Air separation - Wikipedia

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.

PowerPoint Presentation

Cryogenic air separation takes advantage of the differing boiling points of its components as shown in Table 1. In order to start the separation process, a large quantity of the incoming air needs to be liquefied. This is accomplished by cooling the air by decreasing its temperature and manipulating the pressure until condensation begins.
