VPSA oxygen system consists

VPSA oxygen system consists of a blower, a vacuum pump, the switching valve, a surge tank, and oxygen absorber composition. After the feed air intake filter to remove dust particles, is pressurized blower to 0.3-0.5barg into   activated zeolite powder 3a  which the one adsorber. Adsorber filled with an adsorbent, wherein moisture, carbon dioxide, and small amounts of other components in the gas inlet of the adsorber is loaded in the bottom of the absorption of the active alumina, and then the ASU molecular sieve sieve adsorbed nitrogen gas is filled in the upper portion of the activated alumina, zeolite molecular sieve. And the oxygen (including argon) as a non adsorbed component from the top outlet of the adsorber product gas is discharged to the oxygen surge tank.
