Under the balance of adsorption, when any kind of adsorbent adsorbs the same gas, the higher the gas pressure, the greater the adsorption capacity is. Otherwise, the lower the pressure, the smaller the adsorption power is.

As the chart shows, carbon molecular sieve shows difference in adsorbing oxygen and nitrogen. Carbon molecular sieve is a substance with a lot of micropores inside. The PSA principal is to achieve the separation goal of oxygen and nitrogen which based on the adsorption quantity difference in the carbon molecular sieve when the pressure is certain.

When the pressure rises, the carbon molecular sieve adsorbs the oxygen and produces the nitrogen gas. When the pressure decreases, the carbon molecular sieve starts to desorb the oxygen until the pressure equals to the ordinary pressure. At that time, the carbon molecular sieve desorbs the oxygen completely. The PSA nitrogen generator is usually equipped with adsorption towers. It controls the pneumatic valve by PLC, thus the two adsorption towers can produce the nitrogen gas alternatively. One tower adsorbs the oxygen and produces nitrogen gas, the other desorbs to regeneration to produces the required nitrogen.

Applications:
