventional methods, such as casting.

High strength properties and material quality contribute tolonger roll shell lifetime. In a press suction roll position, Duplok’s highcorrosion fatigue strength also gives possibilities for press nip loadincreases without changing suction roll dimensions and pressgeometry.Therefore Duplok can offer an easy way to increase thewater removal capacity at the press. Better water removal and higherpaper dryness after the press mean improved sheet wet strengthand machine runnability, and also a certain decrease in steamconsumption in the dryer section.The suction roll shell can also beequipped with a grooved soft cover that widens and softens thepress nip, thereby extending the felt lifetime at higher nip loads andthus increasing the dewatering capacity of the press section. In caseswhere press runnability issues or drying capacity in the dryingsection have been the bottleneck limiting paper machine speed,Duplok can be the key to production increase. �

How is a world papermaking speed record set? Obviously, thestarting point is well designed technology and a professionally man-aged commissioning project. But no two papermaking processesare alike; the papermaking furnish, production and quality re-quirements are often unique to that mill. Some on-site changes andfine tuning of the process are an inevitable part of every commis-sioning project and afterwards, when the world records are soughtafter. Teamwork is essential in the quest of world class perfor-mance.

In the fall of 2002, the PM 8 base paper machine at UPM-Kymmene’s Kymi Paper mill in Kuusankoski, Finland ran at anaverage speed of 1541 m/min over 24 hours, shattering the worldrecord for free-sheet fine paper machines. This achievement at-tests to the excellent rapport, mutual understanding, and team-work between Kymi Paper and Metso. During the speed trials thisdialog involved Metso’s on-site personnel and those at the facto-ries and research and development centers.

Metso’s remote diagnostics centers in Jyväskylä andTampere supported a team effort which propelled

Kymi Paper’s PM 8 to world record speeds.

Fast access to expertiseAt Kuusankoski this high level ofcommunication and teamwork isaided by a network of remote di-agnostics centers. Two of these cen-ters, in Metso Paper’s Rautpohja(Jyväskylä) plant and MetsoAutomation’s facility in Tampere,Finland, participated in the PM8speed trials. Experienced engineersat these sites saw the processchanging just as the operators sawit. Response tests and trials couldbe reviewed with the papermakersin the same time frame.

This online information net-work, which satisfies UPM-Kymmene’s security requirements,connects the mill’s papermakingprocess information to experts inpapermaking, quality control andprocess automation. In many cas-es the automation and paper-making specialists work togetherto solve a problem. With the ad-vanced state of today’s communi-cation networks, this model couldbe replicated on any paper ma-chine, anywhere in the world.

Stefan Fors, PM 8 productionmanager, sees the value of this com-munication after the machine start-up and during the speed trials:

“We saw a very fast responsewhen we were troubleshooting aproblem. Metso has strengths inRautpohja and Tampere, and thathas good value. With this service,

specialists could be called in moreeasily to define a problem and de-termine what follow-up is re-quired.”

“It helps us to analyze trials andoptimize the machine .Without theremote centers, the problem solv-ing process would have been slow-er and more costly,” he says.

A narrow window of stabilityA papermaker will tell you a sta-ble paper machine is a fast papermachine. When the sheet is un-stable and breaks are too fre-quent, speed will be cut back. Onthe other hand, if conditions lookideal the papermakers will shootfor as much speed as they can get.

Many papermakers, includingthose on PM 8, will also tell youthat they are operating in a verynarrow window of machine per-formance where stability and speedgo hand in hand. This narrow win-dow of operation is a particular is-sue for fine paper machines sincethe tension in the wet wood-freesheet relaxes . The delicate sheetmust be well supported, drawsmust be gentle and the sheet itselfmust have even quality.

The excellent process stabilityrequired for this machine can beachieved only when the process iswell measured and controlled likea finely tuned instrument. In thisrespect, PM 8 must be one of the

most instrumented machines inthe world, with associated con-trols that stabilize each of the sub-processes.

Well measured machine, stable controlsThe machine is equipped with atwo-scanner PaperIQ quality con-trol system and a metsoDNA con-trol network.

ness. The machine’s wet end is sta-bilized by a multi-variable controlcalled IQWetendMD which usesthe measurements from wet endanalyzers in combination with dryend measurements of grammage,moisture and ash. Short termvariations in sheet quality aretherefore stabilized at the sourcebefore the sheet is formed. Forshas been pleased with the stabili-ty that this control adds and citesthe easiness of the machine star-tups and grade changes.

Metso Paper’s Arto Puranenhad been looking at excessive vi-brations in wire guide rolls fromthe Rautpohja center. Over a pe-riod of a few hours he comparedthe irregular vibration curves ofthese rolls to normal vibrationcurves (vibration frequency com-pared to speed). Drawing on hisexperience, he deduced that theserolls were filling with water. Hisdiagnosis proved correct and theproblem was resolved, withoutthe need for a time consuming in-mill study and further off-lineanalyses.

Metso Automation’s AnttiNissinen and Pasi Virtanen foundperiodic process instabilities fromthe remote center in Tampere. Inone case the stock consistency af-ter the blend chest varied consid-erably, over a 70 minute cycle,even when the consistencies of in-coming stocks to the blend chestwere correct. The cause of thevariation was isolated to poorlytimed operation of washing show-ers in the disc filter saveall. In an-other case the headbox jet to wireratio control became unstable atcertain speeds. That problem wassolved by retuning the loop. Thedosing rate and timing of an-tifoam agent was also changed toeliminate wet end disturbances.To remove another speed obsta-cle, Mikko Härkönen found thatthe bolts on a press felt guide rollneeded to be tightened to elimi-nate excessive vibrations.

Fors notes that a number ofthese improvements were madeproactively and were transparentto the operating crew.

