Pressure swing adsorption (PSA) is a new type of gas separation technology.

Taking adsorbent molecular sieve as an example, the principle is to use molecular sieve to "adsorb" different gas molecules to separate gas mixtures. It uses air as raw material, adopts high-efficiency, high-selectivity solid adsorbent to selectively adsorb nitrogen and oxygen, and realizes the separation of nitrogen and oxygen in the air.

After a period of time, the adsorption of oxygen by the molecular sieve reaches equilibrium. According to the different characteristics of carbon molecular sieve adsorbing gas at different pressures, the pressure is reduced to release carbon molecular sieve to adsorb oxygen. This process is called regeneration. The pressure swing adsorption method initially uses two towers in parallel, alternately performing pressure adsorption and decompression regeneration to obtain a continuous oxygen flow;
