PROCESS FOR DEHYDRATION OF GASES AND COMPOSITE PERMEABLE MEMBRANES THEREFOR

摘要

PROCESS FOR DEHYDRATION OF GASES AND COMPOSITE PERMEABLE MEMBRANES THEREFOR of the Invention Process for the dehydration of gases using composite permeable membranes, preferably hollow fiber composite membranes comprised of a porous support coated with an ultrathin layer of a defined sulfonated polysulfone or sulfonated polyether ketone. The processes also contemplate the use of a sweep or purge gas on the water-enriched permeate side of the composite membrane to increase the efficiency of the dehydration process.
