    摘要： For adjusting the capacity of a low-temperature rectification unit having a high pressure column and a low pressure column in which a fluid is introduced into the high pressure column (1) and in which liquid from the bottom of the high pressure column is directed into the low pressure column (2), the amount of liquid that is removed from the bottom of high pressure and fed to the low pressure column (2) is controlled via flow adjustment (4), wherein a nominal value for flow adjustment (4) is set to a desired amount of flow, and the liquid level of the liquid at the bottom of column (1) that operates at higher pressure is fixed without a set nominal value corresponding to the amount of liquid that is removed.

    摘要： A plate heat exchanger for indirect heat exchange of several fluid flows (30, 40, 50) with a heat transfer medium/cooling medium (10, 20) in a heat exchanger core (9) has a plurality of heat exchange passages within the core for the heat transfer medium/cooling medium (10, 20), a first fluid flow (30, 40, 50) and a second fluid flow (30, 40, 50). All heat exchange passages for the first fluid flow (40) are located In a first component area, and all heat exchange passages for the second fluid flow (30) are located in a second component area. The first and the second component areas do not intersect and each extend over the entire height of the heat exchanger core (9). The heat exchanger is particularly suitable for use in air-separation processes.

    摘要： In a process and apparatus for air separation by rectification air 1 is preliminarily separated in a first rectification stage 2 of a two-stage rectification column to obtain a nitrogen-rich fraction 4 and an oxygen-rich fraction 8. These two fractions are fed to the second rectification stage 6 and separated into oxygen and nitrogen fractions. An argon-enriched fraction, containing essentially oxygen and argon, is removed from the second rectification stage at an intermediate point and is separated in a raw argon column 10 by rectification into an argon-rich fraction 18 and a liquid fraction 19 containing essentially oxygen. The liquid fraction 19 is fed back into the second rectification stage. Another fraction 22 is removed from the raw argon column above the bottom thereof and is separated in a high-purity oxygen column 23 to produce a high-purity oxygen fraction 25, 26 and a lighter residual fraction 24. An additional nitrogen-rich fraction is removed from the head of the first rectification stage and separated in a high-purity nitrogen column 31 producing a bottom liquid fraction 29, which is fed back to the head of the first rectification stage, and a residual gas fraction 33. A high-purity nitrogen fraction 34 is removed at a point several plates below the head of the first rectification stage.

    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).