Staying in the windowThe only open draw in the wet endof the machine occurs when thesheet releases from the centerpress roll. At this point the deli-cate free-sheet is exposed to a va-riety of forces including its ownweight and velocity, air pressurebalance across the open sheet areaand adhesion to the center roll. Toachieve the lowest stress on thesheet, hence the best runnabilityand speed, these forces must be in

perfect balance.The mill equipped the machine

with a variety of new and innov-ative measurements that give themand Metso engineers a window in-to this area, plus an opportunityto study it and exert some controlover it. Release point, hence re-lease angle, is measured by a lasersensor, average moisture and CDprofiles by IQInsight and cation-ic charge demand by kajaaniCATi.These measurements have shownhow the release point varies withmoisture and charge.

With this sensitivity to releasepoint and draws the papermakersare very aware of changes andhow to react to them. “Runningover 1500 m/min and with lowergrammages the operating windowis very narrow and the draws arecritical. But, we have been able tohit that window and stay withinit,” says Fors. �

Charge Demand

Moisture

The center roll release angle varies with cationic charge demand (graph onthe left) and the wet moisture varies with charge demand (graph on theright). This visibility has helped the papermakers to effectively manage sheetdraws for good runnability and high speed.

HeadBoxBoostfor higher quality production

◗ B Y PA S I K O I V I S T O

Ensuring quality production time is one of the most important targets for papermakers. Headbox servicinghas also become more and more important due to needs for improved runnability and paper quality.

Metso Paper Service has a unique ability to serve customers with headbox solutions. Metso has a very strongbackground as a headbox manufacturer, decades of experience in on-site servicing, and deep technologicalheadbox know-how (especially Valmet and Beloit headboxes), as well as advanced process know-how. This,combined with the customer’sown papermaking and productionline knowledge, enables mills tofully utilize the potential of theirmachinery and processes.

An optimally functioning head-box allows everything else in thepapermaking process to functionat its best, with high runnabilityand quality. Therefore a boost toheadbox performance is actuallya boost to the whole productionline. This is what Metso Paper’sHeadBoxBoost offers.

Through the Metso FutureCare business concept, our goal isto maintain the competitiveness ofour customers’ core processes andto develop them throughout their

lifecycles. To accomplish this, weare changing our role from a tra-ditional machine supplier to a per-formance provider.

Metso Paper aims at customersuccess. Customers can rely onour expertise at every stage oftheir process lifetime from invest-ment and planning, through as-sembly, start-up, optimization,monitoring, service and rebuilds,to new installations. It is highlybeneficial for papermakers to or-ganize their production line’s per-formance management by agree-ing on clearly defined responsi-bilities for the mill and for MetsoPaper. In this way, the scope of co-

operation can best be tailored toeach customer’s specific needs.

Expert support for better profilesSeveral paper mills have alreadybenefited from HeadBoxBoost. Inone case, problems with the head-box dilution profile control seri-ously affected end product quali-ty. After expert testing and analy-sis Metso Paper Service estab-lished that the dilution valveswere worn out and some werebroken. The valves were openedand cleaned on site, and seals werechanged where needed. Totallyworn out valves were replaced

with new ones. These actions suc-cessfully returned the headbox toits proper profile level.

Metso Paper Service then sug-gested a detailed plan for futurevalve maintenance and replace-ment. This HeadBoxBoost coop-eration is proceeding well, andthe recommendations will ensurethat the mill can maintain the cor-rect headbox profile well into thefuture.

Better results, better qualityMetso Paper’s HeadBoxBoostprovides more efficient mainte-nance, resulting in better runna-bility and paper quality. The per-formance enhancements areachieved through improvementsin dry weight profiles and otherpaper quality properties, as wellas in the elimination of streakinessproblems and distorted impinge-ment, a decreased need for sliceopening adjustments, and im-proved slice control.

It is increasingly recognizedthat agreement based services givemills the best results, building onthe strengths of both mill and ser-vice provider. HeadBoxBoost is anassortment of tailored, focusedand chained headbox service ac-tions, covering everything fromindividual trouble shooting visitsand condition tests, to full head-

box maintenance responsibilityagreements. Regular preventivemaintenance of the headbox helpsmaintain and improve paper qual-ity, and provides optimumrunnability. Together the cus-tomer and Metso Paper can designa package that meets the exactneeds of the headbox and there-by optimizes its performance.HeadBoxBoost agreements reducemaintenance costs, reduce un-planned shutdowns due to head-box equipment failure, and con-tribute to flawless operation.

Clear benefitsThe headbox service, covered bya service agreement, ensures thatthe actions needed to securesmooth operation are identified,and that the required resources arearranged. One clear benefit of along-term relationship with MetsoPaper Service is that it makes ser-vicing easier and more efficient.The knowledge obtained from along-term service history and pre-vious measurement results is veryuseful in problem situations, andcan be used to identify whether themain cause of the problem is theheadbox or some other part of themachine. To best meet customerneed, the scope of cooperationagreements can extend from test-ing and analyzing right through to

larger maintenance and service co-operation agreements between thecustomer and Metso.

Metso Paper’s service portfolio includes a large number of maintenance and material ser-vices to ensure the most effective equipment and process operation at our customer’s mills.The products available vary from reactive maintenance and methods developed for processoptimization to remote diagnostic centers built for process monitoring.

Metso Paper has recently introduced a reliability program, theReliabilityBoost, which is a streamlined reliability-centered maintenancemethodology for pulp and paper industry uses. The method providesan analytical way to optimize production line maintenance strategy byusing various maintenance techniques.

Targets of ReliabilityBoostThe main objective of Reliability-Boost is to reduce maintenancecosts and improve asset reliabili-ty, by focusing on the most im-portant functions of the systems,and avoiding or removing main-tenance actions that are not strict-ly necessary. To obtain these tar-gets a maintenance program willbe determined, focusing on opti-mized maintenance efforts. Thisaims for the required reliability inthe most economical way, withoutsacrificing safety or the environ-ment. Furthermore, it focuses onthe functional importance of apiece of equipment and its fail-ure/repair history, rather than ontraditional “time-directed” over-haul tasks.

