Abstract

A rapid adiabatic pressure swing process with a total cycle time of less than 30 seconds, at least 8 psig feed gas is introduced to a single adsorbent bed of 20-120 mesh particles and bed length not exceeding three times the feed-reverse flow pressure difference and less than 96 inches, a reverse flow period at least twice the feed gas period, and a one component enrichment factor of at least 4.
