A method for argon recovery comprising (a) providing a feed gas mixture comprising argon and at least one of nitrogen and methane; (b) contacting at least a portion of the feed gas mixture with a nitrogen-selective adsorbent and/or a methane-selective adsorbent in a cyclic pressure swing adsorption process in a pressure swing adsorption system having an inlet, an outlet, and a plurality of parallel adsorber vessels, each adsorber vessel containing the nitrogen-selective adsorbent and/or the methane-selective adsorbent, the cyclic pressure swing adsorption process including adsorbing at least a portion of the nitrogen on the nitrogen-selective adsorbent in a first pressure range above atmospheric pressure to provide a purified argon product and an adsorbent comprising adsorbed nitrogen and/or adsorbing at least a portion of the methane on the methane-selective adsorbent in the first pressure range above atmospheric pressure to provide a purified argon product and an adsorbent comprising adsorbed methane; (c) and desorbing the adsorbed nitrogen and/or the adsorbed methane in one or more regeneration steps effected in a second pressure range between atmospheric pressure and a super-atmospheric pressure below any pressure in the first pressure range, inclusive; (d) wherein the cyclic pressure swing adsorption process is effected at an average operating temperature of at least 0°C and between a super-atmospheric maximum pressure and a minimum pressure; characterized in that (e) the method further comprises depressurization and gas transfer from one of the adsorber vessels to purge another one of the adsorber vessels at or above atmospheric pressure; and (f) the minimum pressure is equal to or greater than atmospheric pressure.
