摘要： The process and apparatus are based on a triple-column system, having at least a high-pressure column (7), a medium-pressure column (8) and a low-pressure column (9). Feed air (1) is compressed to a first pressure (2). A first partial stream (101, 103, 104) of the resultant air feed (3) is sent into high-pressure column (7) after it has been compressed to a second pressure (5, 102), which is at least equal to the operating pressure of the high-pressure column (7). A second partial stream (201, 202) of the compressed air feed (3) is fed into the medium-pressure column (8). A third partial stream (301, 303, 304) of the compressed air feed (3) is engine-expanded (305) and then fed (306) into the low-pressure column (9). Fractions (18; 26) from the high-pressure column (7) and the medium-pressure column (8) are introduced at least partially into low-pressure column (19, 20; 28, 29). Nitrogen-enriched top fractions (10; 21) from high-pressure column (7) and medium-pressure column (8) are condensed (11; 22). Resultant condensate (13; 24) is fed (15, 16; 25) into low-pressure column (9) as reflux. The first pressure is thus lower than the operating pressure of medium-pressure column (8), thus the second partial stream of the air feed is compressed from the first pressure to a third pressure (5), which is at least equal to the operating pressure of the medium-pressure column (8), but lower than the second pressure.
摘要翻译：该方法和装置基于具有至少高压塔（7），中压塔（8）和低压塔（9）的三塔系统。进料空气（1）被压缩至第一压力（2）。所得空气进料（3）的第一部分流（101,103,104）在其被压缩到第二压力（5,102）之后被送入高压塔（7），该第二压力至少等于高压塔（7）的工作压力。压缩空气进料（3）的第二部分流（201,202）被送入中压塔（8）。压缩空气进料（3）的第三部分流（301,303,304）被发动机膨胀（305），然后进料（306）进入低压塔（9）。将来自高压塔（7）和中压塔（8）的级分（18; 26）至少部分地引入低压塔（19,20,28,29）中。来自高压塔（7）和中压塔（8）的富氮顶馏分（10; 21）被冷凝（11; 22）。将所得的冷凝物（13; 24）作为回流进料（15,16; 25）进入低压塔（9）。因此，第一压力低于中压塔（8）的操作压力，因此空气进料的第二部分流从第一压力压缩到第三压力（5），其至少等于操作中压塔（8）的压力，但低于第二压力。

摘要： During restarting an argon column (2), two valves (15, 17) provided at the output of a pump (3) are controlled while maintaining a constant level in the base of the argon column, at the outset at a predetermined first control level (N2), then while progressively lowering the controlled value of the constant level. Use in installations for air distillation whose argon column, of the packed type, has a sufficient height to purify the argon of oxygen to an oxygen content less than 100 ppm.
摘要翻译：在重新启动氩塔（2）期间，设置在泵（3）的输出处的两个阀（15,17）被控制，同时保持在氩塔底部的恒定水平，首先在预定的第一控制水平（N2），然后逐渐降低恒定水平的受控值。在用于空气蒸馏的装置中，其填充型氩塔具有足够的高度以将氧的氩气纯化至低于100ppm的氧含量。

摘要： An apparatus for producing high purity oxygen and nitrogen in the liquid and gaseous phases. The apparatus is a modular, mobile system employing a low design operating pressure. The system purifies ambient air through filters and a dual immobilized fixed bed molecular sieve type pressure swing adsorber prior to the cryogenic distillation of the air. Through the incorporation of the pressure swing adsorber having a high frequency regeneration cycle, the disclosed system provides a reduced system size. The configured system employs waste gas from the distillation process to purge the pressure swing adsorber. The cryogenic distillation procedure includes a heat exchanger, a turboexpander, high and low pressure distillation columns, a subcooler and a condenser.
