Working principle: According to the principle of variable pressure adsorption, high quality carbon molecular sieves are used as adsorbent to produce nitrogen from the air under a certain pressure. The compressed air, which has been purified and dried, is adsorbed under pressure and desorbed under reduced pressure in the adsorber. Due to the aerodynamic effect, the diffusion rate of oxygen in the micro-pores of the carbon molecular sieve is much greater than that of nitrogen, and the oxygen is preferentially adsorbed by the carbon molecular sieve, while the nitrogen is enriched in the gas phase to form the finished nitrogen gas. Then by reducing the pressure to atmospheric pressure, the adsorbent desorbs the adsorbed oxygen and other impurities, is to achieve regeneration. Generally in the system set up two adsorption tower, a tower adsorption nitrogen production, the other tower desorption regeneration, through the PLC program controller to control the start and close the pneumatic valve, so that the two towers alternate cycle, in order to achieve the purpose of continuous production of nitrogen.

PSA Technology
PSA( Pressure Swing Adsorption) is an advanced gas separation
technology, based on the physical adsorption of the internal
surface in the adsorbent to gas molecules, separating the gas by
the characteristics of absorbing
to the quantity of different gas in general pressure. The CMS
(Carbon Molecular Sieve) is a sorbent picked up from the air, used
in separating Oxygen and Nitrogen molecular. The absorption
quantity of CMS is greatly
higher for Oxygen than Nitrogen under the same pressure
