1. A process for the sequential purification and fractionation of air in a single column and in the absence of pretreating the air feed to remove moisture comprising passing an air feed containing a gaseous component harmful to humans through an adsorber column to produce product effluent, said column having at least two adsorption zones, said column having a first zone comprising a feed purification adsorber for purifying an air feed and having a first adsorbent therein for adsorbing the harmful gaseous component and water vapor from said feed to effect purification, said first adsorbent capable of being regenerated, and a second zone comprising an air fractionation adsorber for adsorbing at least on component of air and having a second adsorbent therein to effect fractionation of air, said second adsorbent capabie of being regenerated, said first zone operating as a heaterless pressure-swing adsorber and said second zone operating as a purge sweep adsorber, said column being sized so that the heat of adsorption released during the adsorption of water vapor from the air feed is retained in said column and so that on application of a volume of purge gas to said column said first and second adsorbents are both regenerated, said second zone being sized so as to contain sufficient adsorbent to carry out the fractionation unaffected by the heat front generated by the heat of adsorption released in the first zone and to prevent breakthrough of the mass transfer front during fractionation, and removing the product effluent from said column.