Benefits of ReliabilityBoostThrough reliability analysis and acommon reliability database, thefollowing benefits have typicallybeen gained:

◗ Better efficiency and usabilitydue to fewer unexpectedfailures

◗ Better maintenance costefficiency as a result ofextended equipment life cycle

◗ Improved asset reliability

ReliabilityBoostimplementationThe implementation of Reliability-Boost starts with the establish-ment of an analysis group. Thisgroup consists of the customer’soperating, maintenance and pro-duction personnel along with

from Metso’s process, equipmentand maintenance specialists.

The work starts by evaluatingthe criticality of the process anddifferent pieces of process equip-ment. The criticality of the equip-ment is defined using several cri-teria and weighting factors. Thesecriteria include:

◗ Criticality of failures from theprocess viewpoint

◗ Sensitivity of equipment to failures

◗ Ease of maintenance

◗ Environmental effects and safety

After the criticality analysis, afailure mode and effect analysis ismade for the most critical equip-ment. The results of this analysisare preventive maintenance tasksand objects.

Based on the results of the re-liability analysis, a revised pre-ventive maintenance plan is com-piled, and a spare part recom-mendation can also be made.

The whole ReliabilityBoostprocess takes place in very closeco-operation between the cus-tomer and Metso. In this way it ispossible to combine the practicalexperience and operation and

maintenance history of customerpersonnel with the theoretical de-sign knowledge and service expe-rience of Metso personnel.

The revised preventive mainte-nance programs result in improvedavailability and lower mainte-nance costs and form a basis forfurther productivity development.At the same time spare part opti-mization can also be carried out.In practice this means either pur-chasing new critical spares or get-ting rid of obsolete spare parts.

ReliabilityBoost as part ofpartner agreementoperations at theMetsä–Botnia Rauma millIn March 2002, Metsä-BotniaRauma signed a partner agreementwith Metso Paper. One co-operationtask was to upgrade maintenanceprograms, and this upgrading wascarried out using applied RCM.

First applied RCMimplementation targetsThe areas focused on at that timewere the main machinery forSuperBatch™ cooking and theTwinRoll™ presses. Thanks toapplied RCM, the developmentgroups and maintenance manage-ment, the customer’s productionlosses have decreased noticeablyin the target area.

During the last year availabili-ty has risen to 99% in the cook-ing area including the TwinRollpresses, but despite this mainte-nance costs have not risen as a con-sequence. The forecast availabili-ty for 2003 is 99.4%. By planning

together more we can get betterand better results.

Next ReliabilityBoost tasks atMetsä-Botnia Rauma millMB Rauma has been pleased withthe operations and improvementsachieved so far. Concrete proof ofthis is the fact that under the newagreement our maintenance re-sponsibility has been extended tothe wood room, and that devel-opment now covers operationsfrom the log feed to the firstbrown stock washing press.

ReliabilityBoost’s tasks for2003 are to optimize mainte-nance actions in the wood prepa-ration area. The main machinesfor wood preparation are theGentleFeed™ conveyor, theEasyTyre™ barking drums, thechipper feed system and theRauma GS™ chipper.

Future analysis targets alsocover the pulp drying area, andspecifically the wet end, cutter lay-boy and bale press. �

Tissue Makershave seen better sheet quality and runnability over much longer periods

HIGH-TECH RUBBER COVERS IMPROVE HARDNESS STABILITY, EXTEND PRESSURE

41

To achieve longer periods of good machine performance and longerroll cover lifetimes, the tissue industry has been looking for rubber cov-ers with more stable hardness properties and better resistance to un-even wear. Now, with a new rubber cover formulation developed byMetso Paper at its Clarks Summit, Pennsylvania facility, those 90-dayregrinding intervals are being comfortably stretched to 120 days, andover. Tissue makers like Cellu Tissue, in East Hartford, Connecticutand CityForest in Ladysmith, Wisconsin, are confident of achievingeven longer lifetimes. To date, 60 of these roll coverings, calledPressGator ZL, are in service.

Maintaining the sweet spotA tissue machine pressure rollmust press the sheet very evenlyacross the Yankee cylinder sur-face. Tissue makers are very con-scious of that operating “sweetspot” where good quality andrunnability go hand in hand. Butas the rubber cover ages underhigh heat and various operatingpressures its hardness maychange, sometimes severely andquickly, and its crown profile maywear unevenly. That ideal operat-ing point is hard to hold over along period of time. Once the nipprofiles start to deteriorate, thiscauses quality and runnabilityproblems, leading to the removalof the roll for regrinding.

Tony Jelley, one of MetsoPaper’s sales managers for tissuemaking lines, says that tissuemakers want to extend this sweetspot for as long as possible – to120 days, and even longer. Thiswill prolong production runs andminimize the need for cover re-

grinding, thereby extending rollcover lifetimes. He sees the devel-opment of this new stable coveras very timely since the trend intissue machines is to try and usesofter pressure roll coverings, typ-ically between 35 and 42 P&Junits. He explains, “The softerrolls conform more evenly to theYankee crown. However, the soft-er covers demand even better rub-ber hardness stability in order toprovide a uniform nip widthacross the width of the machine,throughout the life of the cover.When the roll cover hardnesschanges, the crown match be-tween the Yankee and the pressureroll becomes a problem for themachine operators. Sheet profilessoon become an issue. Cross ma-chine dryness uniformity deterio-rates, creating other operationalproblems.” In addition to affect-ing sheet quality and runnability,he says that any premature coverhardness variation may decrease

Premature hardness changes and uneven cross machine direction wearing of rubber covers on tis-sue machine pressure rolls have been chronic problems for a number of years. Changes to rub-ber cover hardnesses are the result of a number of necessary operating conditions which include,but are not limited to, high temperatures, release chemicals and glues which are used to stick thesheet to the Yankee cylinder, and varying pressure roll nip loading conditions. To keep qualityand runnability within acceptable operating windows many tissue mills schedule the regrindingof pressure rolls after about 90 days of operation. In many cases pressure roll covers have hard-ened or softened even more quickly, causing cross machine sheet profiles to deteriorate. Somepressure rolls have been removed after only a few weeks of operation. In the worst cases, someroll covers have failed prematurely.

overall sheet dryness, adding todrying energy requirements.

