THERMAL INTEGRATION OF OXYGEN PLANTS |
摘要 |
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 within said cryogenic air separation plant. This process also includes burning a fuel stream thereby generating a steam stream from a boiler feed water stream, wherein said stream is used for work expansion within said oxy-combustion power plant. This process also includes heating said pressurized nitrogen stream and said pressurized oxygen stream with a compressed air stream that is extracted from the air compressor of said cryogenic air separation plant, thereby forming a heated pressurized nitrogen stream and a heated pressurized oxygen stream. This process also includes burning a fuel stream with said heated pressurized oxygen stream to produce a flue gas stream. This process also includes heating said heated pressurized nitrogen stream to form a hot pressurized nitrogen stream. This process also includes work expanding said hot pressurized nitrogen stream to a lower pressure thereby forming a hot exhaust nitrogen stream and recovering energy. And this process also includes heating said boiler feed water stream by indirect heat exchange with said hot exhaust nitrogen stream.
