Pressure Swing Adsorption (PSA), which is based on the difference in adsorption capacity of different gases on adsorbents, and achieves gas separation, purification, or purification by changing the operating pressure, is a commonly used gas separation technology. During the pressure swing adsorption process, certain components of the gas under high pressure are adsorbed by the adsorbent, while other components are adsorbed through the adsorption bed layer; Subsequently, the pressure is reduced to allow the adsorbed components to desorb, thereby achieving gas separation.

Introduction to Subdivision Types

Classified by adsorbent type:

Physical PSA: Using the principle of physical adsorption, the adsorbent and adsorbate are adsorbed through intermolecular forces, such as activated carbon, molecular sieve, etc.

Chemical PSA: Using the principle of chemical adsorption, a chemical reaction occurs between the adsorbent and the adsorbate to form chemical bonds, such as metal oxides, activated carbon fibers, etc.

Classified by operation method:

Vacuum pressure swing adsorption (VPSA): During the adsorption process, a vacuum pump is used to reduce pressure and cause the adsorbed components to desorb.

Pressure cycling pressure swing adsorption (PCSA): Gas adsorption and desorption are achieved by periodically changing the operating pressure.

Classified by gas separation purpose:

Purified PSA: mainly used to purify a certain component from mixed gases, such as natural gas purification, hydrogen recovery, etc.

Purifying PSA: mainly used to remove impurities in mixed gases, such as air separation, gas dehydration, etc.
