ABSTRACT:
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.
