Abstract
A process is set forth for the separation of one or more, more permeable components from one or more, less permeable components in a feed stream. The process suggests two membrane separation stages in series wherein the feed is introduced into the high pressure side of the first stage, the non-permeate stream from the first stage is introduced into the high pressure side of the second stage and wherein the permeate stream from the second stage is compressed and recycled to the low pressure side of the first stage.
