Abstract
An integrated air separation process produces an O,-enriched gas stream and an N,-enriched gas stream in an air separation unit. The N,-enriched gas stream is heated in a first heat exchanger associated with a first boiler and then power is generated from the heated gas stream. The O,-enriched gas stream is introduced with fuel to a combustor associated with the first boiler, producing flue gas. At least a portion of the flue gas exiting the first boiler is used to generate power. In a preferred embodiment, another portion of the flue gas exiting the first boiler is recycled to the first boiler, as a temperature controlling fluid.
