Oxygen Generator

Principles:

N2 and O2 all have a quadrupole, for the reason that the quadrupole of N2(0.31 Å)is bigger than the quadrupole of O2 (0.10 Å), the adsorption capacity by molecular sieve to N2 is stronger than O2.  When the compressed air in certain pressure flow through adsorption bed formed by molecular sieve, the N2 gas is absorbed and O2 is obtained by separation.  

The main part of O2 generator is two towers filled with molecular sieve , when the compressed air get into adsorption tower, the N2, is absorbed by molecular sieve, O2 is produced from the export terminal . When one tower produces O2, another tower release the N2 by reducing the pressure to get the renewable desorption of carbon molecular sieve. Two towers alternate adsorption and regeneration to output O2 continuously.

 

Technical classification

According to the different pressure of adsorption and desorption, we usually divide pressure swing adsorption system into three different technology, users could choose the most suitable technology based on working conditions and requirements to achieve the purpose of reducing energy consumption .

There are usually three kinds of methods to distinguish the technology of O2 generator: PSA, VPSA, VSA.

 

Comparison of the three technology:

Model Type	PSA	VPSA	VSA
Production Flow (Nm3/h)	3~120	150~2000	2000~10000
O2 Purity (%)	91%~95%	91%~95%	91%~95%
Pressure of Export	0.2MPa~0.3MPa	18KPa~30KPa	10KPa~15KPa
Dew Point of Standard atmosphere (°C)	-45	-40	-40
Energy Consumption	0.4~0.52 KWh/Nm3 O2	0.35~0.45 KWh/Nm3 O2	0.30~0.42KWh/Nm3 O2
