VPSA oxygen plants


Features

VPSA means Vacuum Pressure Swing Adsorption. Feed air is sucked filters for removal of dust before boosted to 0.3~0.5barg by roots blower. It then goes into an absorber full of absorbent activated aluminum to eliminate water, CO2 and other gases at the bottom, above which N2 absorbed by absorbent zeolite molecular sieve. O2 with argon is output on the top as product gas into oxygen buffer tank and then boosted to higher pressure by oxygen compressor to consumption point.

Product Details


VPSA means Vacuum Pressure Swing Adsorption. Feed air is sucked filters for removal of dust before boosted to 0.3~0.5barg by roots blower. It then goes into an absorber full of absorbent activated aluminum to eliminate water, CO2 and other gases at the bottom, above which N2 absorbed by absorbent zeolite molecular sieve. O2 with argon is output on the top as product gas into oxygen buffer tank and then boosted to higher pressure by oxygen compressor to consumption point. 

 

When the absorbents are at saturation state full of absorbed gases, it is depressurized to negative micro-pressure before vacuumized by vacuum pump to -0.5~-0.8barg. Then the air of the other absorber and some product gas will be let in to push absorbed water, CO2, N2 to atmosphere. The absorbent is regenerated. The other absorber is like this, again and again. 

 

VPSA or VSA oxygen generation plant has similar working principle to PSA method. They both uses the characteristics of adsorbent molecular sieve to separate nitrogen and get oxygen. The difference is PSA has pressurized adsorption (0.2~0.6Mpa), atmospheric desorption. And VPSA has adsorption under atmosphere or slightly above atmospheric pressure (0 ~ 50Kpa), vacuum pump desorption (-50 ~ -80Kpa).
