An air separation plant separates atmospheric air into its primary components, typically nitrogen and oxygen, and sometimes also argon and other rare inert gases. The most common method for air separation is fractional distillation. Cryogenic air separation units (ASUs) are built to provide nitrogen or oxygen and often co-produce argon.

Air separation is the most common process used to extract one or all of the main constituents of atmospheric air. The three main components are Nitrogen (78.1%), Oxygen (20.9%) and Argon (.9%). The remaining gases in the air are in trace amounts and normally not recovered.

2024年9月30日 · What is an Air Separation Unit? An Air Separation Unit (ASU) is an industrial facility used to separate atmospheric air into its primary components (namely nitrogen, oxygen, and, in some cases, argon and other rare gasses).

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. This was followed in 1904 by the first air separation plant capable of producing nitrogen.

2024年5月20日 · Air Separation Unit (ASU) is an industrial facility designed to separate atmospheric air into its primary components: nitrogen, oxygen, and occasionally argon and other rare gases. These units are essential for producing …

We offer a wide range of expanders for air separation plants, from small modularized units to full-scale cryogenic systems. As a leader in the industry, our proven designs have millions of successful hours of operation, with MTBF of more than 20 years.

An air separation unit (ASU) uses the conventional multi-column cryogenic distillation technique to produce O 2 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.

Air is drawn into a multi-stage compressor train, passing through inter-coolers to reduce its temperature. Once compressed, to 8 bar (115 psi) typically, the air is chilled further using a direct-contact water cooler, which also captures remaining particles.

This design guideline covers the basic elements of air separation units in sufficient detail to allow an engineer to design an air separation units with the suitable size of wall thickness, reflux ratio, actual stages, heat duties of a reboiler and a condenser, and permissible pressures.

Polaris Air Separation Units (ASU) provide a flexible, customized, and innovative technical solution to produce industrial gases such as Nitrogen, Oxygen, and Argon.
