ABSTRACT:
The present invention is a process for separating and recovering a component from a multi-component feed gas mixture. The feed gas mixture is initially separated in a membrane separation unit or units to produce a gas stream concentrated in the desired component. The concentrated gas stream is subsequently further separated in an adsorption unit having an adsorbent which selectively adsorbs non-desired gaseous components thereby producing a purified product stream. The non-desired gaseous components are subsequently desorbed and a purge stream from the adsorption unit containing the desorbed non-desired gaseous components along with a portion of the desired components is recycled to the feed gas mixture.