High tech rubberThe former Beloit Manhattangroup, part of Metso Paper since2000, established a task force toaddress the chronic industry-wideproblem by developing a new rub-ber formulation. Although the ex-act details of the formulation arenaturally a closely guarded secret,the formulation and processing ofthe covering required extensiveanalytical work and, “a com-pletely new way of looking at rub-ber coverings”, according toWayne Boga, who lead the devel-opment effort. “A new method oftesting tipped it off,” he says.

The development effort wasaided with a well-equipped arse-nal of analytical tools in a labo-ratory located right next to theproduction plant. All analyticaltesting for the new product de-velopment was carried out with-in the lab.

After a short tour of that fa-cility, one realizes that rubber is ahigh technology, highly cus-tomized material. A wide range ofthermo-analysis equipment mea-sures changes in the physicalproperties and mass changes of

roll covering materials duringcontrolled or dynamic heat pro-grams. This equipment serves asa quality control tool for evalu-ating, testing and developing newpolymeric materials. For instance,dynamic mechanic thermal analy-sis equipment measures the me-chanical properties of coveringmaterials at paper machine oper-ating temperatures. These prop-erties are evaluated under bend-ing, tension, compression andshear forces.

The lab’s analytical capabilityis continually updated. For in-stance, a new infrared spectrom-eter (FT-IR) has just been added.The FT-IR, integrated with thethermo-analytical equipment,provides a powerful tool for iden-tifying the components of poly-mers. The lab also includes opti-cal and electron microscopes forevaluating surface topography.

The development program wasfast and effective because of the in-ternal testing capability and the useof matrix-based mathematicalmodels that predicted the cover’sproperties using selective designexperiments. “With these modelswe obtained the maximum amountof information in the shortest pe-riod of time,” says Boga.

The PressGator ZL productthat emerged from this facilitywas first installed on #2 tissue ma-chine at Cellu Tissue in EastHartford, CT at the end of 2000.The 130 inch trim machine makes“carrier” diaper wrapping tissuesat a speed of about 3,000 fpm.The 23.5 inch diameter watercooled, blind drilled pressure rollis loaded to 450 pli.

Better hardness and profile stabilityKevin Riley, production manager,describes the mill’s chronic strug-gles with pressure rolls: “We hadbeen dissatisfied with roll cover-ing technology for a number ofyears. We’ve had hardness andprofile stability problems and ahistory of roll cover failures. Itwas a general problem in our com-pany.”

He describes the specific prob-lems: “The covers hardened orsometimes softened by as much as10 P&J points. If the cover soft-ened the crown would wear veryquickly, in 30 or 40 days.” It wasa complicated problem to diag-nose. “Runnability and moistureprofiles would suffer for a fewweeks before we could figure itout,” he explains. “Then Valmet

(now Metso) approached with aroll covering that promised tohold its crown better and main-tain its hardness as an extra ben-efit.”

Just to be cautious, the first runtime for the newly covered rollwas limited to 90 days, the mill’shistorical “drop dead” date. Theroll was then returned to MetsoPaper factory for evaluation. Thehardness was exactly the same asthe new roll and the profileshowed very even wear across thecrown. This even wear translatesinto even pressing performance.

The mill then decided to extendthe run time to a “comfortable”cycle of 120 days. Unexpectedlyit ran for 147 days. At that timethe nip profile was still acceptableand the hardness had changed on-

ly one point. The present roll,which has been alternated withother suppliers’ rolls, has been inservice for up to 200 days with-out grinding.

The crown of the new pressureroll at Cellu Tissue showed veryeven wear after a 90-day run.

Extra value“With uniform contact at thepressure roll nip, profiles have im-proved and have been maintainedover a longer period. The crepingdoctor life is now much better,”says Riley. “We’ve extended our(nominal) grinding cycle from 90to 120 days. In addition, since theprofiles are better after a run, wehave to take off less rubber in agrind. That extends the cover’s lifefrom 4 to 6 grinds, a 50% im-provement in its life. That’s extravalue.”

Riley describes the impact oflonger roll service life on produc-tivity: “Since the market for dia-per products is good right now,less downtime (for roll changes)means more production.”

Increasing the cover thicknesswill extend the roll cover’s servicelife even further. When cover fail-ures were a problem, the roll cov-

er thickness was reduced to 3/4inch based on a supplier’s recom-mendation. Because the new cov-ers are very reliable, the coverthickness is being increased to 7/8inch. A new roll with a thickercover has been installed on themill’s #1 tissue machine. When #2tissue machine’s pressure rollneeds recovering the thicker cov-er will be ordered.

“Longer life, lower costs” atCityForestCityForest Corporation inLadysmith, WI has seen similargood results. The mill’s #4 tissuemachine was the first to use thenew cover in the summer of 2001.The machine produces jumbo tis-sue rolls. The machine’s two lay-er forming process uses virgin andrecycled fiber.

The 104 inch trim machineruns at 5,800 fpm. The 38 inchdiameter suction pressure rollruns at very high rotation speedsand is loaded to 450 pli. Widermachines running at 6,000 fpmnormally use pressure rolls withdiameters of over 50 inches.

Cliff Bienert, formerly vicepresident of operations who hassince moved to another position,

described the justification for amore stable cover material: “Ourprevious pressure rolls were hard-ening excessively and quickly, by4 or 5 P&J points over two orthree months. We have even re-moved rolls after just one month.”

