COMPACT PRESSURE SWING ADSORPTION APPARATUS

摘要

Apparatus for PSA separation of a gas mixture containing a more readily adsorbed component and a less readily adsorbed component, with the more readily adsorbed component being preferentially adsorbed from the feed gas mixture by an adsorbent material under increase of pressure, so as to separate from the gas mixture a heavy product gas enriched in the more readily adsorbed component, and a light product gas enriched in the less readily adsorbed component and depleted in the more readily adsorbed component. The apparatus includes compression machinery cooperating with a number "N" of individual adsorbers or "adsorber elements" mounted in a rotary PSA module, where "N" is a factorable integer. A process for pressure swing adsorption separation is also provided.
