Gasification processes require an oxidant, most commonly oxygen; less frequently air or just steam may suffice as the gasification agent depending on the process. Oxygenblown systems have the advantage of minimizing the size of the gasification reactor and its auxiliary process systems. However, the oxygen for the process must be separated from the atmosphere.

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.
