A pressure swing adsorption air prepurifier is used to remove water, carbon dioxide and hydrocarbons from a feed gas stream, such as a feed air stream, passing to a cryogenic air separation plant. By the incorporation of a regenerative heat exchange as an integral part of the air prepurifier, the cooling effects of the desorption of water are stored and transferred so as to cool the incoming feed air stream passing to the adsorbent material within the air prepurifier. The productive capacity of the adsorbent material is enhanced thereby.
