PSA oxygen technology

Pressure swing adsorption (PSA) oxygen

What is PSA oxygen?

PSA is short for: Pressure Swing Adsorption

Pressure
Elevated pressures are needed for the process, usually 4-8 bar(g). In case a higher pressure is required for your process, this can be applied, too.

Swing
While one vessel is being pressurised, the other vessel is being depressurised.

Adsorption
Separation of atmospheric air is done with the PSA principle; oxygen is separated from the air through adsorption process.

How does it work?

OXYMAT on-site PSA oxygen plants are based on the well-known PSA technology.
(PSA means pressure swing adsorption). Two pressurised vessels with zeolite ensure continuous production for separation of oxygen from other gases.

An OXYMAT O2 generator consists of two pressure vessels storing zeolite.

Dry compressed air is blown through a valve to the first vessel where the pressure is built to reach 4 to 8 bar(g). The unwanted gas (N2) is adsorbed by the zeolite during the building of pressure, and the oxygen will pass through to the accumulation tank.

While pressure is building in one vessel, the other vessel is regenerating through a decrease in pressure. This process guarantees a continuous flow. Before the subsequent adsorption or desorption stage, the pressure between the adsorption vessels will be equalised. When pressure decreases in the first vessel, and the zeolite becomes saturated, the waste product is exhausted through the exhaust system. Now the pressure in the second vessel will build up until the pressure between both vessels is once again equalised.

Advantages of PSA

The process of the PSA technology (pressure swing adsorption) is an extremely clean operation.
Air is the only ‘raw material’.

With an OXYMAT on-site PSA oxygen plant you are guaranteed an uninterrupted supply of oxygen.

This means you can produce oxygen at a place and time of your choice, and in the quantity and quality you prefer. No more waiting for external suppliers or paying excess prices for your O2.

PSA is a cost-efficient process for producing O2.
It offers the best industrial oxygen price for your application.

The PSA process is continuously repeated to provide you with an uninterrupted supply of oxygen.

Our PSA oxygen generators can produce purities between 92-95% oxygen.
