    摘要: The invention relates to a combined system for generating electrical energy consisting of a power plant and an air handling system. The power plant comprises a first gas expansion unit connected to a generator. The air handling system comprises an air compression unit, a heat exchange system, and a fluid tank. In a first operating mode, feed air is compressed in the air compression unit and cooled in the heat exchange system against a first and a second coolant. A storage fluid is generated and stored as cryogenic fluid in the fluid tank. In a second operating mode, cryogenic fluid is removed from the fluid tank, vaporized, or pseudo-vaporized, at superatmospheric pressure, and heated in the heat exchange system against the second and first coolants.

    摘要: The invention relates to refining and separating a krypton-xenon concentrate. The inventive method consists in dividing said krypton-xenon concentrate into krypton and xenon fractions in a pre-separation column, in addition removing semi-volatile impurities from each fraction, obtaining production krypton and xenon from said refined fractions in krypton and xenon columns and in addition extracting krypton from stripping gas of the krypton column by the rectification thereof. Reflux is formed in condensers-evaporators of the rectification columns in such a way that the formation of a solid phase is excluded. The operation of the rectification columns is initiated by supplying krypton to a contacting space. The inventive device for carrying out said method is also disclosed. Said invention makes it possible to increase the economical efficiency of the production of pure krypton and xenon by means of the maximum extraction thereof from an initial mixture.

    摘要: A method and apparatus for generating nitrogen from the separation of air in a single column nitrogen generator. Nitrogen rich vapor is condensed to form reflux through the vaporization of an oxygen-rich liquid stream produced as column bottoms. The vaporized oxygen-rich stream is in part recompressed in a recycle compressor, cooled and reintroduced back into the column to increase nitrogen production. The vaporized oxygen-rich stream is also in part expanded with the performance of work. The work of expansion is applied to the compression. A supplemental refrigerant stream produced by a nitrogen liquefaction unit allows the nitrogen to be taken as a liquid and increases the amount of work of expansion able to be applied to the compression.

At least one nitrogen-enriched or oxygen-enriched product stream (15, 16, 17; 53; 51, 56, 57; 19, 60) is withdrawn from the distillation column system for nitrogen-oxygen separation and warmed in the main heat exchanger (9). A fluid from an external source is passed at least at times into a liquid tank (70). At least at times fluid (71) is withdrawn in the liquid state from the liquid tank (70), vaporized in the main heat exchanger (9) and is obtained as gaseous additional product (72, 73).
