[0007] In the above Patent Documents 1 and 2, carbon dioxide is recovered from a gaseous carbon dioxide supply source by simultaneously and continuously carrying out a carbon dioxide absorption step and a carbon dioxide desorption step.

[0008] However, depending on the operation of the factory, for example, in the case of a facility that operates only during the day and shuts down at night, the gaseous carbon dioxide source is not discharged at night, so the carbon dioxide recovery equipment must be shut down, resulting in low operation rates. Alternatively, there may be cases where it is desired to gradually increase the carbon dioxide recovery from the factory's gaseous carbon dioxide source to increase the processing volume depending on the situation. Furthermore, because the gaseous carbon dioxide source is low-pressure, large pieces of equipment will be required for the recovery equipment, and it is expected that the factory site will already be filled and there will not be enough space to install all of the equipment for the recovery equipment.

[0009] Furthermore, simply capturing carbon dioxide, which has little utility value and is otherwise released into the atmosphere and discarded, would only increase the cost of capturing it, making it commercially unviable.

[0010] Therefore, there is a need for a carbon dioxide recovery system that can grasp the demand for carbon dioxide and control the amount of carbon dioxide recovered.

[0011] Therefore, an object of the present invention is to provide a carbon dioxide recovery system that can adjust the amount of carbon dioxide recovered in accordance with the demand for carbon dioxide. [Means for solving the problem]

[0024] The system for recovering and managing carbon dioxide in a gaseous carbon dioxide supply source of the present invention (1) will be described with reference to Fig. 1. Fig. 1 is a schematic flow diagram showing an example of the system for recovering and managing carbon dioxide in a gaseous carbon dioxide supply source of the present invention (1).

[0025] In FIG. 1, the carbon dioxide recovery management system 10a in a gaseous carbon dioxide supply source has at least a first-class factory 1, a second-class factory 2, a server 4, a carbon dioxide-rich absorption liquid transport means (1) 11, a carbon dioxide-lean absorption liquid transport means (1) 14, and a carbon dioxide transport means (1) 12.

[0026] The first-class factory 1 is equipped with an absorption tower, a carbon dioxide-lean absorbing liquid storage tank, and a carbon dioxide-rich absorbing liquid storage tank. In the absorption tower, the first-class factory 1 performs an absorption step (1) in which carbon dioxide in a gaseous carbon dioxide supply source containing carbon dioxide is reactively absorbed by the carbon dioxide-lean absorbing liquid, and the resulting carbon dioxide-rich absorbing liquid is sent to the carbon dioxide-rich absorbing liquid storage tank and stored. The absorption step (1) is a step in which the gaseous carbon dioxide supply source discharged from an apparatus in the first-class factory 1 is supplied to the absorption tower, and the carbon dioxide-lean absorbing liquid is supplied from the carbon dioxide-lean absorbing liquid storage tank installed in the first-class factory 1. The gaseous carbon dioxide supply source and the carbon dioxide-lean absorbing liquid come into contact with each other in the absorption tower, causing the carbon dioxide in the gaseous carbon dioxide supply source to react with an absorbent, such as an amine compound, contained in the carbon dioxide-lean absorbing liquid and reactively absorbed by the carbon dioxide-lean absorbing liquid, producing a carbon dioxide-rich absorbing liquid. The carbon dioxide-rich absorbing liquid produced by the reactive absorption is then sent to the carbon dioxide-rich absorbing liquid storage tank and stored.

[0027] The absorption tower, carbon dioxide-lean absorption liquid storage tank, and carbon dioxide-rich absorption liquid storage tank installed in the first-class factory 1 are not particularly limited, and are appropriately selected depending on the supply amount of the gaseous carbon dioxide supply source, the pressure and carbon dioxide concentration, the supply amount of the carbon dioxide-lean absorption liquid, the type of absorption liquid and absorbent contained in the absorption liquid, the production amount of the carbon dioxide-rich absorption liquid, the retained amount of the carbon dioxide-lean absorption liquid, the retained amount of the carbon dioxide-rich absorption liquid, etc.

[0028] A regeneration tower, a carbon dioxide-lean absorbing solution storage tank, and a carbon dioxide-rich absorbing solution storage tank are installed in the second-class factory 2. The second-class factory 2 performs a "regeneration step (1) in which the carbon dioxide-rich absorbing solution is heated in the regeneration tower, thereby desorbing carbon dioxide from the carbon dioxide-rich absorbing solution and regenerating a carbon dioxide-lean absorbing solution made of an amine compound, and then the desorbed carbon dioxide is recovered, and the carbon dioxide-lean absorbing solution is sent to the carbon dioxide-lean absorbing solution storage tank and stored therein."

[0029] The regeneration step (1) is a step in which a carbon dioxide-rich absorbing solution is supplied to the regeneration tower from a carbon dioxide-rich absorbing solution storage tank installed in the second-class factory 2, and the carbon dioxide-rich absorbing solution is heated in the regeneration tower to desorb carbon dioxide from the carbon dioxide-rich absorbing solution, thereby regenerating a carbon dioxide-lean absorbing solution made of an amine compound, and then the desorbed carbon dioxide is recovered, and the carbon dioxide-lean absorbing solution produced by the desorption of carbon dioxide is sent to the carbon dioxide-lean absorbing solution storage tank and stored therein.

[0030] The regeneration tower, carbon dioxide lean absorption liquid storage tank, and carbon dioxide rich absorption liquid storage tank installed in the second type factory 2 are not particularly limited, and are selected appropriately depending on the amount of carbon dioxide produced, the amount of carbon dioxide lean absorption liquid produced, the amount of carbon dioxide rich absorption liquid held, the amount of carbon dioxide lean absorption liquid held, etc.

[0031] The carbon dioxide-rich absorbing liquid transport means (1) 11 is a means for transporting the carbon dioxide-rich absorbing liquid in the carbon dioxide-rich absorbing liquid storage tank installed in the first-class factory 1 to the carbon dioxide-rich absorbing liquid storage tank installed in the second-class factory 2.

[0032] The carbon dioxide-rich absorbing liquid transport means (1) 11 is not particularly limited as long as it is capable of transporting the carbon dioxide-rich absorbing liquid from the first-class factory 1 to the second-class factory 2, and examples thereof include mobile objects such as tank trucks, ships, and tank cars, and pipelines connecting the carbon dioxide-rich absorbing liquid storage tank of the first-class factory 1 and the carbon dioxide-rich absorbing liquid storage tank of the second-class factory 2.

[0033] The carbon dioxide lean absorption liquid transport means (1) 14 is a means for transporting the carbon dioxide lean absorption liquid in the carbon dioxide lean absorption liquid storage tank installed in the second type factory 2 to the carbon dioxide lean absorption liquid storage tank installed in the first type factory 1.

[0034] The carbon dioxide lean absorption liquid transport means (1) 14 is not particularly limited as long as it is capable of transporting the carbon dioxide lean absorption liquid from the second-class factory 2 to the first-class factory 1, and examples thereof include mobile objects such as tank trucks, ships, and tank cars, and pipelines connecting the carbon dioxide lean absorption liquid storage tank of the first-class factory 1 and the carbon dioxide lean absorption liquid storage tank of the second-class factory 2.

