ABSTRACT:
In an adsorption-desorption process for separating gaseous mixtures comprising passing a stream of crude gaseous mixture under superatmospheric pressure through a first adsorber, withdrawing from said first adsorber a stream of product gas depleted in undesired component; switching the stream of crude gaseous mixture to a second adsorber when the impurity concentration at a given location before the exhaust end of the first adsorber exceeds a given value in the gas; after the crude gas stream is switched away from said first adsorber, decompressing said first adsorber in at least one decompression stage to release residual product gas therefrom; and employing said residual product gas to re-pressurize an adsorber, the improvement which comprises conducting said decompressing in at least two separate decompression stages, collecting the residual product gas from each decompression stage in separate storage vessels, withdrawing residual product gas from one storage vessel and purging the decompressed adsorber to desorb undesired impurities therefrom, and withdrawing residual product gas from another of said storage vessels and partially re-pressurizing the purged adsorber therewith.