He continues; “If you don’thave a perfect crown match be-tween the Yankee and the pressureroll you have non-uniform press-ing. This causes problems withprofiles, sheet blistering andrunnability.” He says that thecrown match is particularly im-portant for the 15 ft. diameterYankee that he describes as beingmechanically stiff.

He reports that the newPressGator ZL cover does notharden, it conforms better to theYankee crown and runnability isbetter. Run times have been up to157 days. With this extended pe-riod of good performance, theyhave increased the normal grind-ing cycle to 4 months. “We expectto extend it to 6 months. Thatlonger life results in lower costs,”says Bienert. Since the success on#4 tissue machine, a new blinddrilled pressure roll has been in-stalled on the mill’s #1 tissue ma-chine. �

Metso Paper Technology Days in Lahti, Finland

Metso Paper has a long tradition of arranging technology seminars forits customers worldwide. In order to fulfil Metso Paper’s aim of beingglobally local, the venue always alternates from one continent to an-other. Last year’s Technology Days took place in Shanghai China, tar-geted primarily at Asian customers.

This year was Europe’s turn,and a three-day event wasarranged in Lahti in southernFinland starting on 10 June.Altogether approximately 500people joined the seminars, heldat the famous Sibelius Hall, tolearn more about the latest trendsand developments in the field.Even though the Technology Daysevent was targeted at Europeancustomers, there were delegatesfrom 28 countries, includingmany distant countries like Iran,Venezuela and South Africa. Theslogan for this year’s TechnologyDays was “Shaping the World ofPapermaking”; with the programspecially focusing on paper and

board making technologies.Alongside the seminars, a mini ex-hibition was also arranged toshow Metso Paper’s and MetsoAutomation’s expertise in the for-est industry sector.

Program highlightsThe first day of the event was ded-icated to mill executives and spe-cialists in the field. The programof the Executive Day focused onthe importance of asset manage-ment and on Metso’s Future Careconcept, which is aimed at the lifecycle management of suppliedprocesses and equipment. Thefirst day was wrapped up with aget-together party at the Lahti Ski

Museum with the delegates arriv-ing for the main event. Lahti is fa-mous for its ski resorts and WorldChampionship games in skiing.The attendees of the get-togetherparty were also able to follow theski jumping performance, spe-cially arranged for the event.

The seminar day on Wednesday,June 11th was divided into paper-making and boardmaking sessions.In his opening words, BertelKarlstedt, President & CEO ofMetso Paper Inc., pointed out thatduring recent years both the oper-ating environment and investmentbehavior have changed greatly. In

The Executive Day was opened by Tor Bergman,President and CEO of Metso Corporation.

Metso Paper’s Executive Vice President ArtoAaltonen was the Chairman of the Executive Day.

The Papermaking session was opened by Bertel Karlstedt, President and CEO of Metso Paper, Inc.

Approximately 500 people attended the seminars at the new Sibelius Hall, in Lahti, Finland.

addition to traditional capacity in-creases through new investmentsand modernizations, improve-ments in productivity and com-petitiveness, as well as mainte-nance of the installed base, havebecome ever more important. Thishas presented challenges to MetsoPaper to offer the best possible ser-vice for its global customers.

Besides paper and board mak-ing technologies, the program al-so included a special session re-lating to Metso Paper’s FutureCare concept, entitled “Life CycleCustomer Support”. The seminarday comprised comprehensivepresentations on Metso Paper’slatest developments and the ex-perience gained by our customers,as well as presentations given byoutside specialists. As an example,the full-scope OptiConcept pa-permaking solution and solutionsfor improving the profitability ofexisting production lines were re-viewed. One example of a mill ex-perience was the new OptiSpraycoating technology at Albbruckmill in Germany, presented byLars-Hugo Olsson, Director ofTechnology.

Likewise, the latest develop-ments and experiences in the fieldwere reviewed in the boardmak-ing session. In addition to Metso’sown specialists, some visitingspeakers also gave presentationsregarding this industry sector.Nigel Jopson from PiraInternational UK presentedMicrofluting technology, Dr.Wolfgang Palm reported on thelatest developments and his expe-rience with testliner and corru-gating medium making on anOptiConcept line (in his new millin Wörth, Germany), and profes-

sor Cao Zhenlei’s paper discussedthe capacity boost in China.

The evening’s dinner party tookplace in the Forest Hall of SibeliusHall, a 13m high room with spec-tacular wooden support construc-tions and glass walls, offering amagnificent view over lakeVesijärvi. Tor Bergman, Presidentand CEO of Metso Corporation,welcomed the delegates to the din-ner and stated that the TechnologyDays seminar had brought to-gether a great number of expertsand decision-makers. In this re-gard, he proposed a toast to the

development of pulp and papertechnology and common successin the future.

The morning of the last day wasdedicated to life cycle customersupport issues, which form theessence of Metso’s Future Care con-cept. As usual, the event ended withthe opportunity to visit a referenceinstallation. This time there weretwo alternatives: PM 8 at the UPM-Kymmene Kuusankoski mill,known as the “Artti” project, forthe papermakers, and MetsoPaper’s Anjalankoski TechnologyCenters for the boardmakers.

The high interest in participat-ing in Metso Paper’s TechnologyDays is the result of considerableefforts made in the further devel-opment of pulp and paper tech-nologies. Naturally, this traditionwill continue next year, and youwill find further information onforthcoming activities in later is-sues of this magazine. �

More than 60 paper, board andtissue makers from Thailand andthe Philippines attended theMetso Paper seminar, ChallengingTechnology in Roll Services in lateMay, to learn about the most re-cent developments in roll servicesand to view first hand MetsoPaper’s Technology Center inLaem Chabang. John Della-Bosca,Business Manager of Roll Servicesand seminar chairman, welcomedthem to Pattaya, Thailand, wherea full day of technical presenta-tions was followed by a tour ofthe Technology Center the nextday.

In the opening presentation,Ari Telama, Area President, Asia-Pacific, provided a synopsis ofMetso Paper’s Roll Services. He

explained how the Valmet-Beloitmerger enabled Metso Paper tooffer a unique portfolio of state-of-the art covers for all rolls in thepapermaking process.

