Introduction to Air Separation Unit
An air separation unit (ASU) is a crucial industrial facility that separates atmospheric air into its primary components, such as nitrogen, oxygen, and argon. This process is typically achieved through cryogenic distillation, which takes advantage of the different boiling points of these gases. Air separation units are widely used in various industries, including steelmaking, chemical production, healthcare, and electronics manufacturing. They play a vital role in providing high – purity gases for industrial processes, medical applications, and other specialized uses. Air Separation Unit
