To achieve the low distillation temperatures, an air separation unit requires a refrigeration cycle that operates by means of the Joule–Thomson effect, and the cold equipment has to be kept within an …

We pioneered the world’s first air separation unit (ASU) to produce oxygen using a single-column rectification system, thus paving the way for the use of gases in industrial applications.

These units separate the air in liquid form, but utilize the refrigeration from the liquids before they exit the coldbox. The products come off the coldbox at fairly low pressure and ambient temperature.

Oct 31, 2025 · What is an Air Separation Unit? An Air Separation Unit is an industrial plant that separates atmospheric air into its main components: oxygen, nitrogen, and sometimes argon and …

Oct 5, 2025 · An air separation unit (ASU) is an industrial facility that separates atmospheric air into its individual components. The primary products extracted are nitrogen, which makes up roughly 78.1% …

Air separation plants are typically referred to as air separation units, or ASUs. Cryogenic air separation is capable of producing large quantities of high purity gas and/or liquid phase product, which is then …

Now liquefied, it passes into the cold box (Figure 3), which is industry jargon for the air separation unit, a large, heavily-insulated distillation column, designed to separate the gases in spite of their very close …

Aug 7, 2025 · Air separation equipment is designed to extract specific components from atmospheric air—primarily oxygen (O2), nitrogen (N2), and argon (Ar)—for industrial use. This is typically …

What is an Air Separation Unit? An air separation unit is an engineered process plant or device that separates atmospheric air into its constituent components, typically nitrogen, oxygen, and argon, …

Air Products has more than 75 years of experience designing, engineering, constructing and operating air separation units (ASU) for customers requiring large amounts of oxygen, nitrogen or argon. We …
