Definitions
- the invention relates to a method according to the preamble of patent claim 1.
- the basics of cryogenic separation of air in general and the construction of two-column systems in particular are described in the monograph " Cryogenics "by Hausen / Linde (2nd edition, 1985 ) and in one Review by Latimer in Chemical Engineering Progress (Vol. 63, No.2, 1967, page 35 ).
- the heat exchange relationship between the high-pressure column and the low-pressure column of a double column is generally realized by a main condenser, in which head gas of the high-pressure column is liquefied against vaporizing bottom liquid of the medium-pressure column.
- the distillation column system of the invention may be designed as a classical double column system, but also as a three or more column system. It may have, in addition to the columns for nitrogen-oxygen separation, other devices for obtaining other air components, in particular noble gases, for example an argon recovery.
- the main condenser is referred to as a "condenser-evaporator” is 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 a first fluid flow is performed, in the evaporation space the evaporation of a second fluid flow.
- Evaporation and liquefaction space are formed by groups of passages that are in heat exchange relationship with each other.
- the “main heat exchanger” is used to cool feed air under a first, subcritical pressure less than 1 bar above the operating pressure of the high pressure column, in indirect heat exchange with recycle streams from the distillation column system. It can be a single or multiple parallel and / or serial connected to heat exchanger sections, for example, from one or more plate heat exchanger blocks. When the heat exchanger sections are connected in parallel, an air feed stream flows below each of them below the first, subcritical pressure.
- wound heat exchanger In a "wound heat exchanger" several layers of tubes are wound onto a core tube. Through the individual tubes a medium is passed, which occurs in heat exchange with a flowing in the space between the tubes and a surrounding jacket medium. The tubes are brought together at the upper heat exchanger end in several groups and led out in the form of bundles from the outside.
- wound heat exchangers their preparation and their application are, for example, in Hausen / Linde, Tiefftemperaturtechnik, 2nd ed. 1985, p. 471-475 described.
- the invention has for its object to provide such a method and a corresponding device, which have a high efficiency at the same time relatively low expenditure on equipment and are particularly suitable for the supply of a coal gasification power plant (IGCC - Integrated Combined Cycle).
- IGCC coal gasification power plant
- the further increase in the energy efficiency of the process is the joint work-relaxing of the two parts of the second feed air flow in a liquid turbine (DLE - dense liquid expander).
- the mechanical energy generated at the liquid turbine can either be delivered directly to a compressor or converted into electrical energy via a generator.
- an equalizing flow (“third partial flow” of the second feed air stream) is taken from the high pressure heat exchanger system at an intermediate temperature and introduced into the main heat exchanger.
- the high-pressure heat exchanger system has at least two serially connected wound heat exchangers, between which the third partial flow is led out.
- These two serially connected coiled heat exchangers can be realized by two heat exchanger bundles in separate containers or by two serially connected heat exchanger bundles, which are arranged one above the other in the same container.
- the intermediate temperature at which the third partial flow is withdrawn from the high-pressure heat exchanger system and introduced into the main heat exchanger. is between 220 and 120 K, preferably between 190 and 150 K.
- the third partial flow can be conducted separately from the second partial flow through the high-pressure heat exchanger system; Preferably, however, it is guided together with the second partial flow through the warmer of the two wound heat exchanger.
- the high pressure heat exchanger system may also have three or more heat exchanger bundles.
- the first, subcritical pressure of the first feed air stream is preferably equal to the operating pressure of the high pressure column plus line losses and is for example between 5.0 and 6.0 bar, preferably between 5.3 and 5.7 bar.
- a third feed air stream may - optionally after recompression to a third pressure, which is between the first and the second pressure, be expanded in a gaseous state in an air turbine to perform cold work for the process; the inlet temperature of the air turbine is then at an intermediate level between the hot and cold end of the main heat exchanger.
- part of the air compressed to the second, supercritical pressure is released from an intermediate temperature to perform work.
- the total air is compressed to the first, subcritical pressure, pre-cooled and cleaned under this pressure and then divided into the first and second feed air stream. In principle, however, a completely separate compression of the first and the second feed air stream is possible.
- the total air is compressed in a main air compressor to a "first, subcritical pressure" of 6 bar and then pre-cooled and cleaned (not shown).
- the purified feed air 1 is divided into a first feed air stream 100, a second feed air stream 200 and a third feed air stream 300.
- the first feed air stream 100 is introduced under the first pressure in a main heat exchanger 2, flows through this completely from the warm to the cold end.
- the cooled to about dew point temperature first feed air stream 101 is introduced via line 3 in the high pressure column 4 of a distillation column system, which also has a low pressure column 5 and a main capacitor 6.
- the two columns as shown as a classic double column to be arranged one above the other; alternatively they stand side by side.
- the second feed air stream 200 is further compressed in a first after-compressor 7 with aftercooler 8 and further in a second after-compressor 9 with aftercooler 10 to a second, supercritical pressure of 85 bar and then branched again at 201.
- a first partial flow 210/211 of the second feed air stream 200 also flows through the main heat exchanger 2 completely from the hot to the cold end. Not at all through the main heat exchanger 2 flows a second feed air stream 220/221. This is completely cooled in a high-pressure heat exchanger system, which is formed in the embodiment of two coiled heat exchangers 11, 12, which are arranged in separate containers.
- the three sub-streams are reunited and then in a liquid turbine 13 to the operating pressure of the high-pressure column (about 6 bar) doing work relaxed.
- the liquid turbine is braked by a generator 14.
- the working expanded second feed air stream 205 is introduced into the high-pressure column 4 in a predominantly liquid state.
- a third partial stream 230 of the second feed air stream 200 is cooled together with the second partial stream 220 in the warm wound heat exchanger 11 to an intermediate temperature of 165 K and led out via line 203.
- they are further branched and the third substream 230 is fed to the main heat exchanger 2 at an intermediate location corresponding to its temperature and finally cooled there to the cold end.
- the fully cooled third substream 231 is combined at 204 with the remainder of the second feed air stream.
- a third feed air stream 300 is recompressed together with the second feed air stream 200 to a third pressure of 55 bar in the secondary compressor 7 and enters under this pressure in the warm end of the main heat exchanger. At a temperature which is slightly higher than the intermediate temperature of the second partial flow 230, it is removed again and expanded in an air turbine 15 to approximately the operating pressure of the high-pressure column 4 to perform work.
- the air turbine 15 drives the after-compressor 9.
- the expanded turbine air 303 is introduced in gaseous form into the high-pressure column 4 via line 3.
- a liquid oxygen stream 16 from the low-pressure column 5 is brought to a first product pressure in an oxygen pump 17 in the liquid state, which in the example is 115 bar, under this first product pressure in the high-pressure heat exchanger system 12/11 warmed to about ambient temperature and finally recovered as a high pressure oxygen product stream 18.
- the oxygen flows through the interior of the wound tubes of the heat exchangers 11 and 12, the feed air 202 or 206 through their outer space.
- a liquid nitrogen flow 19 from the high-pressure column 4 (it could also be taken from the main condenser 6) is brought in a nitrogen pump 20 in the liquid state to a second product pressure, which is in the embodiment at 80 bar, below this second product pressure to about ambient temperature warmed and finally recovered as a high pressure nitrogen product stream 21.
- a portion of the low-pressure nitrogen 23, 25 can be used for regeneration of the cleaning unit for the feed air (not shown).
- the warm pressure nitrogen can be used as a sealing gas 28 and / or medium-pressure product 29.
