Abstract
VIRTUALLY ALL POLYMERIC MEMBRANES ARE MORE PERMEABLE TO OXYGEN THAN TO NITROGEN. IN CURRENT COMMERCIAL MEMBRANES THE RATIO OF OXYGEN TO NITROGEN PERMEABILITIES IS BETWEEN 2 AND 5. WITH THESE LOW SELECTIVITIES, THE HIGHEST-PURITY OXYGEN-ENRICHED AIR OBTAINABLE IN A SINGLE MEMBRANE STAGE ISABOUT 50%-AND MORE TYPICALLY, MEMBRANE PROCESSES MAKE 30 TO 35% OXYGEN. THIS PROPOSAL ADDRESSES THE DEVELOPMENT OF A NEW TYPE OF MEMBRANE THAT SHOULD EXHIBIT AN OXYGEN-OVER-NITROGEN SELECTIVITY OF AS HIGH AS 70, LEADING TO A MEMBRANE PROCESS THAT CAN PRODUCE OXYGEN AT A PURITY OFGREATER THAN 95% IN A SINGLE STAGE. FURTHERMORE, PRELIMNARYCALCULATIONS SHOW THAT FOR A 10-TON-PER-DAY PLANT, THE MEMBRANE PROCESS SHOULD PRODUCE OXYGEN AT A COST OF $10/TON COMPARED WITH A COST OF ABOUT $90/TON FOR MERCHANT OXYGEN AND $50/TON FOR OXYGEN PRODUCED VIA ABSORPTION. THE MEMBRANE TO BE DEVELOPED WILL CONSIST OF A THIN FILM OF A NOVEL INTERFACIAL POLYMER ON A MICROPOROUS SUPPORT. PHASE IIS AIMED AT PRODUCING SUCH A MEMBRANE AND DEMONSTRATING HIGHOXYGEN SELECTIVITY AND PERMEABILITY.
