The VPSA Oxygen Plant System has great advantages in the field of oxygen production ≥ 150Nm3/h. It has a wide range of applications and can be used in oxygen production from 150Nm3/h to 80000Nm3/h. The VPSA is fed into the molecular sieve adsorption purifier by the air booster blower at normal pressure (50KPa), because the air enters at normal pressure, the air will be evenly distributed, the molecular sieve has high utilization efficiency, good adsorption effect, high oxygen extraction rate, and good oxygen purity. Therefore, when the oxygen production required is greater than 150Nm3/h, the VPSA process can save a lot of energy than PSA.

When the oxygen production volume is less than or equal to 100Nm3/h, the PSA oxygen production equipment has great advantages for it’s small size, easy operation, and energy saving; but when the oxygen production volume is greater than 100Nm3/h, especially when the oxygen production volume is more than 150Nm3/h, PSA oxygen generator process is not suitable，At this time you need to use the VPSA Oxygen Plant System.