[0035] The carbon dioxide transport means (1) 12 is a means for transporting the carbon dioxide recovered in the second type factory 2 to the carbon dioxide consuming factory.

[0036] The carbon dioxide transport means (1) 12 is not particularly limited as long as it is capable of transporting carbon dioxide from the second-class factory 2 to the carbon dioxide consuming factory, and examples include a pipeline, a tanker truck, a freight tank car, etc. that connects the carbon dioxide discharge pipe of the absorption and regeneration tower of the second-class factory 2 or the carbon dioxide storage tank installed in the second-class factory 2 to the carbon dioxide receiving tank of the carbon dioxide consuming factory or a reaction device for a reaction using carbon dioxide as a raw material.

[0037] Carbon dioxide-consuming factories use carbon dioxide as a raw material to produce various chemical products, minerals, artificial photosynthesis, plant factories, carbon capture and storage (CCS), bioenergy carbon capture and storage (BECCS), etc. For example, carbon dioxide-consuming factories produce oxo (CO / H) synthesis gas, engine materials such as methanol and dimethyl ether (DME), polycarbonate, urethane, biomass-derived chemicals, commodity chemicals such as ethylene / propylene / butene (olefins) and benzene / toluene / xylene (BTX), fuels such as biojet fuel from microalgae, biodiesel fuel, methane fuel, and bioalcohol fuel, and minerals such as concrete structures, paving materials, and carbonates.

[0038] The server 4 has a receiving unit and a calculation unit, and is connected to the computers installed in the first-class factory 1, the second-class factory 2, and the carbon dioxide consuming factory 5 via a computer network made up of high-speed communication lines and an LPWA communication system. In Figure 1, the connections via the computer network made up of high-speed communication lines and an LPWA communication system are shown with dotted lines. Examples of computer networks made up of high-speed communication lines and an LPWA communication system include computer networks using optical fiber, LAN, wireless, and dedicated lines. LPWA communication is an abbreviation for Low Power Wide Area network (the same applies below).

[0039] The receiving section of the server 4 receives management data transmitted from the computer installed in the first-class factory 1, management data transmitted from the computer installed in the second-class factory 2, data on the required amount of carbon dioxide transmitted from the carbon dioxide consuming factory 5, and mobile object location information transmitted from the transportation means.

[0040] The management data transmitted from the first-class factory 1 to the receiving unit of the server 4 is data necessary for the calculation unit of the server 4 to calculate the amount of carbon dioxide-rich absorbing liquid to be transported from the first-class factory 1 to the second-class factory 2, and the target amount of carbon dioxide lean absorbing liquid and carbon dioxide produced in the regeneration process (1) at the second factory 2, and is, for example, the flow rate of the carbon dioxide-rich absorbing liquid produced in the absorption tower at the first class factory, the storage amount of the carbon dioxide-rich absorbing liquid, the carbon dioxide content of the carbon dioxide-rich absorbing liquid, the storage amount of the carbon dioxide-lean absorbing liquid, the number of vehicles or ships of carbon dioxide-rich absorbing liquid transport means or carbon dioxide-lean absorbing liquid transport means, etc.

[0041] The management data transmitted from the second-class factory 2 to the receiving unit of the server 4 is data necessary for the calculation unit of the server 4 to calculate the amount of carbon dioxide lean absorption liquid to be transported from the second-class factory 2 to the first-class factory 1, and the target amount of carbon dioxide lean absorption liquid and carbon dioxide produced in the regeneration process (1) at the second-class factory, such as the flow rate of the carbon dioxide lean absorption liquid produced in the regeneration tower at the second-class factory, the storage amount of carbon dioxide-rich absorption liquid, the carbon dioxide content in the carbon dioxide lean absorption liquid and the storage amount of carbon dioxide lean absorption liquid, the number of carbon dioxide-rich absorption liquid transport means or carbon dioxide lean absorption liquid transport means dispatched or the number of dispatched ships, etc.

[0042] The data on the required amount of carbon dioxide transmitted from the carbon dioxide consuming factory 5 is a predicted value of the demand for carbon dioxide calculated based on the carbon dioxide demand forecast at the carbon dioxide consuming factory 5. This predicted value of the demand for carbon dioxide is calculated by the server 4 based on production forecasts or past performance data for periods such as a year, month, or week.

[0043] The calculation unit of the server 4 compares the management data sent from the first factory 1 and received by the receiving unit, the management data (actual measured value) sent from the second factory 2 and received by the receiving unit, the data (predicted value) on the required amount of carbon dioxide sent from the carbon dioxide consuming factory 5 and received by the receiving unit, and the mobile object position information sent from the transportation means, to calculate the amount of carbon dioxide-rich absorption liquid to be transported from the first factory 1 to the second factory 2, the amount of carbon dioxide-lean absorption liquid to be transported from the second factory 2 to the first factory 1, and the target amount of carbon dioxide to be produced in the regeneration process (1) at the second factory 2, and transmits the data on the amount of carbon dioxide-rich absorption liquid to the computer of the first factory 1, and transmits the data on the amount of carbon dioxide-lean absorption liquid to the computer of the second factory 2, and the data on the amount of carbon dioxide-lean absorption liquid to be transported, and the target amount of carbon dioxide to be produced in the regeneration process (1).

[0044] Then, based on the data on the transport amount of the carbon dioxide-rich absorbing solution transmitted from the server 4, the carbon dioxide-rich absorbing solution is transported from the first type factory 1 to the second type factory 2. Also, based on the transport amount data of the carbon dioxide-lean absorbing solution transmitted from the server 4, the carbon dioxide-lean absorbing solution is transported from the second type factory 2 to the first type factory 1. Also, at the second type factory 2, based on the data on the carbon dioxide-lean absorbing solution and the target production amount of carbon dioxide in the regeneration step (1) transmitted from the server 4, the regeneration step (1) is performed so as to achieve the target production amount.

[0045] In the (1) system for recovering and managing carbon dioxide in a gaseous carbon dioxide supply source of the present invention, both the carbon dioxide-lean absorbing liquid and the carbon dioxide-rich absorbing liquid are absorbing liquids containing an absorbent. The carbon dioxide-lean absorbing liquid is an absorbing liquid from which carbon dioxide has been desorbed in the regeneration step and from which the amount of carbon dioxide absorbed is small. On the other hand, the carbon dioxide-rich absorbing liquid is an absorbing liquid from which carbon dioxide has been absorbed in the absorption step and from which the amount of carbon dioxide absorbed is large.

[0046] The absorbing liquid is not particularly limited as long as it can absorb carbon dioxide from a gaseous carbon dioxide supply source at 90 to 300 kPa, preferably 90 to 130 kPa.

[0047] Examples of absorbents contained in the absorbing solution include all amine compounds, such as alkanolamines such as monoethanolamine, diethanolamine, diisopropanolamine, dimethyldiethanolamine, and triethanolamine, amino alcohols such as aminodiethylene glycol, hindered amine compounds, piperazine compounds, piperidine compounds, polyalkylpolyamine compounds, amino acid compounds, amino acid salt compounds, and derivatives thereof, as well as organic amine compounds. The absorbent may be one type or a combination of two or more of the above types in any mixing ratio. Preferred absorbents have a high absorption rate, a large carbon dioxide absorption capacity, are thermally stable, and require little energy for regeneration.

