Olefin/paraffin separation via membrane extraction |
摘要 |
Olefins are selectively separated from hydrocarbon feeds containing mixtures of olefins and paraffins by contacting said hydrocarbon feed mixture with one side of a micro-porous, non-selective partition barrier membrane while simultaneously passing, preferably in countercurrent flow, along the opposite side of said membrane a polar solvent. The olefin preferentially passes through said micro-porous non selective partition barrier in response to the polar solvent yielding a permeate enriched in olefin and a retentate enriched in paraffin as compared to the original feed stream.
