In a delayed coking process the temperature of the liquid in the coke drum (4) 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 (4), directly into the coke drum (4), or both. The resulting increase in coke drum temperature results in increased liquid yields and decrease in coke yields.

Dans un processus de cokéfaction différée, la température du liquide dans le tambour à coke (4) est augmentée par addition d'un diluant hydrocarboné chauffé sans cokéfaction. Ce diluant chauffé peut être ajouté à un effluent de four de cokéfaction différée avant qu'il n'entre dans le tambour à coke (4) et/ou directement dans ce tambour (4). L'accroissement de la température dans le tambour à coke qui en résulte entraîne des rendements en liquide accrus et des rendements en coke réduits.
