• Commercial Technologies for Oxygen Production | netl ...

    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.
