PSA oxygen gas generators

How it works

• The system is using two columns with molecular sieves to ensure continuous production.

• Dry compressed air is blown through a valve to the vessel where the pressure is built to reach 5 to 7 bar(g). Nitrogen is tied to a molecular sieve during the building of pressure, and the oxygen is allowed to pass through to the accumulation tank.

• While pressure is build in one vessel, the second remains without pressure.

• A part of the produced gas is used for regeneration of the molecular sieve.

• For Oxygen, Zeolite type 13X is used. The molecular sieve is fully regenerative and has a life span on to 40.000 operation hours.

The PSA process is an extremely clean operation and the only ‘raw material’ is air.

On-site O2 generators allow an uninterrupted supply of Oxygen gas with a high purity output. This means that you can produce gas where and when you need it, and in the exact quantity and quality you need.

Meaning

PSA means Pressure Swing Adsorption

• Pressure – elevated pressures, normally 5-8Bar are needed for the process

• Swing – 2 vessels working in counterphase in terms of pressurising and depressurising

• Adsorption – The PSA principle is used for separation of atmospheric air, where product gases are separated from others by adsorption process
