Pervaporation process employing permeate recycle |
摘要 |
The selectivity of a membrane pervaporation aromatics/non-aromatics separation process is unexpectedly improved by the recycle of permeate to the separation process for co-processing with fresh feed. The selectivity obtained is greater than that achieved by processing either the feed or a recycle permeate stream by itself.
