ABSTRACT:
In a delayed coking process the temperature of the liquid in the coke drum is increased by the addition of a heated non-coking hydrocarbon diluent. The heated non-coking diluent can be added to either a delayed coker furnace effluent prior to entering the coke drum, directly into the coke drum, or both. The resulting increase in coke drum temperature results in increased liquid yields and a decrease in coke yields.
