Definitions
- the invention relates to a device for separating carbon dioxide from gases, in particular from exhaust gases.
- WO 2010/086 039 A1 discloses a method and a device for separating carbon dioxide from an exhaust gas from a fossil-fired power plant.
- WO 2014/077 919 A1 discloses a device and a method for removing acidic gases from a gas stream and regenerating the absorbing solution.
- WO 2019/232 626 A1 discloses CO2 separation after combustion with heat recovery. From US 2021/0220771 A1 a carbon dioxide separation downstream of the combustion with a heat recovery is known.
- Carbon dioxide separation with heat recovery is known from CN 208786105 U.
- a carbon dioxide absorber is known from US 2014/0127119 A1.
- US Pat. No. 5,145,658 A discloses the recovery of the heat of reaction from an alkaline scrubbing solution to remove acidic gases.
- the object of the invention is to provide a carbon dioxide separation device in which the overall process of absorption and desorption is energetically optimized.
- the carbon dioxide separation device has an absorption device and a desorption device.
- the gas to be cleaned of carbon dioxide is introduced into the absorption device and the carbon dioxide is converted from the gas phase into the liquid phase by contact with a solvent, usually an amine solution.
- a solution is formed from the solvent with the carbon dioxide dissolved therein, which may be bound.
- This solution is transferred to the desorption device where the carbon dioxide is stripped out of the solution, thereby recovering the solvent and being recycled back to the absorption device.
- a carbon dioxide gas stream is obtained, which can be supplied for further use. This basic principle is already used in a large number of variations.
- the absorption device has a gas inlet for the gas to be cleaned and a gas outlet for the cleaned gas.
- the gas to be cleaned can be, for example, an exhaust gas from the combustion of fossil fuels.
- the cleaned gas would then mostly be mainly nitrogen with a small remainder of carbon dioxide and possibly a greatly reduced proportion of oxygen as a result of the combustion process.
- the cleaned gas can then be released into the atmosphere, for example, without releasing large amounts of carbon dioxide as a greenhouse gas.
- the absorption device usually has one or more mass transfer elements which are arranged between the gas inlet and the absorption solvent inlet.
- the mass transfer elements serve to bring the liquid and the gaseous phase into better contact, in particular also to increase the surface area of the liquid phase.
- Such mass transfer elements are known to those skilled in the art and can, for example, be bubble-cap trays, random packings or structured packing.
- the absorption device further includes an absorption solvent inlet and a solution outlet.
- the absorption solvent inlet is usually located at the top of the absorption device, the solution outlet at the bottom of the absorption device.
- the gas inlet is usually arranged at the bottom and the gas outlet at the top, so that the gas and solvent flow countercurrently through the absorption device.
- the desorption device has at least a first solution inlet, an absorbent solvent outlet, a warm solvent inlet, and a carbon dioxide outlet.
- the solution outlet of the absorber is connected to the first solution inlet connected to the desorption device via a first solution connection.
- the first solution compound has a first heat exchanger. As a result, the solution stream which flows through the first solution connection is heated, so that the carbon dioxide present in the solution can be emitted again in the desorption device.
- the absorption solvent outlet of the desorption device is connected to the absorption solvent inlet of the absorption device via an absorption solvent connection.
- the solvent depleted of carbon dioxide in the desorption device flows back to the absorption device via the absorption solvent connection.
- the absorption solvent compound also has the first heat exchanger.
- the absorption solvent junction has a branch to a warm solvent junction. A partial flow of the solvent flow is therefore branched off and fed into the warm solvent connection.
- the warm solvent connection is connected to the warm solvent inlet.
- the warm solvent compound has a second heat exchanger. As a result, additional energy can be introduced into the entire system.
- the desorption device usually has one or more mass transfer elements which are arranged above and below the first solution inlet. The mass transfer elements serve to bring the liquid and the gaseous phase into better contact, in particular also to increase the surface area of the liquid phase. Such mass transfer elements are known to those skilled in the art and can, for example, be bubble-cap trays, random packings or structured packing.
- a third solution connection branches off between the absorption device and the first heat exchanger of the first solution connection.
- the third solution connection is fluidly connected to the first solution connection after the first heat exchanger or absorption device at the end where the solution flow exits the third solution connection again.
- the third solution compound has a fourth heat exchanger in which the solution stream of the third solution compound is heated.
