ABSTRACT:
A process for the integration of a cryogenic air separation plant and an oxy-combustion power plant is presented. This process includes producing a pressurized nitrogen stream and a pressurized oxygen stream, burning a fuel stream thereby generating a steam stream from a boiler feed water stream, wherein the stream is used for work expansion within the oxy-combustion power plant. This process also includes heating the pressurized nitrogen stream and the pressurized oxygen stream with a compressed air stream, thereby forming a heated pressurized nitrogen stream and a heated pressurized oxygen stream. This process also includes heating the heated pressurized nitrogen stream to form a hot pressurized nitrogen stream, work expanding the hot pressurized nitrogen stream to a lower pressure thereby forming a hot exhaust nitrogen stream and recovering energy, and heating the boiler feed water stream by indirect heat exchange with the hot exhaust nitrogen stream.
