EXTRACTIVE DISTILLATION PROCESS FOR THE REDUCTION OF SULFUR SPECIES IN HYDROCARBON STREAMS

摘要

A method for separating sulfur species from hydrocarbon streams, particularly cracked naphtha streams, using extractive distillation. The method effectively separates sulfur species from cracked naphtha streams without substantially lowering the olefin content. The process involves passing a feed through inlet (12) and a solvent through inlet (14) into a distillation column (10) in order to produce a solvent bottoms which contains the sulfur species and an overhead product.
