Abstract:
1. A displacement purge gas separation process for separating a first component from a second component of a feed gas mixture where the second component is more readily adsorbed by an adsorbent material in a displacement purge gas separation apparatus having plural adsorbers, each adsorber having a flow path in contact with an adsorbent material between a first and a second end, the process comprising: supplying a feed gas mixture comprising at least the first component and the second component to the first end of the first adsorber; withdrawing a product gas enriched in the first component from the second end of the first adsorber; supplying a first buffer gas substantially free of the first component to the first adsorber to substantially displace any remaining first component from the internal space of the first adsorber; and supplying a less-readily adsorbed purge gas to the first adsorber to substantially desorb adsorbed second component from the adsorbent material.
