    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： In the method and device, nitrogen is obtained by two-stage rectification of air in a double column. Double column contains a high-pressure column and a medium-pressure column that are in a heat-exchange relationship with each other. Entering air is compressed, purified, cooled in a main heat exchanger against separation products, and fed to rectification. At least one nitrogen product fraction is taken from high-pressure column. A nitrogen gas fraction from double column is heated, expanded, and brought into indirect heat exchange with an oxygen-enriched liquid from the lower region of medium-pressure column. In this way, the nitrogen gas fraction is at least partially condensed and the oxygen-enriched liquid is at least partially evaporated. The condensate formed in the indirect heat exchange is at least partially fed to medium-pressure column. The nitrogen gas fraction is heated upstream of expansion to an intermediate temperature that is between the temperatures at the cold end and the warm end of main heat exchanger.

    摘要： The process and the device are used for low-temperature separation of air with a distilling-column system for nitrogen-oxygen separation (20), which has at least one separation column (21, 22). A main air stream (1, 5) is compressed in an air compressor (2) and purified in a purification device (4). A first air stream (7) and a second air stream (8) are diverted from the main air stream (5). The first air stream (7) is further compressed in two secondary compressors (10, 13) that are connected in series. The further compressed first air stream (15) is cooled by indirect heat exchange (16), and at least partially liquefied or pseudo-liquefied, and then introduced into the distilling-column system for nitrogen-oxygen separation (20). The second air stream (8) is cooled by indirect heat exchange (16) and then, divided into two partial streams (24, 27), is actively depressurized in two expanders (25, 28), whereby the two expanders have essentially the same inlet pressure. The actively depressurized partial streams (26, 29) of the second air stream are introduced (30, 129) at least in part into the distilling-column system for nitrogen-oxygen separation (20). The mechanical energy that is produced in the active depressurization (25, 28) of the second air stream is used at least partially in the driving of the two secondary compressors (10, 13) that are connected in series. A liquid product stream (31) is removed from the distilling-column system for nitrogen-oxygen separation (20), brought to an elevated pressure in the liquid state (32), and evaporated or pseudo-evaporated under this elevated pressure by indirect heat exchange (16) with the first air stream (15), and finally removed as a gaseous product stream (34). Both secondary compressors (10, 13) are operated with an inlet temperature that is higher than 250 K, in particular higher than 270 K.

    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 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).
