ABSTRACT:
An improved delayed coking process is described in which sludge and oxygen contact hot coke during the quench cycle at conditions which cause at least a portion of the organics contained in the sludge to oxidize. Preferably, a portion of the sludge is combusted and the heat generated is used to help remove, during the quench cycle, entrapped liquids contained in the coke bed and to enhance thermal conversion of hazardous materials contained in the sludge to less harmful materials.