“Metso’s responsibility goesbeyond just providing a product,”explained Toivo Hänninen in histalk. “It extends throughout theentire papermaking process.Metso, as a producer of rolls forthe entire papermaking process,fully understands the importanceof reliable roll performance.” Henoted that rolls are made for allpositions and can be tailor-madefor all manufacturers’ machines.

Replacement rolls include thelatest innovations made for thenewest machines and the mostchallenging requirements.

BowMaster, Metso’s new com-posite spreader roll, produces aneven spreader effect to eliminatewrinkles. With the bearings out-side the roll, rather than on the in-side, it makes them easier tochange on this light and almostmaintenance free roll. The opti-mal spreader effect is achieved be-cause the direction and amount ofthe bow are adjustable.

It was the merger of BeloitManhattan into Metso that wasthe catalyst for the development ofa large number of new productsand improved know-how for rollcovers, Juhani Partanen, GlobalTechnology Manager, Roll Covers,told the gathering. “Selecting thebest practices and best productsgives the best benefit to our cus-tomers,” he said. “United MetsoCovers offer the best choices forall customer needs.” Metso’s in-novative work has resulted in newcutting-edge products such asPressJade for center rolls andPressBison for press rolls.

“Roll reconditioning and rollmodernization are two of the me-chanical roll services that are avail-able from the Laem ChabangTechnology Center,” WeeraLimjirakajorn, Product Manager,Roll Services, informed his audi-ence. “Our goal is to restore a roll’sperformance to the level it was atwhen new, and even higher. Rolls

are required to serve new needssuch as increased speed, paperquality improvements, reliable rolloperations, lower maintenancecosts and less downtime. Metsoprovides such services regardless ofwho manufactured the roll.”

Mill operations will benefitfrom Metso seminarThose at the seminar were im-pressed with what they heard.Ukrish Kanchanaketu, Director ofOperations, Kimberly-Clark Man-ufacturing (Thailand) Limited,South Mill, said, “The seminarwas very good. I learned a greatdeal about roll services and aboutwhat Metso can provide for mills.The seminar presented some ex-cellent ideas on how to improvemill operations, and each presen-tation helped me to learn more,and to better understand roll ser-vices.” At the Laem Chabangworkshop, Mr. Kanchanaketulearned the extent of Metso’s in-vestment in high technology. Hesaid it was an excellent event andhe was pleased he had attended. �

Metso Paper seminar informs customers about newand improved roll service products and technology

Polchai Jungsawat, Sales Manager, Roll Services, and Paitoon Chansuras,Supervisor, gave a guided tour of the Laem Chabang Technology Center. Thecustomers observed the rubber mixing process and got an up close and per-sonal view of the new technologies being developed at the Center.

A strong turnout of more than 60 papermaking professionals attended Metso Paper’s “Challenging Technologies in Roll Services” seminar, held inThailand in late May.

Metso’s modernization services can en-hance rolls or restore them to the samelevel they were at when new, WeeraLimjirakajorn tells the delegates.

Ukrish Kanchanaketu found he learneda great deal from the seminar and waspleased he had attended the event.

Frantschach Swiecie A.S. is one of the largest pulp and paper produc-ers in Poland and indeed in Europe. With five paper machines the an-nual production is 400,000 ADMT of kraft and NSSC pulp and 540,000tons of paper, mostly sack paper and corrugated container material.The company has been named winner of the 2003 Swedish Baltic SeaWater Award for its efforts over the last 10 years to reduce both itspollution into the Vistula River and its overall water consumption. TheVistula River drains directly into the Baltic Sea.

Two FlooBed bioreactorsoperating in seriesThe company chose to upgrade itsexisting wastewater treatmentplant with a new biological treat-ment technology. The reactorswere delivered by the formerValmet Flootek AB, later MetsoPaperChem Oy, in 1998.

The discharge, 4 kg COD(Chemical Oxygen Demand) perton of produced pulp, is now oneof the lowest in Europe and be-low the future goals for the low-er BAT values specified by theEuropean Union IPPC Bureau.

The demands have been reachedwith an advanced steering systemcontrolling two FlooBed reactors,both sized 3,000 m3, plus the ex-isting activated sludge plant op-erating in series and/or parallel.Each biological reactor is operat-ing at specific conditions to de-crease selected organic com-pounds. The Suspended CarrierBiofilm Process (SCBP), FlooBed,is an upgraded activated sludgesystem by Metso PaperChem Oy,consisting of floating carriers cov-ered with a thin biological film.

Discharge degradation in three stepsThe installation of FlooBed reac-tors was made in available processvolume at the wastewater treat-ment plant. The volume of the in-stallation is, in total, 50% of theactivated sludge reactor. WhenFlooBed was taken into operationin August 1998, the discharge ofCOD to the effluent decreased by22 tons a day. The reduction of the

wastewater treatment plant in-creased from 33% to 90% of CODand from 50 to 96% of BOD5(Biological Oxygen Demand).

Selected compounds such asCOD and color are analyzed overthe three biological steps to showthe biodegradation. In the first re-actor the wastewater is saturatedwith oxygen and most of the easi-ly biodegradable compounds arereduced. In the second reactor thedegradation of difficult to more eas-ily biodegradable components con-tinues, which is shown as BOD5.In the third reactor, the activatedsludge, the remaining biodegrad-able compounds are degraded andthe sludge quality improved.

The color of the wastewater isdark brown in the first reactor andcrystal clear when treated in thethird reactor. The process was de-scribed at the 6th IAWQ Sympos-ium on Forest Industry Waste-water (1999).

In addition to technologicalapproaches, conservation effortsenabled Frantschach Swiecie A.S.to reduce its fresh water con-sumption from 126,000 m3/d in1994 to 62,600 m3/d in 2000.

