Conventionally, high purity O2 has been separated and recovered from air by cryogenic air separation plants. Recently, PSA (pressure swing adsorption) technology has improved and a new process is proposed to produce high purity O2 by PSA. In this technology, the removal of Ar (argon) by CMS (carbon molecular sieves) and the removal of N2 from O2 and N2 mixtures by zeolite is the key technology for the production of high purity O2. Concerning this technology, several patents for the production of high purity O2 have been issued. We have conducted a series of experiments to optimize the high purity O2 PSA process and have found an interesting result. In this paper, various factors that affect the economics of the high purity O2 generator are discussed.
