CO-PROCESSING OF FORD OIL RAGES WASTES AT ACC MADUKKARAIKeywords: Cement co-process , sludge , oilrages , wastes Abstract: Co-processing in cement kiln perforce privates’ high temperature and long residence condition during the operation and is effective technology foe the management of hazardous waste in an environmentally friendly and safe manner. It fully absorbs the energy and material value of the waste without any harmful emissions. Co-processing in cement kiln ranks higher in the waste management hierarchy, when compared to other disposal option such as incineration and landfill. Thus, co-processing is an ecologically sustainable solution for waste management. Ford Motor Company, an American company, manufactures and sells automobiles worldwide. Oil rages waste in their production process, which are classified as hazardous waste management rules. Considering the benefit of co-processing, ford India private Limited approaches M/S ACC limited, for safe disposal of the wastes generated by their unit, through co-processing in ACC Madukkarai cement works, Coimbatore. ACC conducted the prerequisite tests to evaluate the feasibility of co-processing the oil rages at its Technical Support Services (TSS) in thane and offered to co-process the same. The feed rate for oilrag was calculated at kiln inlet of Madukkarai cement works. During the trail burn, calculated feed rate of 40 kg per hour was maintained. At this feed rate 315 t of oilrage (packed in 1-2 kg bags) can be disposal at Madukkarai kiln every year Average the coal feed aerate (average gross calorific value of 5800 Kcal/Kg) in kiln during the trial burn was 14.50T per hour. The gross calorific value of the waste is negligible as the gross calorific vale of 6771Kcal/Kg hence the thermal substitution rate (TSR) is 0.32%.
