1.Basic Introduction of PSA and VPSA

1.1 The device adopts two-tower pressure swing adsorption and oxygen production, and ses molecular sieve to adsorb nitrogen from the air to separate and extract rich oxygen. The theoretical purity of extracted oxygen is 95%. Pressure Swing Adsorption (PSA) is a kind of Advanced gas separation technology.
1.2 The basic principle of pressure swing adsorption is to rely on the solid adsorbent to separate the gas of different components. Because the solid adsorbent is porous, when the gas comes into contact with it, a phenomenon of containing gas will occur on the surface or inside of it, called solid adsorption of the gas; the atoms or molecules that have been adsorbed by the solid return to the gas, This is called desorption or desorption. Adsorption agent changes with the pressure, the amount of adsorption changes, the method of adsorption or desorption of gas is called pressure swing adsorption method.
