Abstract
A hydrocarbonaceous oil is introduced to a quench and scrubbing zone mounted on a fluid coking reactor. Heat from the coker vapor product vaporizes a portion of the hydrocarbonaceous oil. The unvaporized portion of the oil is used to quench and scrub the coker vapor product. The bottoms fraction of the quench and scrubbing zone is passed to a vacuum distillation zone to recover a heavy oil fraction and to produce a vacuum residuum for use as coker feed.