FlooBed treatment capacity 3,750 m3/hThe payback time for the invest-ment was 1.7 years based on thereduction in environmental feesfor COD discharge in 1999.

Helping the Baltic Sea torecover with FlooBedCompanies like FrantschachSwiecie A.S. are the key to im-proving the health of the BalticSea. The dramatic reduction ofpollution, in this case due to theuse of FlooBed technology, is onestep towards a healthier environ-ment in an area that has long beencharacterized as the most pollut-ed sea in the world. �

The 2003 Arne AsplundMechanical Pulping Award

The Arne Asplund Mechanical Pulping Award was established in 1985to commemorate Dr. Asplund’s contribution to the pulp and paper in-dustry worldwide. The Award is presented biennially at the InternationalMechanical Pulping Conference (IMPC). It was established to promotethe development of new technology for the manufacture of high-yieldpulp in refiners and is awarded to a person or persons in recognitionof outstanding achievement in the research and development of me-chanical pulping technology. The award consists of a gold medal andan honorarium of SEK 25,000.

Presentation of the 2003Award took place on June 3, 2003at the International MechanicalPulping Conference in QuebecCity, Canada.

The 2003 Arne Asplund AwardWinnersDr. Torbjörn Helle, Mr. Per OlavJohnsen, Dr. Kjell-Arve Kure andDr. Philip Reme have been select-ed as recipients of the 2003 ArneAsplund Mechanical PulpingAward.Dr. Helle was awarded a doctor-ate in paper physics from theNorwegian University ofTechnology in 1963 and sincethen has been associated with thatsame university. He is now a pro-fessor emeritus.

Mr. Johnsen graduated as a chem-ical engineer in Trondheim in1979 and has been associatedwith the Norwegian University ofScience and Technology NTNUand with the Norwegian Pulp andPaper Research Institute PFI inTrondheim. He is now a researchscientist with the PFI.

Dr. Kure was awarded a doctor-ate in fiber physics from the NT-NU in Trondheim in 1999. He hasbeen associated with the PFI andwith Norske Skog Research. He isnow with Norske Skog Researchas a Senior Research Scientist.

Dr. Reme was awarded a doctor-ate in fiber physics from the NT-NU in Trondheim in 2000. He hasbeen associated with the PFI andwith Norske Skog Research. Heis now a Research Director ofPaper at the PFI.

The four winners have joint-ly developed methods for thequantitative determination ofcollapsibility and the frequencyof cell wall splitting in mechan-ical pulp fibers, in particular forthe coarse fiber fraction. Thesemethods are based on ScanningElectron Microscopy in combi-nation with image analysis. Thetwo characteristics have beenshown to be of the greatest val-ue in improving the properties ofthe fiber network in papers basedon mechanical pulp fibers, espe-cially for the evenness of the pa-per surface and for its printabil-ity. The studies have demon-strated the importance of fibersplitting in minimizing surfaceroughness.

The winners’ studies have al-so made it possible to optimize theoperating conditions in differentrefiners – single as well as doubledisc – in order to achieve the high-est degree of collapsibility for thecoarse fiber fraction of mechani-cal pulps. This has been verifiedin full-scale TMP production andhas resulted in considerable ener-gy savings. �

The FoundationThe Award was made possible through a donation fromSunds Defibrator (at present Metso Paper) to the ArneAsplund Mechanical Pulping Award Foundation in 1985.The Chairman of the Board of Directors of the Foundationis Professor Emeritus Dr. Nils Hartler,The Royal Institute ofTechnology.

Ruzomberok of Slovakia orders pulp and paper mill rebuildThe Slovakian pulp and paper pro-ducer Neusiedler SCP, a.s. (formerSCP Ruzomberok, a.s.), a memberof the Neusiedler Group, is in-vesting in both production in-crease and process improvements,which will enable the mill to low-er its environmental impact.Metso Paper was awarded with acontract to carry out the requiredmodifications. One of the keytechnologies in achieving these tar-gets is Metso Paper’s high consis-tency ozone bleaching process,known as ZeTrac™. The scope ofsupply also includes the rebuild-ing of existing screening and wash-ing systems and the retrofitting ofthe single stage oxygen delignifi-cation into a two-stage OxyTrac™process. In addition, a complete

pulp bale dewiring line fromMetso Paper will be installed tomanage the increased paper millproduction.

The new equipment will pre-serve pulp quality and increaseRuzomberok’s production capac-ity from the present 900 ADT/dto approximately 1300 ADT/dwhen running hardwood. Thetwo-stage oxygen delignificationprocess will reduce both chemicalconsumption and costs, while al-so increasing yield. The ozonestage in turn will lower theamount of AOX from the bleach-ing process, thus reducing themill’s environmental impact. Thepresent bleaching sequence D-EO-D-E-D will be modified to runwith the Z-EO-DnD sequence.

New equipmentThe new screening equipment,consisting of two DeltaScreen D10units, will make up the primarystage of the brown stock screen-ing. The screen room will therebybe extended from three-stagescreening to four-stage screening,which will give a cleaner pulp aswell as being more flexible with ahigh capacity. Furthermore, fiberlosses will be reduced. The pulpconsistency in the screen roomwill be above 3%. Pulp washingenhancements will comprise aTRPB type TwinRoll™ press, tobe installed as a secondary wash-ing stage, and a TRPW type pressfor post-oxygen washing. For in-creasing the pulp consistency pri-or to the ZeTrac ozone reactor, a

TRPZ type TwinRoll press will beinstalled, enabling a pulp consis-tency of above 40%.

The bale dewiring line consistsof a conveyor system, a combineddownstacker and unit dewiringsystem, single bale dewiring(Robocoiler), a metal detector sys-tem, a Robotechnology controlsystem with remote access, engi-neering and erection supervision.The embedded software and con-trol systems in the equipment willfacilitate short erection and start-up times. The scope also includescheckout, start-up and training.