[0048] The carbon dioxide cyclic loading amount of the absorbent contained in the absorption liquid is preferably 0.85 mol (CO2) / L (solution) or more, particularly preferably 2.0 to 7.0 mol (CO2) / L (solution). When the carbon dioxide cyclic loading amount of the absorbent is within the above range, the amount of circulation of the absorption liquid is reduced, and the required area for installing the equipment can be reduced. In the present invention, the carbon dioxide cyclic loading amount of the absorbent is calculated by the following formula. Carbon dioxide cyclic loading of absorbent (moles (CO2) / L (solution)) = carbon dioxide absorption at 40°C and 20 kPa (moles (CO2) / L (solution)) - carbon dioxide absorption at 120°C and 100 kPa (moles (CO2) / L (solution))

[0049] The carbon dioxide absorption rate of the absorbent contained in the absorbing solution is preferably 0.09 mol (CO2) / L (solution) per minute or more, particularly preferably 0.10 to 0.20 mol (CO2) / L (solution) per minute. When the carbon dioxide absorption rate of the absorbent is within the above range, reactive absorption of carbon dioxide in the absorption step is promoted, and the height of the absorption and regeneration tower can be reduced.

[0050] The carbon dioxide desorption energy of the absorbent contained in the absorbing solution is preferably 90 kJ / mol (CO2) or less, particularly preferably 30 to 75 kJ / mol (CO2). When the carbon dioxide desorption energy of the absorbent is within the above range, carbon dioxide desorption in the regeneration step occurs more easily, and the required energy can be kept low.

[0051] The absorbing liquid is, for example, an aqueous solution of an absorbent. The absorbing liquid is preferably an aqueous solution of alkanolamine, and particularly preferably an aqueous solution of alkanolamine with a concentration of 15 to 45% by mass.

[0052] In the system for recovering and managing carbon dioxide in a gaseous carbon dioxide supply source of the present invention, the location of the server 4 is not particularly limited, and may be inside or outside Japan.

[0053] The gaseous carbon dioxide supply source for the absorption step is a gas containing carbon dioxide. Examples of the gaseous carbon dioxide supply source include exhaust gases emitted from equipment such as blast furnaces, lime kilns, heating furnaces, reactors, and boilers in power plants, steel mills, cement plants, oil refineries, and chemical plants. Another example of the gaseous carbon dioxide supply source is the atmosphere.

[0054] The carbon dioxide concentration in the gaseous carbon dioxide supply source for the absorption step is 50.0% by volume or less, preferably 2.0 to 25.0% by volume, and particularly preferably 2.0 to 20.0% by volume. The pressure of the gaseous carbon dioxide supply source supplied to the absorption tower is 90 to 300 kPa, and preferably 90 to 130 kPa.

[0055] The carbon dioxide recovery and management system of the present invention for a gaseous carbon dioxide supply source further includes: An absorption and regeneration tower, a carbon dioxide lean absorption liquid storage tank, and a carbon dioxide rich absorption liquid storage tank are installed, and a gaseous carbon dioxide supply source containing carbon dioxide and the carbon dioxide lean absorption liquid in the carbon dioxide lean absorption liquid storage tank are supplied to the absorption and regeneration tower, and the gaseous carbon dioxide supply source and the carbon dioxide lean absorption liquid come into contact with each other in the absorption and regeneration tower, whereby the carbon dioxide in the gaseous carbon dioxide supply source is absorbed by the carbon dioxide lean absorption liquid to produce a carbon dioxide rich absorption liquid, and then the carbon dioxide rich absorption liquid is converted into a carbon dioxide rich and one or more third-class factories in which an absorption step (2) in which the carbon dioxide-rich absorbing liquid is sent to an absorbing liquid storage tank and stored therein, and a regeneration step (2) in which the carbon dioxide-rich absorbing liquid in the carbon dioxide-rich absorbing liquid storage tank is supplied to the absorption and regeneration tower, the carbon dioxide-rich absorbing liquid is heated in the absorption and regeneration tower, thereby desorbing carbon dioxide from the carbon dioxide-rich absorbing liquid and regenerating the carbon dioxide-lean absorbing liquid, and then the desorbed carbon dioxide is recovered, and the carbon dioxide-lean absorbing liquid is sent to the carbon dioxide-lean absorbing liquid storage tank and stored therein are alternately repeated. a carbon dioxide-rich absorbing liquid transport means (2) for transporting the carbon dioxide-rich absorbing liquid in the carbon dioxide-rich absorbing liquid storage tank installed in the first-class factory to the carbon dioxide-rich absorbing liquid storage tank installed in the third-class factory; a carbon dioxide lean absorbing liquid transport means (2) for transporting the carbon dioxide lean absorbing liquid in the carbon dioxide lean absorbing liquid storage tank installed in the third-class factory to the carbon dioxide lean absorbing liquid storage tank installed in the first-class factory; a carbon dioxide transport means (2) for transporting the carbon dioxide recovered at the third-class factory to a carbon dioxide consuming factory where the carbon dioxide is consumed; and The receiving unit of the server further receives management data transmitted from the third-class factory and mobile body position information transmitted from the transport means, and the calculation unit of the server further calculates, from the data received by the receiving unit, the amount of the carbon dioxide-rich absorbing solution transported from the first-class factory to the third-class factory, the amount of the carbon dioxide-lean absorbing solution transported from the third-class factory to the first-class factory, the target production amount of the carbon dioxide-rich absorbing solution in the absorption step (2) at the third-class factory and the carbon dioxide-lean absorbing solution in the regeneration step (2). and a calculation unit that calculates the target production amount of the carbon dioxide-rich absorbing liquid and the target production amount of carbon dioxide, and transmits data on the transport amount of the carbon dioxide-lean absorbing liquid to the first type factory, and transmits data on the transport amount of the carbon dioxide-lean absorbing liquid, the target production amount of the carbon dioxide-rich absorbing liquid in the absorption step (2), and the target production amounts of the carbon dioxide-lean absorbing liquid and carbon dioxide in the regeneration step (2) to the third type factory (hereinafter also referred to as modified form (1) of the present invention (1)).

[0129] Then, based on the data on the transport amount of the carbon dioxide-rich absorbing solution transmitted from the server 4, the carbon dioxide-rich absorbing solution is transported from the first type factory 1 to the second type factory 2 or from the first type factory 1 to the third type factory 3.

[0130] In the embodiment shown in Figures 1 to 5, the number of type 1 factories is three, but the carbon dioxide recovery and management system in the gaseous carbon dioxide supply source of the present invention (1) is not limited to this, and the number of type 1 factories may be one or more. Also, in the embodiment shown in Figures 1 to 5, the number of type 2 factories is one, but the carbon dioxide recovery and management system in the gaseous carbon dioxide supply source of the present invention (1) is not limited to this, and the number of type 2 factories may be one or more. Also, in the embodiment shown in Figures 1 to 5, the number of carbon dioxide consuming factories is one, but the carbon dioxide recovery and management system in the gaseous carbon dioxide supply source of the present invention (1) is not limited to this, and the number of carbon dioxide consuming factories may be one or more. Also, in the embodiment shown in Figures 2 and 5, the number of type 3 factories is one, but the carbon dioxide recovery and management system in the gaseous carbon dioxide supply source of the present invention (1) is not limited to this, and the number of type 3 factories may be one or more. In addition, in the embodiments shown in Figures 3, 4 and 5, the number of fourth-class factories is one, but the carbon dioxide recovery management system in the gaseous carbon dioxide supply source of the present invention (1) is not limited to this, and the number of fourth-class factories may be one or more.

