Air Separation focuses on identification of new concepts and technologies for production of oxygen for use in gasification systems. Many gasification-based energy plants run more efficiently if the oxidant is oxygen rather air, but they rely on conventional cryogenic air separation which is expensive both in terms of capital expenditure and cost to operate.

Considerations for selection of basic process cycle Air separation technology is used for the production of oxygen, nitrogen, and the rare gases that are present in air. Cryogenic separation is the industry's 'workhorse', but there are a limited number of alternative methods for separation which can be competitive in certain circumstances.
