MEMBRANE PROCESS FOR SEPARATING SULFUR COMPOUNDS FROM FCC LIGHT NAPHTHA
摘要
A process for the separation of sulfur compounds from a hydrocarbon mixture using a membrane is provided. Preferred hydrocarbon mixtures are oil refining fractions such as light cracked naphtha. Membranes are composed of either ionic or non-ionic materials andpreferentially permeate sulfur compounds over other hydrocarbons.A single or multi-stage membrane system separates the hydrocarbon mixture into a sulfur-rich fraction and a sulfur-lean fraction. The sulfur-lean fraction may be used in fuel mixtures and the sulfur-rich fraction may be further treated for sulfur reduction.