[0131] In the carbon dioxide recovery management system for a gaseous carbon dioxide supply source of the present invention (1), the server can further calculate a target production amount of the carbon dioxide-rich absorption liquid at the first-class factory and transmit data on the target production amount of the carbon dioxide-rich absorption liquid to the first-class factory.

[0132] In the carbon dioxide recovery system in the gaseous carbon dioxide supply source of the present invention (1), the server can further compare the data with the operation plan of each factory and transmit corrected operation management data to each factory based on the analysis results of the supply and demand balance.

[0133] In the present invention, the target production amount refers to the quantities of carbon dioxide-rich absorption solution, carbon dioxide-lean absorption solution, and carbon dioxide required to maintain the balance between supply and demand of carbon dioxide in the carbon dioxide recovery management system in the gaseous carbon dioxide supply source of the present invention (1).

[0134] In the carbon dioxide recovery management system for a gaseous carbon dioxide supply source of the present invention (1), the timing of transmitting data such as the amount of carbon dioxide-rich absorbing solution to be transported, the carbon dioxide-rich absorbing solution, the carbon dioxide-lean absorbing solution, and the target amount of carbon dioxide produced from the server to each factory is not particularly limited, and examples thereof include sequentially, at a fixed time such as once a day, or when requested by each factory.

[0135] In the carbon dioxide recovery management system for a gaseous carbon dioxide supply source of the present invention (1), the timing of transmission of each management data from the computer of each factory to the server is not particularly limited, and examples include sequentially, at a fixed time such as once a day, or when requested by each factory.

[0136] In the carbon dioxide recovery system in a gaseous carbon dioxide supply source of the present invention (1), the amount of carbon dioxide produced in the regeneration step (2) in the second factory is adjusted so that carbon dioxide is produced in accordance with the required amount of carbon dioxide based on a carbon dioxide demand forecast at the carbon dioxide consuming factory, and the amount of carbon dioxide-rich absorbing liquid produced in the absorption step (1) in the first factory is adjusted so that the amount of carbon dioxide-rich absorbing liquid required to perform the regeneration step (2) is produced.The amount of carbon dioxide-rich absorbing liquid transported from the first factory to the second factory and the amount of carbon dioxide-lean absorbing liquid transported from the second factory to the first factory can be adjusted so that the amounts of carbon dioxide-rich absorbing liquid and carbon dioxide-lean absorbing liquid required to perform these steps are present at the first factory and second factory, so that the amounts of carbon dioxide-rich absorbing liquid and carbon dioxide-lean absorbing liquid required to perform these steps can be adjusted.Therefore, the amount of carbon dioxide recovered from each of the first and second factory can be managed comprehensively according to the carbon dioxide demand.

[0137] Furthermore, since the operating conditions and operating schedules of the combustion equipment differ for each factory that captures carbon dioxide, the amount of carbon dioxide-rich absorbing solution produced at each factory is constantly fluctuating. Therefore, if the amount of carbon dioxide-rich absorbing solution delivered to each factory, the target amount of carbon dioxide-rich absorbing solution, carbon dioxide-lean absorbing solution, and carbon dioxide production, etc., were always the same, comprehensive management would not be possible. In the carbon dioxide capture system for a gaseous carbon dioxide supply source of the present invention (1), the operating conditions and operating schedules of the combustion equipment at each factory are taken into consideration, and the amount of carbon dioxide-rich absorbing solution delivered to each factory, the target amount of carbon dioxide-rich absorbing solution, carbon dioxide-lean absorbing solution, and carbon dioxide production, and correction of the delivery amount based on the position information of the mobile body used as delivery means, etc. can be calculated accordingly. Therefore, the carbon dioxide capture method can be comprehensively managed.

[0141] The first-class factory 1 is equipped with an absorption tower, a carbon dioxide-lean absorbing liquid storage tank, and a carbon dioxide-rich absorbing liquid storage tank. In the absorption tower, the first-class factory 1 performs an absorption step (1) in which carbon dioxide in a gaseous carbon dioxide supply source containing carbon dioxide is reactively absorbed by the carbon dioxide-lean absorbing liquid, and the resulting carbon dioxide-rich absorbing liquid is sent to the carbon dioxide-rich absorbing liquid storage tank and stored. The absorption step (1) is a step in which the gaseous carbon dioxide supply source discharged from an apparatus in the first-class factory 1 is supplied to the absorption tower, and the carbon dioxide-lean absorbing liquid is supplied from the carbon dioxide-lean absorbing liquid storage tank installed in the first-class factory 1. The gaseous carbon dioxide supply source and the carbon dioxide-lean absorbing liquid come into contact with each other in the absorption tower, causing the carbon dioxide in the gaseous carbon dioxide supply source to react with an absorbent, such as an amine compound, contained in the carbon dioxide-lean absorbing liquid and reactively absorbed by the carbon dioxide-lean absorbing liquid, producing a carbon dioxide-rich absorbing liquid. The carbon dioxide-rich absorbing liquid produced by the reactive absorption is then sent to the carbon dioxide-rich absorbing liquid storage tank and stored.

[0142] The absorption tower, carbon dioxide-lean absorption liquid storage tank, and carbon dioxide-rich absorption liquid storage tank installed in the first-class factory 1 are not particularly limited, and are appropriately selected depending on the supply amount of the gaseous carbon dioxide supply source, the pressure and carbon dioxide concentration, the supply amount of the carbon dioxide-lean absorption liquid, the type of absorption liquid and absorbent contained in the absorption liquid, the production amount of the carbon dioxide-rich absorption liquid, the retention amount of the carbon dioxide-lean absorption liquid, the retention amount of the carbon dioxide-rich absorption liquid, etc.

[0143] The third-class factory 3 is equipped with an absorption and regeneration tower, a carbon dioxide-lean absorbing liquid storage tank, and a carbon dioxide-rich absorbing liquid storage tank. The third-class factory 3 performs an absorption process (2) in which carbon dioxide in a gaseous carbon dioxide supply source containing carbon dioxide is reactively absorbed by the carbon dioxide-lean absorbing liquid in the absorption and regeneration tower, and the carbon dioxide-rich absorbing liquid produced is sent to the carbon dioxide-rich absorbing liquid storage tank and stored therein, and a regeneration process (2) in which the carbon dioxide-rich absorbing liquid is heated in the absorption and regeneration tower, thereby desorbing carbon dioxide from the carbon dioxide-rich absorbing liquid and regenerating a carbon dioxide-lean absorbing liquid composed of an amine compound, and then the desorbed carbon dioxide is recovered, and the carbon dioxide-lean absorbing liquid is sent to the regenerated absorbing liquid storage tank and stored therein.

