Disclosed embodiments address contaminant management challenges that arise during production of desirably contaminant free product fluid in the operation of PSA equipment, and further address the more serious challenges that arise under intermittent operation of PSA equipment. One disclosed embodiment of a PSA apparatus, intended primarily for normal operating cycle speeds of at least 3 cycles per minute, includes a breather fluidly coupled to a feed end of an adsorber with a contaminant-sensitive adsorbent. The breather can be coupled to the feed end th...
We claim: 1. A method for reducing adsorbent degradation by moisture adsorption while producing a product gas in a pressure swing adsorption process, comprising: providing a fast cycle PSA apparatus comprising adsorbers with contaminant-sensitive adsorbents having a feed end fluidly coupled to a breather through an isolation valve, the adsorbers comprising a guard material to adsorb a contaminant in a guard layer zone and a second material in an adsorbent zone to produce a product fluid by a pressure swing, the guard layer zone being isolated on shutdow...
