Working Principle of PSA Nitrogen Generator

Under a certain pressure, using the large difference of the diffusion rate between nitrogen and oxygen from the air.
In the carbon molecular sieve, a large number of oxygen is adsorpted by carbon molecular sieve, while nitrogen is collected in a short time, to achieve separation of oxygen and nitrogen.
The adsorption capacity of carbon molecular sieve is significantly different with different oxygen pressures, reducing the pressure will release oxygen from carbon molecular sieve, this make carbon molecular sieve regeneration, then can be used repeatedly.
Using two adsorption towers, one for adsorption and nitrogen generator, the other for desorption and recycling. They switch with each other, thus continuous output of high-quality nitrogen.

Reliable operation

Advanced process design, scientific distribution structure of gas, adsorption tower with patent composite bed structure, unique filling process and special protection measures of carbon molecular sieve, and the cylinder automatic pressure compensation device, ensure that the nitrogen generator equipment can be used over ten years.

Continuous stable production

Adopt international brand valves, the life is 300 million times, efficient and reliable, to ensure continuous and reliable operation of the device.

Advanced control system

PLC control system, high degree of automation, unmanned operation.
Optional touch screen control system, industrial computer control system. Adopt humanized Chinese / English interface design, with multi-screen display function, online display and monitor nitrogen purity, flow rate, pressure, temperature, dew point, fault signal and other parameters, operating parameters can be modified online, remote monitoring, remote transmission and remote start-stop function, high degree of automation, easy to operate, can realize the automatic unmanned operation, and can be joint control with user's DCS system.

The stable quality of Nitrogen
The adsorption process of nitrogen production, purity and pressure adjustable; Emptying automatic interlock devices to ensure nitrogen production, purity, and pressure long-term stability.

Low operating costs

In the small and medium scale equipment, the operating cost of PSA nitrogen generator is lower, compared with other nitrogen generator methods(including cryogenic nitrogen, membrane nitrogen, liquid nitrogen, nitrogen cylinders).
