PRODUCTION AND REMOVAL OF FREE-FLOWING COKE FROM DELAYED COKER DRUM

摘要

A method for producing and removing coke which has bulk morphology such that at least 30 volume percent is free-flowing under the force of gravity or hydrostatic forces from a delayed coker drum. At the completion of the fíll cycle, the coker drum, filled with hot coke, is cooled by steaming and then flooding it with water, thereby producing a coke/water mixture. The coke/water mixture is released from the coke drum through one or more drum closure/discharge throttling systems near the bottom of the coker drum.
