摘要： In a single column distillation system for obtaining gaseous and liquid nitrogen with a variable proportions of liquid product by low-temperature separation from air, a first portion (12, 13) of nitrogen-rich fraction (5, 7, 8) is fed downstream of circulation compressor (9) to the liquefaction chamber of a condenser-evaporator (14) associated with the single column and condensed under a pressure higher than the operating pressure of the single column (4). A liquid oxygen-enriched fraction (228, 231) from the distillation column system is at least partially evaporated in the evaporation chamber of condenser-evaporator (14). A portion (18) of nitrogen-rich liquid (15, 16) from condenser-evaporator (14) is drawn off at least at times as liquid product. A second oxygen-enriched gas (221, 521) is removed from one of columns (546) of the distillation system and/or from the evaporation chamber of condenser-evaporator (14), machine expanded(23), and heated in main heat exchanger (2).

摘要： For obtaining gaseous nitrogen by low-temperature separation from air, a distillation column system has a single column (4). Compressed air (1) is cooled in a main heat exchanger (2) and fed (3) to single column (4). A nitrogen-rich fraction (5, 7, 8) is drawn off from the distillation column system and compressed at least in part in a circulation compressor (9, 1063). A first part (12, 13) of nitrogen-rich fraction (5, 7, 8) is fed downstream from circulation compressor (9) to the liquefaction chamber of a condenser-evaporator (14) and is condensed under a pressure higher than the operating pressure of single column (4), so to form nitrogen-rich liquid (15, 16). A liquid oxygen-enriched fraction (231) from the distillation column system is at least partially evaporated in the evaporation chamber of condenser-evaporator (14). A first oxygen-enriched gas (234, 533) formed in the evaporation chamber of condenser-evaporator (14), is introduced into single column (4). A second portion (19, 20, 1064) of the nitrogen-rich fraction (5, 7, 8) is drawn off at least at times as gaseous nitrogen product. A second oxygen-enriched gas (221, 521) is removed from the evaporation chamber of condenser-evaporator (14), work expanded (23), and heated in main heat exchanger (2).

摘要： The process and device are used to obtain a compressed product by low temperature separation of air in a rectification system which has a pressure column and a low pressure column. A first flow of compressed and purified feedstock air is cooled in a main heat exchanger system and is fed into the pressure column. At least one fraction from the pressure column is expanded and fed into the low pressure column. An oxygen-rich fraction from the low pressure column is liquid-pressurized and delivered to a mixing column. A heat exchange medium is fed into the lower area of the mixing column and is brought into countercurrent contact with the oxygen-rich fraction. A gaseous top product is removed from the upper area of the mixing column. A product fraction is removed from the rectification system, liquid-pressurized, vaporized in indirect heat exchange with the gaseous top product of the mixing column and is withdrawn as the compressed product. Indirect heat exchange is carried out for vaporization of the liquid-pressurized product fraction in the main heat exchanger system.

摘要： Oxygen and nitrogen are produced by low-temperature separation of air in a rectification system that has a pressure column (4) and a low-pressure column (5). Charging air (1, 3) is introduced into pressure column (4). An oxygen-containing liquid fraction (8, 10) is removed from pressure column (4) and fed into low-pressure column (5). Gaseous nitrogen (17) from low-pressure column (5) is at least partially condensed in a top condenser (7) by indirect heat exchange with an evaporating cooling fluid (15). A nitrogen product stream (19) is removed from low-pressure column (5) and/or pressure column (4). An oxygen product stream (61, 62, 63) is pulled off from low-pressure column (5). The cooling fluid for top condenser (7) of low-pressure column (5) is formed by an intermediate liquid (15) that is drawn off from an intermediate point on low-pressure column (5).

摘要： The process and the apparatus serve for producing pressurized oxygen and krypton/xenon by low-temperature fractionation of air. The rectifying system has a low-pressure column (3) for the nitrogen-oxygen separation and a krypton-xenon enrichment column (15). Compressed and prepurified feed air (4) is introduced into the rectifying system. A first oxygen fraction (11) is taken off from the low-pressure column (3), brought (12) to an elevated pressure in the liquid state, vaporized and removed as gaseous pressurized oxygen product (24). In addition, a second oxygen fraction (16) is taken off from the low-pressure column (3) and passed (18) into the lower or central region of the krypton-xenon enrichment column (15). The first oxygen fraction (11) is taken off at least one actual or theoretical plate above the bottom of the low-pressure column (3) and, after the pressure elevation (12) is introduced (14) in the liquid state into the upper region of the krypton-xenon enrichment column (15). A krypton-enriched and/or xenon-enriched fraction (19) is taken off from the lower region of the krypton-xenon enrichment column (15). The pressurized oxygen product (24) is withdrawn in the gaseous state from the upper region of the krypton-xenon enrichment column (15).

摘要： In order to boost production of a product (A) of an existing separation plant (X, 1), an additional plant (Y) is integrated with the original plant so as to enable the original plant (X) to produce more of that product (A+B), whilst the additional plant may or may not necessarily itself produce the same product directly. For example, air is separated in a first unit, which is an existing double column distillation plant, to produce an oxygen rich fluid. So as to increase the production of the oxygen rich fluid, a second unit, which is a wash column (15), is integrated with the first unit. Air (41) is separated in the single nitrogen wash column (15) to remove oxygen and gaseous nirogen (42) is produced at the top of the column. The wash column is fed with liquid nitrogen (39) from the high pressure column (25) of an existing air separation unit.