The start-up of the dewiringline will be in mid-October of thisyear, the screen room in Decemberand the bleach plant in September2004. �

Yueyang Paper starts up OptiConcept paper machine for newsprint and LWC paperYueyang Paper Group Co. Ltd.,Hunan province, China, startedup an on-line OptiConcept pa-permaking line on 1 July 2003.The new PM 8 is capable of pro-ducing either 580 tpd of high-quality newsprint or 715 tpd ofLWC paper. Metso Paper receivedthe order for the LWC line inDecember 2001.

At the start-up on July 1, themachine achieved a speed of 1280m/min at the reel. The start-up pro-ceeded normally with the OptiFeedwet-end system in particular ful-filling all expectations. MetsoPaper’s local presence ensured thatthe project progressed and stayedon schedule, even though the test-ing period was short.

The new paper machine has al-ready run newsprint in excess ofthe design capacity for a short pe-riod. The next target will be toconduct coating trials when thebase paper raw material is broughtup to the level required for LWCpaper production in the fall.

This OptiConcept paper ma-chine has a design speed of 1,600m/min and a trim width of 6.3 m.The main basis weight will be 60g/m2 and the furnish will be basedmainly on domestic poplar pulp.

The On-Line OptiConcept pa-per machine consists of an OptiFloheadbox, an OptiFormer, anOptiPress, a SymRun dryer sec-tion, an OptiHard machine calen-der, an OptiSizer film coating sys-tem, an OptiLoad calender and anOptiReel Plus. Also included area WinBelt M winder and MetsoAutomation control systems.

New deinking line andOptiFeed wet-end system The new paper machine’s stock isproduced with a new 2-loopdeinking line and an OptiFeedwet-end system, both of whichwere full scope deliveries byMetso Paper. The deinking line us-es recycled newspapers (ONP),magazine papers (OMG) and of-fice waste (MOW) as raw mater-ial. The capacity of the line is 300tons per day.

The deinking line includes all keysubprocesses, including OptiSlushdrum pulping, OptiScreen coarse,pre- and fine screening, OptiBrightmain and post-deinking flotation,cleaning, thickening, OptiFiner dis-persion, OptiBright high-consisten-cy peroxide and reductive bleach-ing, OptiThick gap washing andOptiDaf water clarification.

The OptiFeed wet-end systemof the Yueyang PM 8 covers thekey subprocesses, ranging frompulp storage towers to the papermachine’s headbox, i.e. stock lines,a broke system, stock mixing, anapproach system, wet-end chemi-cal handling and white water han-dling. Due to the swing type of pa-per machine, several different stockcomponents will be used, e.g. shortand long fiber kraft, DIP, CTMPand other mechanical pulp.

The kraft lines feature OptiSlushbale pulpers, OptiScreen coarsescreening and OptiFiner refining,followed by Kajaani KSF freenesstransmitters. The stock compo-nent proportioning and recipe isaccurately controlled in each line,and flow measurements are usedto enable fast changes in propor-tioning and to avoid level controlproblems. Metso Automation’sIQStock carries out flow infor-mation and consistency controlfor the stock lines.

The broke handling consists ofOptiSlush pulpers and a couch pit,followed by full line Gard screen-ing with OptiScreen high-consis-tency fine screens.

The approach system is a sin-gle dilution system with LobeMix,

a modern stock and chemicalmixer. An OptiAir Vac activedeaeration tank ensures effectivedeaeration. The passive aerationof OptiFormer waters with anOptiAir Flume ensures the re-quired deaeration of dilution pro-filing waters. OptiScreen machinescreening is integrated with Gardscreening to finalize the stockquality prior to the OptiFlo head-box. The save-all system is de-signed to recover fibers and to sta-bilize white water quality.

Chemical management Metso Paper’s delivery includednot only wet end chemical han-dling, but also coating colorpreparation and supply systemswith OptiScreens and OptiMixers,and coating color recovery withthe OptiFilter CR.

Wet-end chemicals and coatingcolor preparation are controlledwith the metsoDNA system, whilerecipe handling and reporting arecontrolled using FlexCom DB.The system includes two operat-ing stations located in the samecontrol room. The supply systemsare integrated with a metsoDNAprocess station, which also han-dles the OptiSizer operation. �

In Finnish,the Siberian Jay is ordinarily called ‘kuukkeli’butit has 37 other names as well, most of them referring tospruce trees.The variety of different names reflects not on-ly how widely spread and well-known Siberian Jays are allover Finland, but also how many myths relate to them.Thesame applies to Swedish as well, where the Siberian Jay iscalled ‘skogskäringen’, ‘forest witch’, and to the Germanname ‘Unglückshäher’ or ‘bringer of bad luck’.

There are several similar-looking species of Jay livingin most parts of northern Eurasia, while the other memberof the Perisoreus genus, the gray Perisoreus canadensisa.k.a. the ‘Gray Jay’or ‘Canadian Jay’, inhabit the coniferousareas of Alaska and Canada.

Young Siberian Jays may travel tens of kilometers fromtheir birthplace,but once they settle somewhere,in a small,

one square kilometer area, they usually stay for the rest oftheir lives.Typically this is a slightly swampy spruce forestwith beard lichen growing on the trees.

Siberian Jays often find their nesting place as early asmid-winter and by the latest in March/April.The nest is bigand warm, with thick walls.The number of eggs is usuallyfour, though it can vary between three and five, with thehatching period lasting approximately three weeks. TheSiberian Jay has few natural enemies, sparrow hawks pos-ing perhaps the biggest threat. Siberian Jays mainly feedtheir young insects, most of which they have stored earli-er in tree bark cracks and among lichen.

Siberian Jays are omnivorous. A Jay family roamingthrough the forest will meticulously search the entire areafrom ground level to tree tops for food, finding mainly in-

sects and spiders. In late summer, Jays feed mainly onberries and in the fall even mushrooms are added to theirdiet.Siberian Jays apparently get through winter using thefood they have gathered and stored previously.
