3.0 NEED FOR USE OF PET COKE

Due to uncertainty in the availability of coal linkage and rising pricesof imported coal, it is proposed to use fuel mix of pet coke and Coal forwhich approval from MoEF&CC is being sought. The proposed fuel,i.e. Pet Coke is readily available in Indian market. For the above CPP,the conversion to pet coke as an alternative fuel is envisaged due tothe following reasons:

1) Petroleum coke (Pet coke) is a carbonaceous solid derived from oilrefinery coker units or other cracking processes. The chemicalcomposition of petroleum coke is mostly elementary Carbon (usuallyover the 85% C (dry) with sulphur content of about 6.0 % (max)) withhigh heating value and very little ash content (usually less than 1-2%).

2) Compared to other low ash coals, pet coke has advantage in terms ofbed material inventory. In spite of having low ash content, the bedmaterial requirement is minimum, since limestone and its reactedproducts (gypsum) act as the bed material.

4.0 ENVIRONMENTAL BENEFITS OF USAGE OF PETCOKE

The pet coke based captive power plant will ensure supply ofcaptivepower at a competitive cost, providing greater flexibility andviability to the ACC Manufacturing operations in an environmentallyresponsive manner.

The project will result in following environmental and economicbenefits:

1) Generation of power at a competitive cost compared to power generatedby using imported coal.

2) Utilization of industrial waste thus resulting in fossil fuel conservation.3) Limestone injection in Boiler will greatly minimize SO2 emission from the

stack (>80 % reduction and to meet new environmental norms of <600mg/Nm3).

4) Solid wastes viz. Fly Ash and Bottom Ash generated from the CPP will bereused/ recycled in the cement plant located within the premises.

5.0 PROJECT COST

No additional project cost is involved.

6.0 PROJECT DESCRIPTION:

Jamul Cement Works is a fully integrated cement plant supportedwith captive power plant and captive mining of limestone.

JCW has obtained Environmental Clearance from MOEF&CC for usingpet coke in the Kiln. Due to non availability of coal, it is now proposed

to use fuel mix of pet coke and coal in CPP in addition to coal. The petcoke is proposed to be brought to site by rail/ road. In case of roadtransport, pet coke will be brought in high capacity covered trucks toavoid spillage.

6.1 CAPTIVE POWER PLANT

To increase the thermal efficiency, a pre-heater for the fluidizing airand combustion air, and a boiler feed water heater, are installed SO2

emission is reduced by injection of limestone in the combustionchamber.

Limestone Feed and Control Mechanism

Sulphur capture in boiler happens by injecting Limestone along withfuel. The fuel and Lime mixture enters into combustion chamberthrough multiple feed points located in furnace front close to thebottom primary zone. Limestone undergoes decomposition by takingheat from the hot bed material (endothermic) and converts intoCalcium Oxide (CaO).This process is called Calcination. The calcinedLimestone being porous in nature gets entrained in flue gas andenters the top section of furnace where the mixture of Oxygen andSulphur Dioxide reacts with Calcium Oxide and converts into CalciumSulfate (CaSO4).This Process is called Sulfation. This process is anexothermic reaction. Thus, the Limestone converts gaseous SO2

emission to solid Calcium Sulfate and gets removed from the system.Attributing higher particle residence time and recirculation, theSulphur capture efficiency in boilers can be achieved to almost 80 %.The amount of limestone that is required for a given amount of fuelmix depends on the sulphur content . An increase in sulphur dioxideemissions will necessitate an increase in the amount of limestone thatis required for a given fuel flow to the furnace. The limestone demandis a function of the main fuel flow. An increase in fuel flow demandwill result in a corresponding increase in the limestone demand toprovide the demand signal to the Limestone Variable Rotary Feeder.

The limestone requirement is about 0.012 million TPA

7.0 FUEL-REQUIREMENT, QUALITY AVAILABILITY &TRANSPORTATION:

It is envisaged that pet coke required for the project will betransported through rail/ road. During road transport pet coke will bebrought in closed trucks. Limestone available inside the plant will beused.

