摘要： An air product is produced in an air separation plant having a heat exchanger, an expansion/compression unit, a rectification unit, liquid storage, cold storage and an air compressor. The air supplied to the rectification unit is conducted through the main air compressor at a pressure level at least 3 bar above the highest operation pressure for the rectification unit. Cryogenic liquids are produced in a first production amount by a first operating mode, a lower second production amount by a second operating mode and a higher third production amount by a third operating mode. Cryogenic liquid is stored in the liquid storage in the third operating mode and removed from storage in the second operating mode. Cryogenic liquid is evaporated in different amounts in each operating mode, which amounts differ by no more than 10%.

摘要： The process and device serve for the low-temperature separation of air in a distillation-column system includes at least one separation column. A main air stream is compressed in an air compressor at a first pressure and is then purified. A first air stream, which is formed from at least one part of the purified main air stream, is further compressed at a second pressure that is higher than the first pressure. From the further compressed first air stream, a throttling stream and a turbine stream are branched off. The throttling stream is cooled down and liquefied or pseudo-liquefied in a main heat exchanger and is then passed on to expansion equipment. The expanded throttling stream is conducted into the distillation-column system. The turbine stream is cooled down in the main heat exchanger and under an intermediate temperature of the main heat exchanger is conducted into an expansion machine.

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： The method and device serve for generating an oxygen product by low-temperature separation of air having a distillation column system for nitrogen-oxygen separation that comprises a high-pressure column (6) and a low-pressure column (7) which contain mass-transfer sections. Liquid that drains off from the lowest mass-transfer section (32) of the low-pressure column (7) is introduced into a main condenser (8) constructed as a bath evaporator and condenser-evaporator. Between the bottom end of the lowest mass-transfer section (32) of the low-pressure column (7) and the main condenser (8) there is arranged a liquid buffer (33). In the event of a reduction in load, liquid is introduced into the liquid buffer (33) and is stored there. In the event of an increase in load, liquid stored in the liquid buffer (33) is introduced (34) into the main condenser (8).

摘要： A method for producing electrical energy in a combined energy generation plant which comprises an air treatment unit and a power station unit is proposed. In a first operating mode, air is liquefied to form an air liquefaction product (LAIR) and, in a second operating mode, an air liquefaction product is converted into a gaseous or supercritical state, in which said product is introduced into the power station unit and is used for producing electrical energy. In a third operating mode, air is condensed in the air treatment unit and used in the power station unit directly for producing electrical energy. It is envisaged that, in the first operating mode, the air is cooled to severa temperature levels by two liquid coolants and the air liquefaction product is correspondingy heated. In addition, in the first operating mode, the air is condensed stepwise over several pressure levels.

摘要： The invention relates to a method and device for obtaining compressed oxygen and compressed nitrogen by the low-temperature separation of air in a distillation column system for nitrogen-oxygen separation, said distillation column system having at least one high-pressure column (8) and one low-pressure column (460), wherein the low-pressure column (460) is in a heat-exchanging connection with the high-pressure column (8) by means of a main condenser (461) designed as a condenser-evaporator. Feed air is compressed in an air compressor (2). The compressed feed air (6, 734, 802, 840) is cooled down in a main heat exchanger (20) and at least partially introduced into the high-pressure column (8). An oxygen-enriched liquid (462, 465) is removed from the high-pressure column (8) and fed to the low-pressure column (460) at a first intermediate position (464, 467, 906). A nitrogen-enriched liquid (468, 470) is removed from the high-pressure column (8) and/or the main condenser (461) and fed to the head of the low-pressure column (460). A liquid oxygen flow (11, 12) is removed from the distillation column system for nitrogen-oxygen separation, brought to an elevated pressure in the liquid state (13), introduced into the main heat exchanger (20) at said elevated pressure, evaporated or pseudo-evaporated and heated to approximately ambient temperature in the main heat exchanger (20), and finally obtained as a gaseous compressed oxygen product (14). A high-pressure process flow (34, 734) is brought into indirect heat exchange with the oxygen flow in the main heat exchanger (20) and then depressurized (36, 38; 736, 738), wherein the depressurized high-pressure flow (37, 737) is introduced at least partially in the liquid state into the distillation column system for nitrogen-oxygen separation. A gaseous circuit nitrogen flow (18, 19) is drawn from the high-pressure column and at least partially (21) compressed in a circuit compressor (22). A first sub-flow (45, 46; 244, 242, 230; 845, 846) of the circuit nitrogen flow is removed from the circuit compressor (22, 322), cooled down in the main heat exchanger (20), at least partially condensed in the bottom evaporator (9, 209) of the high-pressure column (8) in indirect heat exchange with the bottom liquid of the high-pressure column (8), and conducted back into the distillation column system for nitrogen-oxygen separation. A second sub-flow of the circuit nitrogen flow is branched off upstream and/or downstream of the circuit compressor and/or from an intermediate stage of the circuit compressor at a product pressure (P, P1, P2, P3, P4) and obtained as a compressed nitrogen product (27, 29, 53, 564, 565). The circuit compressor (22, 322) is designed as a hot compressor and is driven by means of external energy.
