What is an Air Separation Unit (ASU)
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.

How to Improve Reliability and Safety of Air Separation Units
AIR SEPARATION The purified compressed air passes through an expansion turbine and heat exchangers to reduce the temperature to -173°C (-280°F). 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

Oxygen Generation and Storage
An ASU can produce 100 to over 5,000 tons of oxygen per day at purity levels of 95% to 99.5% or higher. The process of air separation consists of the following main steps: • Filtration, to remove dust and other impurities. • Compression, where the air is compressed between 72 to 144 psig and water is condensed out in inter-stage coolers.
