Cryogenic air separation units (ASUs) are built to provide nitrogen or oxygen and often co-produce argon. Other methods such as membrane, pressure swing adsorption (PSA) and …

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 …

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 …

SIAD offers a comprehensive line of custom-engineered and standard-design air separation plants that produce high-purity medical and industrial-grade oxygen, nitrogen, and argon …

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 …

An air separation unit (ASU) is defined as a facility that produces nitrogen through cryogenic distillation, relying primarily on an air compression train for its power requirements.

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 …

In this e-book, we will concentrate on areas of concern to plants that have air separation units on site. Some may be owned by the company, while others may be installed by the supplier as a …

To produce industrial gases such as purified nitrogen or oxygen, atmospheric air is compressed, cooled, and separated in a distillation column or cold box. Once the cryogenic separation is …
