ABSTRACT:
A delayed coking process is provided in which the fresh hydrocarbonaceous oil feed is divided into at least two streams. One stream is introduced directly into the preheating zone of the coking zone and one stream is introduced into the coker product fractionator. The fractionator bottoms fraction is recycled to the preheating zone as a separate stream from the fresh feed stream. The separate preheated fresh feed stream is introduced into the top of the coking zone and the preheated recycled fractionator bottoms fraction is introduced into the bottom of the coking zone. The given fresh feed splitting configuration permits decreasing the recycle rate of the heavy coker product and increasing liquid yield while the top and bottom feeding to the coking zone permit subjecting the given streams to different severity of coking.
