As premium-grade hydrocarbon feed-stocks prices rise, synfuels and novelpetrochemical processes are becom-ing increasingly valuable. Natural gasrepresents an abundant alternativehydrocarbon source to crude oil. It isdistributed throughout the world andrepresents a cleaner fuel compared tocrude oil.Therefore, the method of convertingnatural gas to marketable liquidhydrocarbons (GTL) gets increasinginterest worldwide. Large plants have

been erected and are in the designphase with a tremendous need in pro-cess instrumentation including pro-cess analyzer systems.

Siemens, a leader in process analyticalinstrumentation, has proven overdecades its capability to plan, engi-neer, manufacture, implement andservice such analyzer systems.

This Case Studyprovides details aboutthe GTL process and related analyzertasks.

NG, FT and GTLNatural Gas (NG) is a vital compo-nent of the world's supply of energy.It is one of the cleanest, safest, andmost useful of all energy sources.NG is colorless, shapeless, and odor-less in its pure form. It is combusti-ble, and when burned it emits lowerlevels of potentially harmful by-products into the air than otherfuels. NG is a mixture of hydrocar-bon gases. While it is formed prima-rily of methane, it can also includeethane, propane, butane, pentaneand certain impurities. NG has beenwidely used to make commodityproducts such as methanol orammonia. But in light of environ-mental and economic climate todayits conversion to synthetic liquidhydrocarbons has become a mostimportant objective worldwide.

It was already in 1923, whenFischer and Tropsch (FT) developedthe process of converting coal into

syngas and from there into gaso-line. But it took many decades fromthis FT-process origin before the firstcommercial FT-based plant, usingNG instead of coal, was put intooperation. Meanwhile, new technol-ogies have been and are beingdeveloped to convert NG to liquids inGas-to-Liquid (GTL) processes.Commercial interest in using thesenew technologies arise from e.g.increasing consumer demand forcleaner burning fuels or from the

opportunity to develop gas reservesremote from existing markets.

Consequently, many GTL plants existtoday, are under development or indesign phase using different FT-pro-cess technologies (Sasol, Shell,Exxon, e.a.). Whatever technology isapplied, the process steps requirealways to be monitored and con-trolled continuously.Process analyzers play an importantrole for that. Hundreds of processanalyzers, most of them process gaschromatographs, are in use in atypical GTL plant.

The GTL process at a glance

Process chainThe GTL process chain consists of anumber of fundamental processingsteps each of which is important toachieve the final goal of producing highquality synthetic liquid hydrocarbons.The Fischer-Tropsch (FT) reaction isconsidered the heart of the process-chain. Its overall efficiency dependsstrongly on the type of reactor technol-ogy used as well as on the catalystmaterial applied.

The three main process steps and asso-

ciated utilities include (Fig. 1):Syngas generationSyngas (Synthesis gas) is composed ofhydrogen (H2), carbon monoxide (CO)and carbon dioxide (CO2), whereas theration H2/CO is important in view of theprocess efficiency using a certain cata-lyst material. Syngas is produced fromnatural gas (NG) through a reformingprocess. Various technologies are usedfor that, with or without air or oxygen,such as Steam Methane Reforming(SMR), Partial Oxidation (POX),Autothermal Reforming (ATR), e.a.

Syngas conversionThe conversion of syngas to hydrocar-bons comprises the process of H2 andCO molecules to form -CH2- alkyl radi-cals and water in an exothermic reac-tion. The -CH2- radicals then immedi-ately combine in a preferably iron orcobalt based catalytic reaction to makesynthetic olefin and/or paraffin hydro-carbons of various chain-lengths (highboiling point wax and olefinic naphta).This process is called the Fischer-Tropsch (FT) synthesis process.

Synthesis product upgradingThe longer straight-chain paraffins arepure solid waxes at room temperaturewith a limited market only. Therefore,to obtain a better usable scope of hydro-carbons, the waxy paraffins need to beupgraded to recieve products withshorter chain length and lower boilingpoints. This is realized through e.g. cat-alytic hydrocracking of the wax streamsand hydrotreating of the naphta.

Utilities and by-product treatmentUtilities are pieces of equipment to pro-vide services such as heat or electricitynecessary to fulfill the plants main goal.

By-products of the FT-process are the

FT-tail gas and the FT water each ofwhich is treated in order to improveplant efficiency.

Various technologiesVarious technologies have been devel-oped and are implemented worldwidein GTL plants:

Sasol has developed various reactortypes with the slurry phase distillateprocess being the most recent.

Statoil uses a slurry reactor in whichsyngas is fed to a suspension of cata-lyst particles in a hydrocarbon slurrywhich is a product of the processitself.

The Shell Middle Destillate Synthesis(SMDS) process focuses on maximis-ing yields of middle distillates such askerosene and gas oil.

Exxon uses a slurry design reactor andpropietary catalyst system. The pro-cess can be adjusted to produce arange of products.

Rentech uses a molten wax slurryreactor and a precipitaded ironcatalyst.

Syngas generation (ctd.)Syngas conversion (FT Synthesis)

FT SynthesisIn the FT Synthesis, synthesis gas is con-verted into liquid hydrocarbon chainsbased on the famous FT Chemistry.In the chain growth reaction a widescope of products is formed ranging

from very light to heavy paraffins.The most important element of thisreaction is the type of catalyst used.Two predominant formulations are inuse, one based on iron and the other oncobalt. Both feature advantages and dis-advantages and differ, amongst others,in their suitability with respect to feedcomposition and desired product scope.

