摘要： with a Variable Proportion of Liquid Product 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 producing a pressurized product by low-temperature producing a pressurized product by low-temperature fractionation of air in a rectification system which has a high-pressure column (13) and a low-pressure column (14), a first feed airstream (12) is introduced into the high-pressure column (13), and an oxygen-rich fraction (38) from the low-pressure column (14) is brought (39) to pressure in the liquid state and introduced (41) into a mixing column (16). A second feed airstream (6, 15) is introduced into the lower region of the mixing column (16) and brought into countercurrent contact with the oxygen-rich fraction (41). The mixing column (16) is operated at a pressure (PM1S) which is lower than the operating pressure (pHDS) of the high-pressure column (13). A total airstream (1) which comprises the first and second feed airstreams is compressed (2) to a first pressure (p1) which is lower than the operating pressure (pHDS) of the high-pressure column (13) and is purified (3) at about this first pressure (p2) . The purified total airstream (4) is divided into the first (5) and the second (6) feed airstream. The first feed airstream (5) is further compressed (8) separately from the second feed airstream to a second pressure (P2) which is at least equal to the operating pressure (PHDS) of the high-pressure column (13).

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.

A heat transfer medium stream is introduced into the lower region of the mixing column (26) and is brought into countercurrent contact with the oxygen-rich fraction (22, 25). Gaseous top product (260) from the upper region of the mixing column (26) is introduced into an additional column (27). A liquid (38, 39, 40, 41) from the lower or middle region of the mixing column is introduced into the distillation column system. A krypton- and xenon-containing oxygen stream (44, 46, 47, 48) from the distillation column system is introduced into a krypton-xenon enriching column (36) from which a krypton- and xenon-enriched fraction (51) is obtained.

摘要： The process and the apparatus are used for the low-temperature fractionation of air in a three-column system which has a high-pressure column (5), a low-pressure column (7) and a medial column (6). Charge air (1, 2, 4) is introduced into the high-pressure column (5), where it is separated into a first oxygen-enriched liquid and a first nitrogen fraction (16). At least a part (19) of the first nitrogen fraction (16) is condensed in a first condenser/evaporator (8) to form a first liquid nitrogen fraction (20). A first oxygen-enriched fraction (22) from the high-pressure column (5) is introduced into the medial column (6), where it is separated into a second oxygen-enriched liquid and a second nitrogen fraction (24). At least a part of the second nitrogen fraction (24) is condensed in a second condenser/evaporator (25) to form a second liquid nitrogen fraction (26) and is added as reflux to one of the columns of the three-column system and/or is obtained as liquid product (64). A second oxygen-enriched fraction (29, 31) from the high-pressure column or from the medial column (6) is introduced into the low-pressure column (7), where it is separated into a third oxygen-enriched liquid and a third nitrogen fraction. Liquid reflux nitrogen (54, 60), which has not been formed in the second condenser/evaporator (25), is introduced into the medial column (6).

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).