[0145] The regeneration step (2) is a step in which the carbon dioxide-rich absorbing liquid is supplied to the absorption and regeneration tower from a carbon dioxide-rich absorbing liquid storage tank installed in the third-class factory 3, the carbon dioxide-rich absorbing liquid is heated in the absorption and regeneration tower, the carbon dioxide in the carbon dioxide-rich absorbing liquid is desorbed, and a carbon dioxide-lean absorbing liquid consisting of an amine compound is regenerated, and then the desorbed carbon dioxide is recovered, and the carbon dioxide-lean absorbing liquid produced by the desorption of carbon dioxide is sent to the carbon dioxide-lean absorbing liquid storage tank and stored therein.

[0146] In the third type factory 3, the absorption step (2) and the regeneration step (2) are alternately and repeatedly performed. In the third type factory 3, the time ratio for performing the absorption step (2) and the regeneration step (2) is appropriately selected depending on the amount of carbon dioxide required by the carbon dioxide consuming factory, the amount of carbon dioxide-rich absorbing solution transported from the first type factory 1, the amount and expected amount of carbon dioxide-rich absorbing solution produced in the third type factory 3, changes over time, etc.

[0147] The absorption and regeneration tower, carbon dioxide lean absorption liquid storage tank and carbon dioxide rich absorption liquid storage tank installed in the third type factory 3 are not particularly limited, and are appropriately selected depending on the supply amount of the gaseous carbon dioxide supply source, the pressure and carbon dioxide concentration, the supply amount of the carbon dioxide lean absorption liquid, the type of amine compound constituting the carbon dioxide lean absorption liquid, the production amount of the carbon dioxide rich absorption liquid, the retention amount of the carbon dioxide lean absorption liquid, the retention amount of the carbon dioxide rich absorption liquid, etc.

[0148] The carbon dioxide-rich absorbing liquid transport means (1) 11 is a means for transporting the carbon dioxide-rich absorbing liquid in the carbon dioxide-rich absorbing liquid storage tank installed in the first-class factory 1 to the carbon dioxide-rich absorbing liquid storage tank installed in the third-class factory 3.

[0152] The carbon dioxide transport means (1) 17 is a means for transporting the carbon dioxide recovered in the third type factory 3 to the carbon dioxide consuming factory.

[0153] The carbon dioxide transport means (1) 17 is not particularly limited as long as it is capable of transporting carbon dioxide from the third-class factory 3 to the carbon dioxide consuming factory, and examples thereof include a pipeline connecting the carbon dioxide discharge pipe of the absorption and regeneration tower of the third-class factory 3 or the carbon dioxide storage tank installed in the third-class factory 3 to the carbon dioxide receiving tank of the carbon dioxide consuming factory or a reaction apparatus for a reaction using carbon dioxide as a raw material, a tanker truck, a freight tank car, or other mobile object.

[0154] Carbon dioxide-consuming factories use carbon dioxide as a raw material to produce various chemical products, minerals, artificial photosynthesis, plant factories, carbon capture and storage (CCS), bioenergy carbon capture and storage (BECCS), etc. For example, carbon dioxide-consuming factories produce oxo (CO / H) synthesis gas, engine materials such as methanol and dimethyl ether (DME), polycarbonate, urethane, biomass-derived chemicals, commodity chemicals such as ethylene / propylene / butene (olefins) and benzene / toluene / xylene (BTX), fuels such as biojet fuel from microalgae, biodiesel fuel, methane fuel, and bioalcohol fuel, and minerals such as concrete structures, paving materials, and carbonates.

[0155] Server 4 has a receiving unit and a calculation unit, and is connected to the computers installed in Type 1 factory 1, Type 3 factory 3, and Carbon Dioxide Consumption Factory 5 via a computer network based on high-speed communication lines and an LWPA communication system. In Figure 6, the connections via the computer network based on high-speed communication lines and an LWPA communication system are shown with dotted lines. Examples of computer networks based on high-speed communication lines and an LWPA communication system include computer networks using optical fiber, LAN, wireless, and dedicated lines.

[0158] The management data transmitted from the third-class factory 3 to the receiving unit of the server 4 is data necessary for the calculation unit of the server 4 to calculate the amount of carbon dioxide lean absorption liquid transported from the third-class factory 3 to the first-class factory 1, the target production amount of carbon dioxide-rich absorption liquid in the absorption process (2) at the third-class factory 3, and the target production amounts of carbon dioxide lean absorption liquid and carbon dioxide in the regeneration process (2), and is, for example, the flow rate of the carbon dioxide-rich absorption liquid produced in the absorption and regeneration tower at the third-class factory 3, the storage amount of the carbon dioxide-rich absorption liquid, the carbon dioxide content in the carbon dioxide lean absorption liquid, the production amount of the carbon dioxide lean absorption liquid and the storage amount of the carbon dioxide lean absorption liquid, the number of carbon dioxide-rich absorption liquid transport means or carbon dioxide lean absorption liquid transport means dispatched or the number of dispatched ships, etc.

[0159] The data on the required amount of carbon dioxide transmitted from the carbon dioxide consuming factory 5 is a predicted value of the demand for carbon dioxide calculated based on the carbon dioxide demand forecast at the carbon dioxide consuming factory 5. This predicted value of the demand for carbon dioxide is calculated by the server 4 based on production forecasts or past performance data for periods such as a year, month, or week.

[0160] The calculation unit of the server 4 compares the management data sent from the first factory 1 and received by the receiving unit, the management data (actual measured value) sent from the third factory 3 and received by the receiving unit, the data (predicted value) on the required amount of carbon dioxide sent from the carbon dioxide consuming factory 5 and received by the receiving unit, and the mobile unit position information sent from the transportation means, and calculates the amount of carbon dioxide-rich absorbing liquid to be transported from the first factory 1 to the third factory 3, the amount of carbon dioxide-lean absorbing liquid to be transported from the third factory 3 to the first factory 1, the target amount of carbon dioxide-rich absorbing liquid to be produced in the absorption step (2) at the third factory 3, and the target amounts of carbon dioxide-lean absorbing liquid and carbon dioxide to be produced in the regeneration step (2), and sends the data on the amount of carbon dioxide-rich absorbing liquid to the computer of the first factory 1, and sends the data on the amount of carbon dioxide-lean absorbing liquid to be transported, the target amount of carbon dioxide-rich absorbing liquid to be produced in the absorption step (2), and the target amounts of carbon dioxide-lean absorbing liquid and carbon dioxide to be produced in the regeneration step (2), to the computer of the third factory 3.

[0161] Then, based on the data on the transport amount of the carbon dioxide-rich absorbing solution transmitted from the server 4, the carbon dioxide-rich absorbing solution is transported from the first type factory 1 to the third type factory 3. Also, based on the transport amount data of the carbon dioxide-lean absorbing solution transmitted from the server 4, the carbon dioxide-lean absorbing solution is transported from the third type factory 3 to the first type factory 1. Also, at the third type factory 3, based on the data on the target production amount of the carbon dioxide-rich absorbing solution in the absorption step (2) and the target production amounts of the carbon dioxide-lean absorbing solution and carbon dioxide in the regeneration step (2) transmitted from the server 4, the absorption step (2) and the regeneration step (2) are performed so as to achieve the target production amounts.

[0162] In the carbon dioxide recovery management system for a gaseous carbon dioxide supply source of the present invention (4), both the carbon dioxide lean absorption liquid and the carbon dioxide rich absorption liquid are absorption liquids containing an absorbent. The carbon dioxide lean absorption liquid is an absorption liquid from which carbon dioxide has been desorbed in the regeneration step and from which the amount of carbon dioxide absorbed is small. On the other hand, the carbon dioxide rich absorption liquid is an absorption liquid from which carbon dioxide has been absorbed in the absorption step and from which the amount of carbon dioxide absorbed is large.