- the fourth heat exchanger and the gas inlet are connected via a gas connection, so that the gas to be cleaned is passed through the fourth heat exchanger before the gas to be cleaned is passed into the absorption device.
- the gas to be cleaned with a Temperature between 100 ° C and 200 ° C, for example 150 ° C, provided, according to how it is obtained from the preliminary processes.
- the first solution connection has an evaporation device downstream of the first heat exchanger in terms of flow.
- the evaporation device also known as the pressure expansion tank, is used to allow the solution of the solution stream heated in the first heat exchanger to expand and therefore partially evaporate.
- the liquid phase of the solution stream is thus separated from the gaseous phase of the solution stream in the evaporation device.
- the liquid phase is led into the desorption device through the first solution connection.
- the desorption device further has a vapor inlet and the evaporation device has a vapor outlet.
- the vapor outlet of the evaporation device and the vapor inlet of the desorption device are connected to a gas solution connection for transfer of the gaseous phase.
- the steam inlet is particularly preferably arranged in the lower region of the desorption device. This optimizes the energetic management of the overall process.
- the third solution connection is connected to the evaporation device at the end where the solution stream emerges again from the third solution connection.
- the gas connection has a raw gas cleaning system.
- the raw gas cleaning is designed to remove sulfur oxides.
- a second solution connection branches off between the absorption device and the first heat exchanger of the first solution connection.
- the second solution connection leads directly to the top of the desorption device.
- directly means without a heat exchanger or the like.
- a (flow control) valve can be arranged here.
- the solution loaded with carbon dioxide is thus itself used to cool the gas stream exiting the desorption device.
- the heat supplied from the first heat exchanger and the second heat exchanger into the desorption device remains in the desorption device and the solvent and is not released to a cooling medium.
- a fourth solution connection branches off between the absorption device and the first heat exchanger of the first solution connection.
- the fourth solution connection is connected to the first solution connection after the first heat exchanger or absorption device at the end where the solution flow exits the fourth solution connection again.
- the fourth solution compound has a fifth heat exchanger.
- the fifth heat exchanger is connected to the second heat exchanger in such a way that the heat exchange medium cooled in the second heat exchanger is fed into the fifth heat exchanger.
- the fourth solution connection is connected to the evaporation device at the end where the solution stream exits the fourth solution connection again.
- the carbon dioxide outlet is connected to a first carbon dioxide compressor.
- the first carbon dioxide compressor is connected to a first carbon dioxide heat exchanger in order to cool down the carbon dioxide heated by the compression again. This is common, since the carbon dioxide is required at a higher pressure both for dumping and for the further processing of carbon dioxide, for example to form methanol.
- a plurality of carbon dioxide compressors and carbon dioxide heat exchangers are usually connected in series in a cascaded manner in order to compress the carbon dioxide in stages and to cool it again and again in between.
- a fifth solution connection branches off between the absorption device and the first heat exchanger of the first solution connection.
- the fifth solution connection is connected to the first solution connection after the first heat exchanger or absorption device at the end where the solution flow exits the fifth solution connection again.
- the fifth solution compound includes the first carbon dioxide heat exchanger. This allows the thermal energy generated by compressing the carbon dioxide to be used for the process. If there is a plurality of carbon dioxide heat exchangers, these are preferably integrated in parallel into the fifth solution compound.
- the fifth solution connection is connected to the evaporation device at the end where the solution stream emerges again from the fifth solution connection. In this way, as in the case of the heated solution stream of the first solution compound, expansion can take place here and the gas phase can be separated from the liquid phase.
- the pressure of the solvent in the second heat exchanger is 0.2 bar to 5 bar higher than the pressure in the desorption device at the absorption solvent outlet.
- a higher starting temperature can thus be achieved in the second heat exchanger, since the increased pressure allows the temperature to be increased up to the boiling point at the corresponding pressure.
- the solvent has a higher temperature at the absorption solvent outlet and thus reaches the first heat exchanger at a higher temperature.
- this can either be made more compact or a higher starting temperature for the loaded solution stream can be achieved from the first heat exchanger. The latter in turn leads to more efficient expulsion of the carbon dioxide from the solution.
- the pressure of the solvent in the second heat exchanger is dependent on the equipment.
