Abstract
A pressure swing adsorption process for recovery of a more readily adsorbable component, such as nitrogen, and a larger amount of a less readily adsorbable component, such as oxygen, from a feed gas mixture, such as air, wherein the ratio of nitrogen to oxygen is less than about 3:1 and the ratio of the co-purge:feed gas of the process is maintained at less than about 1.15:1.
