pressure swing adsorption (PSA)

Pressure Swing Adsorption (PSA) is a process used to separate specific gases from a mixture, often for producing clean oxygen or nitrogen. It works by using materials called adsorbents that trap certain gases under high pressure. When the pressure is reduced, the adsorbed gases are released, allowing the system to cycle continuously. Essentially, PSA relies on pressure changes to selectively remove unwanted gases, resulting in a purified output. This technology is efficient, energy-conscious, and widely used in medical, industrial, and environmental applications to produce high-purity gases.
