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.
What’s the difference between PSA Oxygen Generator and VPSA Oxygen Generator?
Pressure Swing Adsorption Oxygen Generator is widely used in various fields, such as the Paper and Pulp industries, Glass
industries, Metallurgical industries, Chemical industries, Water and Wastewater treatment, Fish farming and so on. But what’s the
difference between PSA and VPSA oxygen generator? Generally speaking, if you need the oxygen in large capacity, VPSA oxygen
generator is more fit for you, of course the cost is higher.
Here is listed their difference in many aspects.