PET COKE QUANTITY:

Considering pet coke with gross calorific value (GCV) of 8000 kcal/kgand coal GCV of 3500 kCal/kg) and plant load factor of 100%, theannual fuel mix requirement proposed is 58 % heat input throughcoal and 42 % heat input through pet coke. For fuel mix, Coalrequirement will be 0.109 million TPA and Pet coke requirement willbe about 0.034 million TPA.

FUEL QUALITY (PET COKE):

Pet coke for the project will be available either from Indianrefineries/imported. During road transport, pet coke will be broughtin high capacity covered trucks.

The proximate and ultimate analysis of pet coke to be used for thecaptive power plant are as follows:

Heating ValuesCalorific Value 8000 kcal/kgUltimate Analysis (weight %)Moisture 4.50Ash 0.84Carbon 79.00Hydrogen 3.21Nitrogen 1.37Sulphur 6.0Oxygen 1.69Proximate Analysis (weight %)Moisture 4.5Ash 0.84Volatile Matter 10.60Fixed Carbon 80.30Source :ACC Ltd

Because of the extremely low ash (<1%) and high sulphur content ofpet coke (6.0%), limestone is used in the majority of bed materials ofthe fluidized boilers using pet coke. Limestone sizing is critical notonly for efficient sulphurcapture but also for effective fluidization andfuel mixing thereby uniform temperatures and heat transfer isattained. Limestone will be sourced from the captive mine situatedadjacent to the cement plant. Limestone of approx. 45% CaO contentwill be used for CPP for desulphurization.

PET COKE HANDLING PLANT:

The pet coke handling will be done in the same system designed forcoal.

CONTROL OF PARTICULATE MATTER

Captive Power plant:Due to the very low ash content in fuel mixcompared to coal, there will be low particulate matter emission inpower plant and the outlet emissions will be well below 50 mg/Nm3

CONTROL OF SULPHUR DIOXIDE

Fluidised Bed Combustion technology ensures complete combustionof the low volatile pet coke. The technology also captures a largeamount of Pet Coke's sulphur during the combustion process. Thevigorous mixing of the fuel, limestone and ash particles during thelow-temperature fluidized process allows to cleanly and efficientlyburn almost any combustible material, while minimizing the formationof NOx and optimising the capture of SO2 as the fuel burns.

CONTROL OF OXIDES OF NITROGEN

Nox emissions are low in FBC boilers and additionally, to reduce NOxto an extent of 20 %, process optimization and use of Biomass will bedone.

8.2SOLID WASTE GENERATION

The maximum expected quantities of Ash generated is 210.60 tpdwhen 100 % coal is fired. Maximum ash generation from fuel mix is

151.72 tpd(from fuel ash and limestone injection). Only dry ashhandling system is adoptedand the ash is stored in silos.Transportation of Ash in dry form from the hoppers to storage silos isdone through pneumatic conveying. 100% ash will be utilized formanufacturing of Portland Pozzolana Cement (PPC). The bottom ash ofFBC boilers will have minimum unburnt carbon and thus will be usedin cement raw mix.

9.0 CONCLUSION

ACC – JCW proposes to obtain Amendment in EC for use of fuel mixof coal and petcoke in addition to coal as alternative fuel in captivepowerplant.

Use of Petcoke in the cement industry results in variousenvironmental benefits listed below

1) Generation of power at a competitive cost compared to powergenerated by using imported coal.

2) Utilization of industrial waste thus resulting in fossil fuelconservation.

3) Limestone injection in Boiler will greatly minimize SO2 emissionfrom the stack (>80 % reduction and to meet new environmentalnorms of <600 mg/Nm3).

4) Solid wastes viz. Fly Ash and Bottom Ash generated from theCPP will be reused/ recycled in the cement plant located withinthe premises.

5) Lowering CO2 emissions

FBC technology adopted enables use of fuel mix in the boiler andinjection of limestone which controls the sulphur dioxide emission by80 % meeting outlet concentration of 600 mg/Nm3.

NOx emissions are low in FBC boilers and additionally, to reduce NOx toan extent of 20 %, process optimization and use of Biomass will be done.

There will be decrease in pollution load with fuel mix usage as limeinjection in boiler is proposed for capturing the sulphur dioxide.
