Abstract
A pressure swing adsorption (PSA) process for splitting oxygen from a feed gas comprising 95% oxygen and 5% argon to achieve an oxygen purity of at least about 99.7% is provided. A column used in the PSA process includes therein a bed of silver mordenite, an adsorbent determined to be selective to argon. In a preferred embodiment, the feed gas has a pressure of about 10.7 atm and a flow rate of about 8.8-9.2 vol. per cycle/vol of column.
