Abstract
A fractionated vacuum swing adsorption process previously proposed in the literature that simultaneously produces a 98% nitrogen-enriched ga s and a 90% oxygen-enriched gas from ambient air is studied by simulat ion. This process utilizes CaX zeolite as the major adsorbent and alum ina as the desiccant packed at the feed air end. In the isothermal sim ulation the feed air is considered to be a ternary mixture of nitrogen , oxygen, and water vapor, and the dynamic behavior of the adsorption bed and the effects of air humidity are studied.
