What Is the Process of Air Separation Unit?
An air separation unit (ASU) uses the conventional multi-column cryogenic distillation technique to produce O2 from compressed air at high purity and recovery rate. ASU's energy consumption is related to recovery since it is linked to the air flow required by thermal power. An Air Separation Unit (ASU) is an industrial process that separates atmospheric air into its primary components—namely nitrogen, oxygen, and sometimes argon and other rare inert gases. The process is essential for producing high-purity gases used in various industries, including healthcare, manufacturing, and chemical production. Here's a breakdown of how an ASU works: 1. Atmospheric Air Intake The air separation unit process begins by drawing in atmospheric air. This air contains approximately 78% nitrogen, 21% oxygen, and 1% argon, along with trace amounts of other gases. The air is typically filtered to remove dust, moisture, and other impurities. 2.
