Research into an asymmetric membrane hollow fiber device for oxygen enriched air production. Phase 1 final report
Oxygen enriched air combustion is a major potential energy conservation measure for American industry. Enrichment of oxygen content in air to the range of 30% to 35% during combustion benefits energy conservation in two ways. First, it leads to higher flame temperatures which in turn result in higher heat transfer rates with a concommittant reduction in process time requirements. Second, the parasitic nitrogen volume to be heated and subsequently vented at elevated temperatures is lowered. In this program a semi-permeable polymeric membrane system which overcomes the limitations of prior membrane technology has been developed for oxygen enrichment. This integral, asymmetric membrane displays both higher separation factors for oxygen to nitrogen than silicone rubber membranes while exhibiting product flowrates which result in an air separation system more economically attractive to industry. Furthermore, these membranes have been produced in the highly compact hollow fiber form which will result in the most cost-effective membrane module configuration.
