Definitions
- the invention relates to a method and apparatus for variable recovery of a compressed gas product by cryogenic separation of air.
- the distillation column system of such a system can be designed as a two-column system (for example as a classic Linde double column system), or as a three or more column system. It may in addition to the columns for nitrogen-oxygen separation, further devices for obtaining highly pure products and / or other air components, in particular of noble gases have, for example, an argon production and / or a krypton-xenon recovery.
- condenser-evaporator refers to a heat exchanger in which a first condensing fluid stream undergoes indirect heat exchange with a second evaporating fluid stream.
- Each condenser-evaporator has a liquefaction space and an evaporation space, which consist of liquefaction passages or evaporation passages.
- the condensation (liquefaction) of the first fluid flow is performed, in the evaporation space the evaporation of the second fluid flow.
- Evaporation and liquefaction space are formed by groups of passages that are in heat exchange relationship with each other.
- the evaporation space of a condenser-evaporator can be designed as a bath evaporator, falling-film evaporator or forced-flow evaporator.
- a liquid product placed under pressure is vaporized against a heat transfer medium and finally recovered as an internally compressed compressed gas product.
- This method is also called internal compression. It serves to obtain gaseous printed product.
- the product stream is then "pseudo-evaporated".
- the product stream may be, for example, an oxygen product from the low-pressure column of a two-column system or a nitrogen product from the high-pressure column of a two-column system or from the liquefaction space of a main condenser via which the high-pressure column and low-pressure column are in heat-exchanging connection
- a high-pressure heat carrier is liquefied (or pseudo-liquefied when it is under supercritical pressure).
- the heat transfer medium is often formed by part of the air, in the present case by the "second partial flow" of the compressed feed air.

- the invention relates to systems in which the total feed air is compressed to a pressure well above the highest distillation pressure prevailing inside the columns of the distillation column system (this is normally the high pressure column pressure).
- HAP processes HAP - high air pressure
- This is the "first pressure”, ie the outlet pressure of the main air compressor (MAC main air compressor), in which the total air is compressed, for example, more than 4 bar, in particular 6 to 16 bar above the highest distillation pressure.
- the "first pressure” is between 17 and 25 bar.
- the main air compressor is regularly the only external energy driven machine for compressing air.
- a “single machine” is understood to mean a single stage or multi-stage compressor whose stages are all connected to the same drive, with all stages in housed in the same housing or connected to the same gear.
- MAC-BAC processes in which the air in the main air compressor is compressed to a relatively low total air pressure, for example the operating pressure of the high-pressure column (plus line losses). Part of the air from the main air compressor is compressed to a higher pressure in an external energy driven air booster (BAC).
- BAC external energy driven air booster
- This higher pressure air component (often called the choke flow) provides the majority of the heat required for (pseudo) evaporation of the internally compressed product in the main heat exchanger. It is depressurised downstream of the main air compressor in a throttle valve or in a liquid turbine (DLE) to the pressure required in the distillation column system.
- DLE liquid turbine
- the invention is based on the object to further improve such a method in terms of energy efficiency.
- One of the two turbine streams or both can be recompressed together with the second partial flow in the first booster to the second pressure, as described in the claims 3 and 4.
- the third partial flow can remain without recompression; it is then introduced under the first pressure in the second air turbine.
- the stream at least partially condensed in the evaporation space of the bottom evaporator of the high-pressure column is then preferably fed to the high-pressure column at an intermediate point.
- FIGS. 1 and 2 illustrated schematically embodiments.
- atmospheric air is sucked through a filter 1 from a main air compressor 2.
- the main air compressor has five stages in the example and compresses the total air flow to a "first pressure", for example 19.7 bar.
- the total air flow 3 downstream of the main air compressor 2 is cooled under the first pressure in a pre-cooling 4.
- the pre-cooled total air flow 5 is purified in a cleaning device 6, which is formed in particular by a pair of switchable molecular sieve adsorber.
- the purified total air flow 7 is recompressed to a first part 8 in a hot air compressor 9 with aftercooler 10 to a "second pressure" of for example 24 bar and then into a "first partial flow” 11 (first turbine air flow) and a "second partial flow”.
- Divided 12 first inductor current).
- the first substream 11 is cooled in a main heat exchanger 13 to a first intermediate temperature of about 135K.
- the cooled first partial flow 14 is expanded in a first air turbine 15 from the second pressure to about 5.5 bar to perform work.
- the first air turbine 15 drives the warm air compressor 9.
- the work-performing relaxed first partial flow 16 is introduced into a separator (phase separator) 17.
- the liquid portion 18 is introduced via lines 19 and 20 into the low-pressure column 22 of the distillation column system.
- the distillation column system comprises a high-pressure column 21, the low-pressure column 22 and a main condenser 23 and a conventional argon production 24 with crude argon column 25 and pure argon column 26.
- the main condenser 23 is designed as a condenser-evaporator, in the concrete example as a cascade evaporator.
- the operating pressure at the top of the high pressure column is in the example 5.3 bar, the one at the top of the low pressure column 1.35 bar.
- the second partial flow 12 of the feed air is cooled in the main heat exchanger 13 to a second intermediate temperature, which is higher than the first intermediate temperature, fed via line 27 to a cold compressor 28 and there recompressed to a "third pressure" of about 35 bar.
- the recompressed second partial stream 29 is at a third intermediate temperature, which is higher than the second intermediate temperature, again introduced into the main heat exchanger 13 and cooled there to the cold end.
- the cold second partial stream 30 is expanded in a throttle valve 31 to approximately the operating pressure of the high-pressure column and fed via line 32 to the high-pressure column 21.
