    摘要: Feed air is fed to a rectifying system (14, 15) for low-temperature separation, from which a liquid fraction (31, 32) is taken off and introduced into a first reservoir tank (33). The pressure of a variable rate of the liquid fraction (34) is increased (35). The liquid fraction (36) is evaporated under the elevated pressure by indirect heat exchange (12) and obtained as a gaseous pressurized product (37). A heat-transport medium circulates in a refrigeration cycle which has a cycle compressor (41, 42). A first partial stream (45) of the heat-transport medium (44) compressed in the cycle compressor (41, 42) is fed to the indirect heat exchange (12) to evaporate the liquid fraction (36) and is liquefied, at least in part, in the course of this. A second partial stream (59) of the heat-transport medium (44) compressed in the cycle compressor (41, 42) is expanded (43) so as to perform work. Liquefied heat-transport medium (45, 48) is buffered in a second reservoir tank (49).

    摘要: A process and apparatus for recovery of pure argon from air utilize a rectification system comprising at least one air separating column (9) and a pure argon column (25). An argon-enriched mixture (24) of air gases is introduced into the pure argon column (25) in the lower region of which an essentially nitrogen-free argon product (26) is recovered. The head fraction (28) of the pure argon column (25), is liquefied at least partly by indirect heat exchange (29) using the evaporating cooling medium (11, 30). The condensate (28a) formed thereby is returned into the pure argon column. The indirect heat exchange (29) is carried out by means of a cooling medium (11, 30) which has an oxygen content of at least 10%. Independently thereof, the lower region of the pure argon column (25) is heated by indirect heat exchange (27) by means of a heating medium (11) in a liquid state, for example, with sump liquid from a pressure column (8).

    摘要: For extracting argon, air is separated in a rectifying system comprising at least one air separating column and one crude argon column. An argon-containing oxygen fraction is taken from the air separating column and is introduced into a crude argon column. In the upper area of the crude argon column, a crude argon fraction is removed and a first reflux liquid is charged. A first residual fraction is taken from the lower area of the crude argon column. The crude argon fraction is introduced into the lower area of a semipure column. In the upper area of the semipure column, an argon fraction is taken which has reduced oxygen, and a second reflux liquid is charged. From the lower area of the semipure column, a second residual fraction is taken which forms the first reflux liquid for the crude argon column.

    摘要: The process serves for generating a pressurized product by low-temperature air fractionation. Feed air (1) is compressed (2), purified (4), cooled (9) and fed to a distillation column system (12) for nitrogen-oxygen separation (11, 23). A liquid product stream (13) is taken off from the distillation column system (12) for nitrogen-oxygen separation, brought (14) in the liquid state to an elevated pressure (PIV) and at this elevated pressure (PIV) vaporized or pseudovaporized (9). The (pseudo)vaporized product stream (16) is fed (17) as pressurized product to a gas pressure reservoir (19) which has a variable pressure (PA). The elevated pressure (PIV) is varied. The elevated pressure (PIV) is varied as a function of the pressure (PA) of the gas pressure reservoir (19).
