PROCESS FOR SEPARATING A FEED STREAM GAS MIXTURE USING PRESSURE SWING ADSORPTION

A molecular sieve, pressure swing adsorption process employing two adsorbers for generating an enriched gas from a feed stream gas mixture is claimed, wherein each adsorber repeatedly passes through sequential steps comprising: (a) high pressure adsorption; (b) cocurrent partial depressurization by...

Beschreibung
Zusammenfassung:	A molecular sieve, pressure swing adsorption process employing two adsorbers for generating an enriched gas from a feed stream gas mixture is claimed, wherein each adsorber repeatedly passes through sequential steps comprising: (a) high pressure adsorption; (b) cocurrent partial depressurization by pressure equalization; (c) countercurrent venting to atmosphere; (d) regeneration using a product gas purge; (e) partial repressurization using product gas; (f) cocurrent partial repressurization by pressure equalization; and (g) feed gas repressurization to the adsorption pressure.
