Collection: Air Separation Unit (ASU)

An air separation unit (ASU) is an industrial facility designed to separate and produce high-purity gases, such as oxygen, nitrogen, and argon, from atmospheric air. It operates through a process called cryogenic distillation, which relies on the differences in boiling points of various gases. In an ASU, ambient air is compressed and cooled, leading to the liquefaction of air components. These liquefied gases are then separated and purified by distillation at extremely low temperatures.