[0163] The absorbing liquid is not particularly limited as long as it can absorb carbon dioxide from a gaseous carbon dioxide supply source at 90 to 300 kPa, preferably 90 to 130 kPa.

[0164] Examples of absorbents contained in the absorbing solution include all amine compounds, such as alkanolamines such as monoethanolamine, diethanolamine, diisopropanolamine, dimethyldiethanolamine, and triethanolamine, amino alcohols such as aminodiethylene glycol, hindered amine compounds, piperazine compounds, piperidine compounds, polyalkylpolyamine compounds, amino acid compounds, amino acid salt compounds, and derivatives thereof, as well as organic amine compounds. The absorbent may be one type or a combination of two or more of the above types in any mixing ratio. Preferred absorbents have a high absorption rate, a large carbon dioxide absorption capacity, are thermally stable, and require little energy for regeneration.

[0165] The carbon dioxide cyclic loading amount of the absorbent contained in the absorption liquid is preferably 0.85 mol (CO2) / L (solution) or more, particularly preferably 2.0 to 7.0 mol (CO2) / L (solution). When the carbon dioxide cyclic loading amount of the absorbent is within the above range, the amount of circulation of the absorption liquid is reduced, and the required area for installing the equipment can be reduced. In the present invention, the carbon dioxide cyclic loading amount of the absorbent is calculated by the following formula. Carbon dioxide cyclic loading of absorbent (moles (CO2) / L (solution)) = carbon dioxide absorption at 40°C and 20 kPa (moles (CO2) / L (solution)) - carbon dioxide absorption at 120°C and 100 kPa (moles (CO2) / L (solution))

[0166] The carbon dioxide absorption rate of the absorbent contained in the absorbing solution is preferably 0.09 mol (CO2) / L (solution) per minute or more, particularly preferably 0.10 to 0.20 mol (CO2) / L (solution) per minute. When the carbon dioxide absorption rate of the absorbent is within the above range, reactive absorption of carbon dioxide in the absorption step is promoted, and the height of the absorption and regeneration tower can be reduced.

[0167] The carbon dioxide desorption energy of the absorbent contained in the absorbing solution is preferably 90 kJ / mol (CO2) or less, particularly preferably 30 to 75 kJ / mol (CO2). When the carbon dioxide desorption energy of the absorbent is within the above range, carbon dioxide desorption in the regeneration step occurs more easily, and the required energy can be kept low.

[0168] The absorbing liquid is, for example, an aqueous solution of an absorbent. The absorbing liquid is preferably an aqueous solution of alkanolamine, and particularly preferably an aqueous solution of alkanolamine with a concentration of 15 to 45% by mass.

[0169] In the system for recovering and managing carbon dioxide in a gaseous carbon dioxide supply source of the present invention (4), the location of the server 4 is not particularly limited, and may be in Japan or outside Japan.

[0170] The gaseous carbon dioxide supply source for the absorption step is a gas containing carbon dioxide. Examples of the gaseous carbon dioxide supply source include exhaust gases emitted from equipment such as blast furnaces, lime kilns, heating furnaces, reactors, and boilers in power plants, steel mills, cement plants, oil refineries, and chemical plants. Another example of the gaseous carbon dioxide supply source is the atmosphere.

[0171] The carbon dioxide concentration in the gaseous carbon dioxide supply source for the absorption step is 50.0% by volume or less, preferably 2.0 to 25.0% by volume, and particularly preferably 2.0 to 20.0% by volume. The pressure of the gaseous carbon dioxide supply source supplied to the absorption and regeneration tower is 90 to 300 kPa, and preferably 90 to 130 kPa.

[0240] In the embodiment shown in Figures 6 to 10, the number of type 1 factories is three, but the carbon dioxide recovery and management system in the gaseous carbon dioxide supply source of the present invention (4) is not limited to this, and the number of type 1 factories may be one or more. Also, in the embodiment shown in Figures 6 to 10, the number of type 3 factories is one, but the carbon dioxide recovery and management system in the gaseous carbon dioxide supply source of the present invention (4) is not limited to this, and the number of type 3 factories may be one or more. Also, in the embodiment shown in Figures 6 to 10, the number of carbon dioxide consuming factories is one, but the carbon dioxide recovery and management system in the gaseous carbon dioxide supply source of the present invention (4) is not limited to this, and the number of carbon dioxide consuming factories may be one or more. Also, in the embodiment shown in Figures 7 and 10, the number of type 2 factories is one, but the carbon dioxide recovery and management system in the gaseous carbon dioxide supply source of the present invention (4) is not limited to this, and the number of type 2 factories may be one or more. In addition, in the embodiments shown in Figures 8, 9 and 10, the number of fourth-class factories is one, but the carbon dioxide recovery management system in the gaseous carbon dioxide supply source of the present invention (4) is not limited to this, and the number of fourth-class factories may be one or more.

[0241] In the carbon dioxide recovery management system for a gaseous carbon dioxide supply source of the present invention (4), the server can further calculate a target production amount of the carbon dioxide-rich absorption liquid at the first-class factory and transmit data on the target production amount of the carbon dioxide-rich absorption liquid to the first-class factory.

[0242] In the carbon dioxide recovery system in the gaseous carbon dioxide supply source of the present invention (4), the server can further compare the data with the operation plan of each factory and transmit corrected operation management data to each factory based on the analysis results of the supply and demand balance.

[0243] In the present invention, the target production amount refers to the quantities of carbon dioxide-rich absorption solution, carbon dioxide-lean absorption solution, and carbon dioxide required to maintain the balance between supply and demand of carbon dioxide in the carbon dioxide recovery management system in the gaseous carbon dioxide supply source of the present invention (4).

[0244] In the carbon dioxide recovery management system for a gaseous carbon dioxide supply source of the present invention (4), the timing of transmitting data such as the amount of carbon dioxide-rich absorbing solution to be transported, the carbon dioxide-rich absorbing solution, the carbon dioxide-lean absorbing solution, and the target amount of carbon dioxide produced from the server to each factory is not particularly limited, and examples thereof include sequentially, at a fixed time such as once a day, or when requested by each factory.

[0245] In the carbon dioxide recovery management system in the gaseous carbon dioxide supply source of the present invention (4), the timing of transmission of each management data from the computer of each factory to the server is not particularly limited, and examples include sequentially, at a fixed time such as once a day, or when requested by each factory.

[0246] In the carbon dioxide recovery system in the gaseous carbon dioxide supply source of the present invention (4), the amount of carbon dioxide produced in the regeneration step (2) in the third factory is adjusted so that carbon dioxide is produced according to the required amount of carbon dioxide based on the carbon dioxide demand forecast at the carbon dioxide consuming factory, and the amount of carbon dioxide-rich absorbing liquid produced in the absorption step (1) in the first factory is adjusted so that the amount of carbon dioxide-rich absorbing liquid required to perform the regeneration step (2) is produced, and the amount of carbon dioxide-rich absorbing liquid transported from the first factory to the third factory and the amount of carbon dioxide-lean absorbing liquid transported from the third factory to the first factory can be adjusted so that the amounts of carbon dioxide-rich absorbing liquid and carbon dioxide-lean absorbing liquid required to perform these steps are present at the first factory and the third factory, so that the amounts of carbon dioxide recovered from each of the first and third factory according to the carbon dioxide demand can be managed comprehensively.

