What does an air separation unit operator do?

An Air Separation Unit (ASU) Operator is responsible for operating and maintaining equipment that separates atmospheric air into its primary components—mainly oxygen, nitrogen, and argon—using processes such as cryogenic distillation. They monitor control panels, adjust valves, and ensure the plant runs safely and efficiently. Operators also perform routine checks, troubleshoot issues, and maintain equipment to minimize downtime and ensure product quality. This role is vital in industries like steel manufacturing, chemical processing, and healthcare, where purified gases are essential.
