Cryogenic air separation is the most common and standard technology used for the separation of air into its constituents. It results in a high purity product and is the most developed method currently (Hashim, 2011). This is a highly energy-intensive process due to the low temperatures that need to be achieved, as can be seen from Table 1 above.

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. In very large air separation units (ASU) Neon, Xenon and Krypton are recovered in small amounts.