- a part 33 is removed again, cooled in a supercooling countercurrent 34 and fed via the lines 35 and 20 in the low-pressure column 22.
- a "third substream" 436 of the feed air is introduced under the second pressure into the main heat exchanger 13 and cooled there to a fourth intermediate temperature, which in the example is slightly higher than the first intermediate temperature.
- the cooled third partial flow 37 is expanded in a second air turbine 38 from the first pressure to perform work.
- the working power relaxed turbine stream 339 has a pressure which is at least 1 bar, in particular 4 to 10 bar above the operating pressure of the high-pressure column, and a temperature which is at least 10 K, in particular 15 to 40 K above the inlet temperature of the low-pressure nitrogen streams 55, 61 is located at the cold end of the main heat exchanger. This stream is then further cooled in the cold part of the main heat exchanger.
- the further cooled third partial flow 340 is expanded as a third throttle flow in a throttle valve 341 to about high-pressure column pressure and introduced via line 32 into the high-pressure column.
- the heat exchange process in the main heat exchanger can be further optimized, in particular in the case of relatively low GAN-IC pressures of for example 7 to 15 bar, in particular about 12 bar.
- the second air turbine 38 drives the cold compressor 28.
- the working expanded third partial flow 339 is supplied via line 40 of the high-pressure column 21 at the bottom.
- a "fourth partial flow” 41 (second throttle flow) flows through the main heat exchanger 13 from the hot to the cold end under the first pressure.
- the cold fourth partial stream 42 is expanded in a throttle valve 43 to approximately the operating pressure of the high-pressure column and fed via line 32 to the high-pressure column 21.
- the oxygen-enriched bottom liquid 44 of the high-pressure column 21 is cooled in the subcooling countercurrent 34 and introduced via line 45 into the optional argon recovery 24. Resulting vapor 46 and remaining liquid 47 are fed into the low-pressure column 22.
- a first part 49 of the top nitrogen 48 of the high-pressure column 21 is completely or substantially completely liquefied in the liquefaction space of the main condenser 23 against liquid oxygen evaporating in the evaporation space from the bottom of the low-pressure column.
- a first part 51 of the liquid nitrogen 50 produced in the process is introduced as reflux to the high-pressure column 21.
- a second part 52 is cooled in the subcooling countercurrent 34, fed via line 53 into the low pressure column 22. At least a portion of the liquid low pressure nitrogen 53 serves as reflux in the low pressure column 21; another part 54 can be obtained as liquid nitrogen product (LIN).
- gaseous impurity nitrogen 61 is withdrawn, warmed in the supercooling countercurrent 34 and in the main heat exchanger 13.
- the warm impure nitrogen 62 may be vented (63) into the atmosphere (ATM) and / or used as the regeneration gas 64 for the purifier 6.
- Gaseous nitrogen 55 from the top of the low pressure column 22 is also heated in the subcooling countercurrent 34 and main heat exchanger 13 and withdrawn via line 56 as low pressure nitrogen product (GAN).
- the lines 67 and 68 connect the low-pressure column 21 with the crude argon column 25 of argon recovery 24th
- a first portion 70 of the liquid oxygen 69 from the bottom of the low-pressure column 21 is withdrawn as the "first product stream", brought to a "first product pressure” of, for example, 37 bar in an oxygen pump 71 and vaporized under the first product pressure in the main heat exchanger 13 and finally via line 72 as "first compressed gas product” (GOX IC - compressed gas internal oxygen) won.
- a second portion 73 of the liquid oxygen 69 from the bottom of the low-pressure column 21 is optionally cooled in the subcooling countercurrent 34 and recovered via line 74 as a liquid oxygen product (LOX).
- LOX liquid oxygen product
- a third part 75 of the liquid nitrogen 50 from the high-pressure column 21 and the main condenser 23 is also subjected to internal compression by being brought in a nitrogen pump 76 to a second product pressure of 12 bar, for example, under the second product pressure in the main heat exchanger 13 pseudo and finally recovered via line 77 as internally compressed gaseous nitrogen pressure product (GAN IC).
- GAN IC internally compressed gaseous nitrogen pressure product
- a second part 78 of the gaseous top nitrogen 48 of the high-pressure column 21 is warmed in the main heat exchanger and recovered via line 79 either as a gaseous medium pressure product or - as shown - used as a sealing gas (seal gas) for one or more of the illustrated process pumps.
- FIG. 2 differs from FIG. 1 in that the third partial flow 36 of the feed air is introduced under the first pressure into the main heat exchanger 13 and the second turbine 38 thus has a correspondingly lower inlet pressure.
- the high-pressure column has a sump evaporator 351. This is used in particular when at least temporarily a particularly low liquid production or even pure gas operation is desired.
- the turbine 38 of the previous embodiments can not be driven with their maximum throughput, because otherwise too much air would have to be driven as a third partial flow through the cold end of the main heat exchanger and the operation of the main heat exchanger would be less efficient.
- FIG. 3 can now be passed at a particularly low liquid production part 350 of the third partial flow from the turbine 38 on the main heat exchanger.
- the turbine 38 (and thus the coupled cold compressor) can now be operated at full throughput, without burdening the heat exchange process in the main heat exchanger.
- the stream 350 is at least partially condensed in the evaporation space of the bottom evaporator 351 and then via line 352 of High-pressure column fed at an intermediate point. He intensifies the distillation in the lower part of the high-pressure column.
- the stream 350 can also be cooled to the dew state before it is introduced into the bottom evaporator in the main heat exchanger. This can be done in a separate passage, but also by intermediate removal at a suitable location and appropriate Umspeisung.
