초록

Membrane permeation processes to produce oxygen-enriched gas from atmospheric air are improved by initially contacting an ambient air feed with triethanolamine to substantially reduce the nitrogen dioxide content in the air and thereafter feeding the nitrogen dioxide depleted air to an array of membrane cells and finally withdrawing the oxygen-enriched permeate output therefrom, substantially free of nitrogen dioxide, for further use.

청구항

In a membrane permeation process to produce oxygen-enriched gas from atmospheric air comprising delivering a flow of atmospheric air feed to an array of selectively permeable membrane cells having a greater permeability of oxygen and nitrogen dioxide relative to nitrogen and maintaining a pressure differential across said array to produce an oxygen-enriched permeate therethrough, the improvement for reducing the nitrogen dioxide content in said permeate to substantially nil comprising: i. initially passing the atmospheric air feed containing at least an ...