[0247] Furthermore, since the operating conditions and operating schedules of the combustion equipment differ for each factory that captures carbon dioxide, the amount of carbon dioxide-rich absorbing solution produced at each factory is constantly fluctuating. Therefore, if the amount of carbon dioxide-rich absorbing solution delivered to each factory, the carbon dioxide-rich absorbing solution, the carbon dioxide-lean absorbing solution, and the target carbon dioxide production amount, etc., were always the same, comprehensive management would not be possible. In the carbon dioxide capture system for a gaseous carbon dioxide supply source of the present invention (4), the amount of carbon dioxide-rich absorbing solution delivered to each factory, the carbon dioxide-rich absorbing solution, the carbon dioxide-lean absorbing solution, and the target carbon dioxide production amount, etc., can be calculated for each factory at any given time, taking into account the operating conditions and operating schedules of the combustion equipment at each factory, thereby enabling comprehensive management of the carbon dioxide capture method.

[0250] In FIG. 11, the carbon dioxide recovery management system 10k in a gaseous carbon dioxide supply source has at least a first-class factory 1, a fourth-class factory 6, a server 4, a carbon dioxide-rich absorption liquid transport means (1) 11, a carbon dioxide-lean absorption liquid transport means (1) 14, and a carbon dioxide transport means (1) 13.

[0251] The first-class factory 1 is equipped with an absorption tower, a carbon dioxide-lean absorbing liquid storage tank, and a carbon dioxide-rich absorbing liquid storage tank. In the absorption tower, the first-class factory 1 performs an absorption step (1) in which carbon dioxide in a gaseous carbon dioxide supply source containing carbon dioxide is reactively absorbed by the carbon dioxide-lean absorbing liquid, and the resulting carbon dioxide-rich absorbing liquid is sent to and stored in the carbon dioxide-rich absorbing liquid storage tank. The absorption step (1) is a step in which the gaseous carbon dioxide supply source discharged from a combustion device or the like in the first-class factory 1 is supplied to the absorption tower, and the carbon dioxide-lean absorbing liquid is supplied from the carbon dioxide-lean absorbing liquid storage tank installed in the first-class factory 1. The gaseous carbon dioxide supply source and the carbon dioxide-lean absorbing liquid come into contact with each other in the absorption tower, causing the carbon dioxide in the gaseous carbon dioxide supply source to react with an absorbent, such as an amine compound, contained in the carbon dioxide-lean absorbing liquid and be reactively absorbed by the carbon dioxide-lean absorbing liquid to produce a carbon dioxide-rich absorbing liquid. The carbon dioxide-rich absorbing liquid produced by the reactive absorption is then sent to the carbon dioxide-rich absorbing liquid storage tank and stored.

[0252] The absorption tower, carbon dioxide lean absorption liquid storage tank, and carbon dioxide rich absorption liquid storage tank installed in the first-class factory 1 are not particularly limited, and are appropriately selected depending on the supply amount of the gaseous carbon dioxide supply source, the pressure or carbon dioxide concentration, the supply amount of the carbon dioxide lean absorption liquid, the type of absorbent contained in the absorption liquid, the production amount of the carbon dioxide rich absorption liquid, the retained amount of the carbon dioxide lean absorption liquid, the retained amount of the carbon dioxide rich absorption liquid, etc.

[0253] The fourth-class factory 6 is equipped with an absorption tower, a regeneration tower, a carbon dioxide-lean absorption liquid storage tank, and a carbon dioxide-rich absorption liquid storage tank. The fourth-class factory 6 performs an "absorption step (3) in which, in the absorption tower, carbon dioxide in a gaseous carbon dioxide supply source containing carbon dioxide is reactively absorbed by the carbon dioxide-lean absorption liquid, and the carbon dioxide-rich absorption liquid produced is sent to the regeneration tower," and a "regeneration step (3) in which, in the regeneration tower, the carbon dioxide-rich absorption liquid is heated to desorb carbon dioxide from the carbon dioxide-rich absorption liquid, and the carbon dioxide-lean absorption liquid is regenerated, and then the desorbed carbon dioxide is recovered, and the carbon dioxide-lean absorption liquid is sent to the absorption tower."

[0254] The absorption step (3) is a step in which the absorption tower is supplied with a gaseous carbon dioxide supply source discharged from a device installed in the fourth-type factory 6, and a carbon dioxide-lean absorption liquid is supplied from a regeneration tower installed in the fourth-type factory 6, and the gaseous carbon dioxide supply source and the carbon dioxide-lean absorption liquid come into contact with each other in the absorption tower, causing the carbon dioxide in the gaseous carbon dioxide supply source to react with the absorbent contained in the carbon dioxide-lean absorption liquid and be reactively absorbed by the carbon dioxide-lean absorption liquid to produce a carbon dioxide-rich absorption liquid, and then the carbon dioxide-rich absorption liquid produced by the reactive absorption is sent to the regeneration tower.

[0255] The regeneration step (3) is a step in which a carbon dioxide-rich absorbing solution is supplied to the regeneration tower from an absorption tower installed in the fourth-class factory 6, and the carbon dioxide-rich absorbing solution is heated in the regeneration tower to desorb carbon dioxide from the carbon dioxide-rich absorbing solution, thereby regenerating a carbon dioxide-lean absorbing solution, and then the desorbed carbon dioxide is recovered, and the carbon dioxide-lean absorbing solution produced by the desorption of carbon dioxide is sent to the absorption tower.

[0256] In the fourth-type factory 6, the absorption process (3) and the regeneration process (3) are carried out simultaneously.

[0257] The absorption tower and regeneration tower, carbon dioxide lean absorption liquid storage tank and carbon dioxide rich absorption liquid storage tank installed in the fourth type factory 6 are not particularly limited, and are appropriately selected depending on the supply amount of the gaseous carbon dioxide supply source, the pressure or carbon dioxide concentration, the amount of carbon dioxide produced, the type of absorbent contained in the absorption liquid, the amount of carbon dioxide lean absorption liquid produced, the amount of carbon dioxide lean absorption liquid held, the amount of carbon dioxide rich absorption liquid held, etc.

[0258] The carbon dioxide-rich absorbing liquid transport means (1) 11 is a means for transporting the carbon dioxide-rich absorbing liquid in the carbon dioxide-rich absorbing liquid storage tank installed in the first-class factory 1 to the carbon dioxide-rich absorbing liquid storage tank installed in the fourth-class factory 6.

[0259] The carbon dioxide-rich absorbing liquid transport means (1) 11 is not particularly limited as long as it is capable of transporting the carbon dioxide-rich absorbing liquid from the first-class factory 1 to the fourth-class factory 6, and examples thereof include mobile bodies such as tank trucks, ships, and tank cars, and pipelines connecting the carbon dioxide-rich absorbing liquid storage tank of the first-class factory 1 and the carbon dioxide-rich absorbing liquid storage tank of the fourth-class factory 6.

