Claim:
A process for producing a solid petroleum coke product in a delayed coking system, said delayed coking system including a plurality of coking drums with said process comprising: each of said coking drums operating in alternating delayed coking cycles including a fill cycle followed by a second cycle, wherein during said fill cycle a drum feed material is delivered into said coking drum to form said solid petroleum coke product therein and produce a vapor product which is delivered to a product fractionator, wherein said drum feed material is not delivered into said coking drum when said coking drum is operating in said second cycle, said solid petroleum coke product is not removed from said coking drum when said coking drum is operating in said fill cycle, and said process further comprising the step in said second cycle of removing from said coking drum said solid petroleum coke product which has been formed in said coking drum without quenching said solid petroleum coke product with water or other quenching liquid in said coking drum and without cutting said solid petroleum coke product in said coking drum such that, when removed from said coking drum in said step of removing, said solid petroleum coke product is a flowable material which flows out of said coking drum in solid form.
