    • The invention relates to a method for producing air products by means of low-temperature separation of air in a distillation column system (7) of an air separation plant. Said system comprises a high-pressure column (71) and a low-pressure column (72), wherein the overall total amount of air used in the method is compressed in a main compressor (2) to a main compressor pressure, which is at least 4 bars higher than an operating pressure at which the high-pressure column (71) is operated. A first portion of the total air amount compressed to the main compressor pressure is conveyed to the hot side of a main heat exchanger (6), and is cooled therein, is expanded in an expansion machine (12) and fed into the high-pressure column (71). A second portion of the total air amount compressed to the main compressor pressure is cooled in the main heat exchanger (6), is expanded, and is fed into the distillation column system (7). According to the invention the method is carried out in a first and in a second operating mode, subject to a liquid product quantity of at least one air product to be extracted from the air separation plant in a liquid state, wherein a generator turbine (30) is used, in which in the second operating mode a third portion of the total amount of air is expanded and blown into the atmosphere at a quantity that is higher than the quantity in the first operating mode. In the second operating mode, at least one liquid air product of the air separation plant is extracted at a greater liquid product quantity than in the first operating mode. The first portion of the total amount of air is conveyed to the expansion machine (12) at most at a pressure, at which said first portion is conveyed to the hot side of the main heat exchanger (6). The invention further relates to an air separation plant configured for carrying out such a method.

    • A dry condenser which permits heat exchange even in a small temperature difference is used in each condenser for a crude argon column, a deoxidation column, and a high-purity argon column in an argon separator utilizing air liquefaction and rectification. An oxygen-enriched liquefied air withdrawn from the plate located above the bottom of a lower column in a multi-rectifying column is used as a coolant for each condenser. Thus it is possible to widen the temperature difference between the condensation side and the evaporation side in the condensers for respective columns, to dispense with a blower for pressurizing crude argon even when the total number of theoretical plates of the crude argon column and the deoxidation column exceeds 100 and, consequently, to reduce apparatus and operation costs. Further, it is possible to render the condenser in each column small and compact, thus shortening the time taken for starting. Furthermore, the adoption of the liquefied air withdrawn from plates located above the bottom can eliminate a fear of hydrocarbon precipitation.
    • 使用空气液化和整流的氩分离器中的粗氩塔,脱氧塔和高纯度氩塔的每个冷凝器中使用即使在较小的温度差也允许热交换的干式冷凝器。 从位于多精馏塔的下塔底部的板中取出的富氧液化空气用作每个冷凝器的冷却剂。 因此,可以扩大各列的冷凝器中的冷凝侧和蒸发侧之间的温度差,即使在粗氩塔和脱氧塔的理论塔板总数 超过100,从而降低设备和操作成本。 此外,可以使各列中的冷凝器小而紧凑,因此缩短了起动所需的时间。 此外,从位于底部的板上取出的液化气的采用可以消除对碳氢化合物沉淀的恐惧。
