ABSTRACT:
During delayed coking, channels are formed in the solid coke bed to facilitate cooling of the hot coke drum. A distributor device injects a fluid, preferably steam, directly into the coke drum during delayed coking. The fluid travels through the coke bed and forms a channel which eliminates an impervious zone in the mass of solid coke. The channel allows more efficient cooling of the drum and eliminates the problem of a "hot drum" which can occur during delayed coking.
