ABSTRACT:
A method for conditioning delayed coke includes allowing coke to form in a first chamber or coke drum, while simultaneously conditioning coke in a second coke drum by flowing through it a hydrocarbon conditioning fluid recirculated from another portion of the coking apparatus, said conditioning fluid having a temperature of more than 750.degree. F. and less than 1000.degree. F., and decoking a third coke drum. The coking, conditioning and decoding operations are sequentially switched among the coke drums.
