Adsorption Technology for Air Separation

摘要

PVSA (pressure vacuum swing adsorption) process, combining equilibrium separation with kinetic separation, was developed to air separation in the adsorption process. A PVSA process with two equilibrium beds and one kinetic bed was developed to overcome the limitation of 94% O2 purity from air in the adsorption technology. From PVSA processes, up to 99+% O2 from air could be produced.
