ABSTRACT:
A coking process and apparatus may include cracking a hydrocarbon feed stream with a catalyst, generating a hot flue gas from regenerating said catalyst, directing the hot flue gas into a spray contactor, spraying a heavy residual oil into the spray contactor, and coking the heavy residual oil utilizing the hot flue gas as a heat source. The hydrocarbon feed stream and the heavy residual oil may each or both be generated by a solvent deasphalter. The coking process produces a solid coke product and volatile hydrocarbons which leave with the hot gas and may be burned in an oxidizer to generate steam with the pressure energy recovered by a turbo-expander.
