Atmospheric Pressure Swing Adsorption (APSA)

Atmospheric Pressure Swing Adsorption (APSA) is a process used to separate gases from a mixture, typically at normal atmospheric pressure. It works by selectively trapping certain gases on a material called an adsorbent when air is passed through a vessel. When the adsorbent becomes full, the pressure is reduced or the gas is replaced, releasing the captured gases and regenerating the adsorbent for reuse. This cycle allows for efficient separation of gases like oxygen or nitrogen without needing high-pressure equipment, making the process energy-efficient and suitable for various industrial and medical applications.