- the pressure of the solvent in the second heat exchanger is higher by 0.2 bar to 5 bar than the pressure in the desorption device at the absorption solvent outlet in that the second heat exchanger is arranged at least 1 m below the absorption solvent outlet, whereby the pressure in the second heat exchanger is generated by the hydrostatic pressure of the liquid column of the solvent.
- the pressure of the solvent in the second heat exchanger is 0.2 bar to 5 bar higher than the pressure in the desorption device at the absorption solvent outlet by arranging a first pump upstream of the second heat exchanger to generate the corresponding overpressure is.
- a pressure loss device for example a control valve, an orifice plate or a tube constriction, is arranged between the second heat exchanger and the desorption device.
- the pressure loss device With the pressure loss device, the desired overpressure in the second gas/steam heat exchanger is set or maintained on the gas/steam side. In this way, if necessary, evaporation can already be prevented in the second heat exchanger.
- the first solution inlet is preferably arranged in the middle region of the desorption device.
- 3 third exemplary embodiment 1 shows a first exemplary embodiment of a carbon dioxide separation device 10 according to the invention.
- the carbon dioxide separation device 10 is used, for example, to separate the carbon dioxide from an exhaust gas stream, which enters the gas inlet 21 and is greatly depleted in carbon dioxide and exits at the gas outlet 22 .
- this gas flow is brought into contact with a solvent, usually an amine solution, in countercurrent, so that the carbon dioxide dissolves.
- This solution exits the absorption device at the solution outlet 24 and is pumped through the first solution connection 40 by a second pump 46 .
- the first solution compound 40 has a first heat exchanger 41 in which the solution flow is heated by the solvent flow of the absorption solvent compound 50 .
- evaporation device 42 Downstream of the first heat exchanger 41 is an evaporation device 42 in which the solution can partially convert into the gas phase.
- the liquid phase of the solution stream is conveyed further through the first solution connection 40, for example by means of a third pump 47 through the first solution inlet 31 into the desorption device 30.
- the gas produced in the evaporation device 42 is conducted through the vapor outlet 43 into the gas dissolving connection 44 and through this via the vapor inlet 35 into the desorption device 30 .
- the steam inlet 35 is preferably located at the lower end, the bottom, of the desorption device 30.
- the carbon dioxide is thermally removed from the solution and discharged via the carbon dioxide outlet 34 .
- This carbon dioxide stream can then be fed, for example, either to a further reaction or to landfill.
- the solvent freed from carbon dioxide collects at the bottom of the desorption device 30 and is supplied to the absorption solvent joint 50 through the absorption solvent outlet 32 .
- the solvent flow transfers its thermal energy to the solution flow in the first heat exchanger 41 .
- the solvent stream reaches the absorption device via a third heat exchanger 55 through the absorption solvent inlet 23 .
- a partial flow branches off from the solvent flow in the absorption solvent connection 50 at the junction 51 and is conveyed through the warm solvent connection 52 via the second heat exchanger 53, in particular in vapor form or as a vapour/liquid mixture, through the warm solvent inlet 33 back into the desorption device 30.
- the energy required for expelling the carbon dioxide from the solution is supplied to the system via the second heat exchanger 53 .
- a third solution connection 60 which has a fourth heat exchanger 61 , also branches off from the first solution connection 40 .
- the third solution connection 60 opens into the evaporation device 42 at the end.
- the fourth heat exchanger 61 and the gas inlet 21 of the absorption device 20 are connected via the gas connection 25 .
- the gas connection 25 also has a raw gas cleaning 26, in which SO X is removed and also brings the gas flow to the right temperature for the absorption of the carbon dioxide in the absorption device 20.
- FIG. 2 shows a second exemplary embodiment, which differs from the first exemplary embodiment in that a fourth solution connection 62 is also present, which conducts a partial flow of the solution flow in via the fifth heat exchanger 63 into the evaporation device 42 .
- the energy for heating the solution stream in the fifth heat exchanger 63 comes from the heat exchange medium that has already been cooled in the second heat exchanger 53, and whose residual heat is used efficiently as a result.
- FIG. 10 A third exemplary embodiment is shown in FIG. In addition to the second exemplary embodiment, FIG.
- the carbon dioxide separation device 10 has a fifth solution connection 64 which leads a partial flow of the solution flow through the carbon dioxide heat exchanger 37 into the evaporation device 42 .
