Recycling Of Tar Decanter Sludge Through The Addition Of Coke Oven Batteries In Charge Coal Feed

Toxic Tar Decanter Sludge previously dumped at the Bokaro Steel Plant, Steel Authority of India Limited (SAIL), is now recycled to the coke ovens via the coal charge. Not only has an environmental pollutant been removed but savings of US $ 0.15 million a year have resulted due to carbon recovery. Ba...

Description
Summary:Toxic Tar Decanter Sludge previously dumped at the Bokaro Steel Plant, Steel Authority of India Limited (SAIL), is now recycled to the coke ovens via the coal charge. Not only has an environmental pollutant been removed but savings of US $ 0.15 million a year have resulted due to carbon recovery. Based on encouraging results at Bokaro, other SAIL plants have undertaken the implementation of the system. This paper depicts details of the generation of tar decanter sludge, the modified recycling system, the design features, the novelty in the system, the modifications, and the economic benefits.
