Abstract
The present invention relates to a process cycle that allows for the stable production of mid-range purity oxygen from air, using traditional system designs. Typical cycles have a limited production benefit when generating O2 at lower than 90% purity, however they suffer a production loss at higher purity. The process cycles of the invention are capable of producing significantly more contained O2 at a lower purity. In addition to enhanced production capacity, lower power consumed per mass of product and more stable product purity and flow are realized by the process of the invention compared to traditional alternatives.
