ABSTRACT:
A pure vacuum swing adsorption/desorption system and method, wherein supplied air feedstock gas is consistently separated to obtain a high-purity oxygen end-product gas mixture, is described. The system and method separate high-purity oxygen product from air by sequenced adsorption and desorption operations occurring exclusively under vacuum pressure conditions. This allows for greatly reduced kilowatt-hours of electric-oxygen power consumption per oxygen ton produced.
