    摘要： In a process for delivering pressurized gas from an apparatus for separating air by cryogenic distillation, a stream of oxygen-rich liquid or gas having a nominal flow rate is withdrawn from a low-pressure column, an oxygen-rich liquid purge stream is withdrawn as bottoms from the low-pressure column and the oxygen-rich liquid purge stream is sent to a storage tank, in the event of a reduction in the production by the column system or an increase in the demand by a customer, a back-up stream is withdrawn from the storage tank and vaporized in a back-up reboiler and only if the liquid level in the storage tank exceeds a given threshold, a liquid stream is withdrawn from the storage tank constituting at most 2% of the nominal production output of the oxygen-rich stream and is sent to the back-up reboiler.

    摘要： A method and apparatus serve for the cryogenic separation of air in an air separation plant which has a main air compressor, a main heat exchanger and a distillation column system with a high-pressure column and a low-pressure column. All of the feed air is compressed in the main air compressor to a first air pressure which is at least 3 bar higher than the operating pressure of the high-pressure column. A first part of the compressed total air flow, as first air flow at the first air pressure, is cooled and liquefied or pseudo-liquefied in the main heat exchanger, then expanded and introduced into the distillation column system. A second part of the compressed total air flow, as second air flow, is post-compressed in a turbine-driven post-compressor to a second air pressure.

    摘要： The method and the apparatus described are used for generating electrical energy in a combined system comprising a power plant and a low-temperature air separation unit. A feed air stream is compressed in a main air compressor, cooled, and introduced into a distillation column system having a high-pressure column and a low-pressure column. A first oxygen-enriched stream from the distillation column system is introduced into the power plant. In a first operating mode, cryogenic liquid from the distillation column system is introduced into a liquid tank and is stored there at least in part. In a second operating mode, stored cryogenic liquid is removed from the liquid tank and introduced into the distillation column system. A second process fluid from the distillation column system is heated and then actively depressurized in a hot expansion turbine. In addition, in the second operating mode, a nitrogen-enriched product stream from the high-pressure column is also heated to a high temperature and then depressurized in the hot expansion turbine.

    摘要： The invention relates to a process for the low-temperature fractionation of air in a rectification unit, which comprises a pressure column (1) a low-pressure column (2) and a condenser-evaporator system having at least two falling-film evaporators (203, 204). Oxygen-rich liquid from the low-pressure column (2) is introduced into the evaporation passages of the first and second falling-film evaporators (203, 204) and is partially evaporated. Unevaporated oxygen-rich liquid from the first falling-film evaporator (203) is transferred into the evaporation passages of the second falling-film evaporator (204).
