    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.

    摘要： A method of liquid air energy storage is provided. This method includes liquefying and storing air to form a stored liquid air during a first period of time; during a second period of time, introducing a compressed air stream into a cryogenic system, wherein the cryogenic system comprises at least one cold compressor, and at least one heat exchanger. The method includes producing a first exhaust stream and a second exhaust stream. The method also includes vaporizing at least part of the stored liquid air stream in the heat exchanger, thereby producing a first high pressure compressed air stream, then combining the first high pressure compressed air stream, the first exhaust stream and the second exhaust stream to form a combined exhaust stream, heating the combined exhaust stream, then expanding the heated combined exhaust stream in an expansion turbine to produce power.