Besides the catalyst, the design andoperation principle of the conversionreactor is another key element. Varioustypes of FT reactor systems are in use,which have in common the need to

remove the exothermic heat of thereaction. But they show also fundamen-tal differences.

Fixed bed reactorThis is a reactor that uses a catalystpacked in vertical tubes surrounded bya coolant medium and arranged in avertical vessel. The syngas flows down-wards through the tubes and heatis removed through the tube wallsto produce steam.

Fluidized bed reactorIn fluidized bed reactors, the gas isblown up through the solid catalyst par-ticles causing them to lift and separate.Thus the particles are fluidized and thegas is converted by passing the fluidized

bed of catalyst particles. Heat transfercoils within the reactor remove the heatand generate steam.

Slurry reactorA slurry reactor contains a slurry of mol-ten wax and FT liquid products with thepowdered catalyst dispersed through it.The syngas is bubbled through this mix-ture and thus converted. Heat is recov-ered via cooling coils, which generatesteam.

Process analysis in FT SynthesisA great number of process analyzers are

used in the FT synthesis section.Details will differ from plant to plantdepending on process technlogy andplant design. Therefore, Fig. 4 andTable 2 show typical measuring pointlocations and typical measuring tasks.

Product Upgrade and By-product Treatment

Product UpgradeConventional refinery processes can beused for upgrading of FT liquid and waxproducts such as fractionation,hydroc-racking, isomerization, hydrotreatingetc. (Fig. 4).Final products from FT synthesis are ofhigh quality due to a very low aromaticsand almost zero sulfur content.

Primary separationPrimary separation occurs alreadywithin the FT block (Fig. 4) and basically

separates from each other the straight-run synthetic

hydrocarbon FT liquid streams.

the non-converted FT tail gas,

the FT water streams,

the molten wax stream

Hydrocracking/Isomerization (HCI)Hydrocracking is preferably used to con-vert the wax into lighter distillates withshorter chain length and lower boilingpoints. It uses fixed-bed reactors andsuitable catalysts. Hydrogen is suppliedeither with PSA purity or as pure hydro-

gen made from a slip stream of syngas.HydrogenationHydrogenation is applied to the naphtato saturate straight-run productstreams.

FractionationLiquid effluent from the hydrocrack-ing/isomerizaton block is heated andthen distilled. The separate products arewithdrawn, cooled and sent to theirstorage tanks.

By-producttreatment

FT Tail GasFT tail gas representsunconverted reactantsand light hydrocarbonswhich are normallyrecycled to the syngasgeneration section.However, this is possi-ble only to a certainlimit due to the pres-

ence and build-up ofgases such as Nitrogenand Argon. Therefore,the tailgas is partlypurged out of the sys-tem and possibly usedfor combustion e.g. ina gas turbine. In theextreme case no recy-cle is possible and all tail gas is purged.

The tail gas contains components suchas hydrogen, water, methane, carbonmonoxide, carbon dioxide, nitrogenargon, and heavier hydrocarbons.

Typically hydrogen is removed from thetail gas for further use by a PSA (Pres-sure Swing Absorber).

FT Synthetic WaterFT synthetic water is co-produced andneed to be removed from the reactor.Some of the contained components canbe recycled to the syngas generationsection, while other must be removed

by a special water treatment procedure(stripping by steam, removing bymechanical means, converting throughbiological measures).

Process analysis in product upgradeand by-product treatment

A great number of process analyzers areused in the product upgrade and by-product treatment section. Details willdiffer from plant to plant depending onprocess technlogy and plant design.

Utilities

Steam and oxygenUtilities are pieces of equipment to pro-vide services such as heat or electricitynecessary to fulfill the plants main goal.

Syngas generation requires, dependingon the technology, steam, compressedair, and oxygen.While steam production simply requiresa fired boiler, the production of oxygenis a more complex process. Large-scaleoxygen production uses cryogenic airseparation processes, which rely on dif-

ferences in boiling points to separateand purify products. Cryogenic air sepa-ration plants are referred to as an AirSeparation Unit (ASU) or Oxygen Plant.

Numerous different process configura-tions are in use, but all of them includethe following steps Fig. 5):

Filtering and compressing air

Removing contaminants, includingwater vapor and carbon dioxide(which would freeze in the process)

Cooling the air to very low tempera-ture through heat exchange andrefrigeration processes

Distilling the partially-condensed airto produce desired products

Warming gaseous products and wastestreams in heat exchangers that alsocool the incoming air

The units of the ASU that operate at verylow temperatures (distillation columns,heat exchangers and cold interconnect-ing piping sections) must be well insu-lated to minimize energy consumption.Therefore, these components arelocated inside insulated "cold boxes.

Fig. 5 and Table 3 present typical mea-

suring point locations and related mea-suring tasks in a ASU.

Prozess analytics at Utilities

For steam generation units, typically,analyzers are used to optimize the com-bustion process (O2)as well as to moni-tor the flue gas for polluting compo-nents (SO2, NOx, ...) according to thelocal regulations.

At air separation plants numerous ana-lyzer are used. Fig. 5 and Table 3 displaytypical measuring point locations andrelated measuring tasks.
