Vacuum Pressure Swing Adsorption (VPSA) Oxygen Generator

Vacuum Pressure Swing Adsorption (VPSA) Oxygen Generator

Technical Peremeters

Purity: 90%-93%

Capacity: 10~20000Nm3/h

Pressure: 10~25Mpa

Energy for Consumption Oxygen:0.36~0.42KWh/Nm

Working Principle

The VPSA precess is similar with PSA. VPSA oxygen generator use air blower to supply compressed air into a adsorption tower, adsorption in low pressure and adsorption in vacuum status. Under atmosphere or slightly abover atmosphere pressure, using mixed bed composed of VPSA special molecular sieve and dryer to absorb the N2,CO2.H2O and other impurities, making oxygen accumulated and collected at the end of bed .Saturation sorption of molecular sieve bed will be desorbed in vacuum status ,so as to circularly generate high purity Oxygen . (90~95%).

Compared with PSA process, VPSA has complex process equopment and higher investment but low power consumption, suitable for large scale oxygen production.
