ABSTRACT:
A delayed coking process is provided in which the fresh oil is introduced into the coker product fractionator and in which a stream of heavy oil product is withdrawn from the fractionator before it can contact the fresh oil. The stream of heavy oil product withdrawn from the fractionator is subjected to solvent separation to produce a high Conradson carbon product and a low Conradson carbon product. At least a portion of the low Conradson carbon product is recovered and the high Conradson carbon product is recycled to the coking zone.
