INTEGRATED SOLVENT EXTRACTION/MEMBRANE EXTRACTION WITH RETENTATE RECYCLE FOR IMPROVED RAFFINATE YIELD

摘要

it enhances the production of the raffinate from the extraction solvent, when submitting the extract (5) recovered from the solvent extraction process, (2) a stage of membrane separation (6) which produces a retentat (8) rich in monocyclic aromatic compounds / satur (7) and a permeate which is rich in aromatic bicyclic or pluricycliques.and we are retentant phase rich in monocyclic aromatic / unsaturated compounds in the process of solvent extraction.
