PROCESS AND APPARATUS FOR HYDROCRACKING WITH PREFRACTIONATOR FOR STRIPPED STREAMS

摘要

A process and apparatus for hydrocracking a hydrocarbon stream that feeds a cold stripped stream and a hot stripped stream to a prefractionator from which a prefractionated overhead stream and a prefractionated bottoms stream are passed to a product fractionation column. The product fractionation column may produce three products, light naphtha, heavy naphtha and distillate omitting the need for a naphtha splitter column. Data may be received from a stream in fluid communication with the foregoing process and apparatus.
