Techincal principle of PSA nitrogen plant

PSA Standard Nitrogen Generator is a machine producing nitrogen by separating nitrogen from air. It adopts the principle of PSA(pressure swing adsorption). 

Pressure swing adsorption processes rely on the fact that under pressure, gases tend to be attracted to solid surfaces, or "adsorbed". The higher the pressure, the more gas is adsorbed; when the pressure is reduced, the gas is released, or desorbed.

Nitrogen plant process flow
The main process flow of PSA skid nitrogen plant is as following:

Air Compressor suction air from atmosphere,then the compressed air enters one air treatment part to get rid of dust,water, dust,etc, achieving clean and dry compressed air. This air treatment part mainly consists of three filters, one Refrigerant Dryer and one activated carbon oil remover. After treatment, the compressed air enters one air tank to make air stable. Then the compressed air enters PSA nitrogen/oxygen separator. After passing through this nitrogen/oxygen separator part, nitrogen is collected. The produced nitrogen enters one nitrogen buffer tank. At the outlet of nitrogen buffer tank, stable and qualified nitrogen is sent to using point.
