Energy efficient production of oxygen-enriched air through use of newly developed liquid membranes is reported. The facilitated-transport membranes developed at Bend Research consist of a liquid membrane containing a dissolved oxygen carrier held by capillarity within the pores of a microporous, polymeric membrane support. The key to this development has been the discovery of liquid membranes that exhibit high oxygen permeability, high oxygen-to-nitrogen selectivity, and stable membrane performance. The most selective membrane allowed production of 88% oxygen in a single pass through the membrane.
