coal processing oxygen use

How is Steel Produced? | World Coal Association

Coking coal must also have low sulphur and phosphorous contents. Almost all metallurgical coal is used in coke ovens. The coking process consists of heating coking coal to around 1000-1100ºC in the absence of oxygen to drive off the volatile compounds (pyrolysis). This process results in …

Air Separation Technology | netl.doe.gov

Air Separation Technology 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.
