ABSTRACT:
An improved coker fractionator system which permits withdrawing, from selected ports in the fractionator, streams of selected boiling point ranges for recovery of thermal energy and for altering the liquid vapor loading within the column for more efficient fractionation within the column. The system includes the provision of one or more ports in a fractionation column between the light coker gas oil draw and the heavy coker gas oil draw connected to either a thermal energy recovery pump-around system or a recycle system for returning a stream to the coker furnace feed stream.
