Modularisation Technology PSA Nitrogen Generator, Nitrogen Generation System
Process Description
A booster is used to elevate the pressure of air. Then, a refrigerating dryer is introduced to remove the moisture. Finally, carbon molecular sieves beds are employed to separate the nitrogen from the oxygen, where a desirable nitrogen product will be guaranteed.
The adsorbent is carbon molecular sieves. It is just making use of the property that the adsorption rate of oxygen and nitrogen differs on the surface of the carbon adsorbent to adsorb O2 and desorb N2. The on/off valves are controlled by the programmable logic controller (PLC) to complete each cycle of adsorption and desorption and then nitrogen is produced with the required purity. The two adsorbers are in adsorbing and desorbing alternatively to ensure nitrogen to be generated constantly and steadily.
