PROCESS FOR SEPARATING COLOUR BODIES AND/OR ASPHALTHENIC CONTAMINANTS FROM A HYDROCARBON MIXTURE

摘要

Process for separating colour bodies and/or asphalthenic contaminants from a hydrocarbon mixture using a membrane having a feed side and a permeate side, by contacting the hydrocarbon mixture with the feed side of the membrane, and by removing at the permeate side a hydrocarbon permeate having a reduced content of colour bodies and/or asphalthenic contaminants, wherein the membrane is arranged in a spirally wound membrane module.