[0260] The carbon dioxide lean absorption liquid transport means (1) 14 is a means for transporting the carbon dioxide lean absorption liquid in the carbon dioxide lean absorption liquid storage tank installed in the fourth type factory 6 to the carbon dioxide lean absorption liquid storage tank installed in the first type factory 1.

[0262] The carbon dioxide transport means (1) 13 is a means for transporting the carbon dioxide recovered in the fourth type factory 6 to the carbon dioxide consuming factory.

[0263] The carbon dioxide transport means (1) 13 is not particularly limited as long as it is capable of transporting carbon dioxide from the fourth-class factory 6 to the carbon dioxide consuming factory, and examples thereof include a pipeline connecting the carbon dioxide discharge pipe of the regeneration tower of the fourth-class factory 6 or the carbon dioxide storage tank installed in the fourth-class factory 6 to the carbon dioxide receiving tank of the carbon dioxide consuming factory or a reaction apparatus for a reaction using carbon dioxide as a raw material, a tanker truck, a freight tank car, or other mobile object.

[0264] Carbon dioxide-consuming factories use carbon dioxide as a raw material to produce various chemical products, minerals, artificial photosynthesis, plant factories, carbon capture and storage (CCS), bioenergy carbon capture and storage (BECCS), etc. For example, carbon dioxide-consuming factories produce oxo (CO / H) synthesis gas, engine materials such as methanol and dimethyl ether (DME), polycarbonate, urethane, biomass-derived chemicals, commodity chemicals such as ethylene / propylene / butene (olefins) and benzene / toluene / xylene (BTX), fuels such as biojet fuel from microalgae, biodiesel fuel, methane fuel, and bioalcohol fuel, and minerals such as concrete structures, paving materials, and carbonates.

[0265] Server 4 has a receiving unit and a calculation unit, and is connected to the computers installed in Type 1 factory 1, Type 4 factory 6, and Carbon Dioxide Consumption Factory 5 via a computer network based on high-speed communication lines and an LWPA communication system. In Figure 11, the connections via the computer network based on high-speed communication lines and an LWPA communication system are shown with dotted lines. Examples of computer networks based on high-speed communication lines and an LWPA communication system include computer networks using optical fiber, LAN, wireless, and dedicated lines.

[0266] The receiving section of the server 4 receives management data transmitted from the computer installed in the first-class factory 1, management data transmitted from the computer installed in the fourth-class factory 6, data on the required amount of carbon dioxide transmitted from the carbon dioxide consuming factory 5, and mobile object location information transmitted from the transportation means.

[0267] The management data transmitted from the first-class factory 1 to the receiving unit of the server 4 is data necessary for the calculation unit of the server 4 to calculate the amount of carbon dioxide-rich absorbing liquid to be transported from the first-class factory 1 to the fourth-class factory 6, the target production amount of carbon dioxide-rich absorbing liquid in the absorption step (3) at the fourth-class factory 6, and the target production amounts of carbon dioxide-lean absorbing liquid and carbon dioxide in the regeneration step (3), and is, for example, the flow rate of the carbon dioxide-rich absorbing liquid produced in the absorption tower at the first class factory, the storage amount of the carbon dioxide-rich absorbing liquid, the carbon dioxide content of the carbon dioxide-rich absorbing liquid, the storage amount of the carbon dioxide-lean absorbing liquid, the operation schedule of the combustion device at the first class factory 1, the number of vehicles or ships to be dispatched for the carbon dioxide-rich absorbing liquid transport means or the carbon dioxide-lean absorbing liquid transport means, etc.

[0268] The management data transmitted from the fourth-class factory 6 to the receiving unit of the server 4 is data necessary for the calculation unit of the server 4 to calculate the amount of carbon dioxide lean absorption liquid transported from the fourth-class factory 6 to the first-class factory 1, the target production amount of carbon dioxide rich absorption liquid in the absorption process (3) at the fourth-class factory 6, and the target production amounts of carbon dioxide lean absorption liquid and carbon dioxide in the regeneration process (3), and is, for example, the amount of carbon dioxide recovered at the fourth-class factory 6 and transported to the carbon dioxide consuming factory 5, the flow rate of the carbon dioxide lean absorption liquid produced in the regeneration tower, the storage amount of carbon dioxide rich absorption liquid, the storage amount of carbon dioxide lean absorption liquid, the number of vehicles or ships deployed for carbon dioxide rich absorption liquid transport means or carbon dioxide lean absorption liquid transport means, etc.

[0269] The data on the required amount of carbon dioxide transmitted from the carbon dioxide consuming factory 5 is a predicted value of the demand for carbon dioxide calculated based on the carbon dioxide demand forecast at the carbon dioxide consuming factory 5. This predicted value of the demand for carbon dioxide is calculated by the server 4 based on production forecasts or past performance data for periods such as a year, month, or week.

[0270] The calculation unit of the server 4 compares the management data sent from the first type factory 1 and received by the receiving unit, the management data (actual measured value) sent from the fourth type factory 6 and received by the receiving unit, the data (predicted value) on the required amount of carbon dioxide sent from the carbon dioxide consuming factory 5 and received by the receiving unit, and the mobile unit position information sent from the transportation means, and calculates the amount of carbon dioxide-rich absorbing liquid to be transported from the first type factory 1 to the fourth type factory 6, the amount of carbon dioxide-lean absorbing liquid to be transported from the fourth type factory 6 to the first type factory 1, the target amount of carbon dioxide-rich absorbing liquid to be produced in the absorption step (3) at the fourth type factory 6, and the target amount of carbon dioxide-lean absorbing liquid and carbon dioxide to be produced in the regeneration step (3), and transmits the data on the amount of carbon dioxide-rich absorbing liquid to the computer of the first type factory 1, and transmits the data on the amount of carbon dioxide-lean absorbing liquid to be transported, the target amount of carbon dioxide-rich absorbing liquid to be produced in the absorption step (3), and the target amount of carbon dioxide-lean absorbing liquid and carbon dioxide to be produced in the regeneration step (3), to the computer of the fourth type factory 6.

[0271] Then, based on the data on the transport amount of the carbon dioxide-rich absorbing solution transmitted from the server 4, the carbon dioxide-rich absorbing solution is transported from the first type factory 1 to the fourth type factory 6. Also, based on the transport amount data of the carbon dioxide-lean absorbing solution transmitted from the server 4, the carbon dioxide-lean absorbing solution is transported from the fourth type factory 6 to the first type factory 1. Also, at the fourth type factory 6, based on the data on the target production amount of the carbon dioxide-rich absorbing solution in the absorption step (3) and the target production amounts of the carbon dioxide-lean absorbing solution and carbon dioxide in the regeneration step (3) transmitted from the server 4, the absorption step (3) and the regeneration step (3) are performed so as to achieve the target production amounts.

[0272] In the carbon dioxide recovery management system for a gaseous carbon dioxide supply source of the present invention, both the carbon dioxide-lean absorbing liquid and the carbon dioxide-rich absorbing liquid are absorbing liquids containing an absorbent. The carbon dioxide-lean absorbing liquid is an absorbing liquid from which carbon dioxide has been desorbed in the regeneration step and from which the amount of carbon dioxide absorbed is small. On the other hand, the carbon dioxide-rich absorbing liquid is an absorbing liquid from which carbon dioxide has been absorbed in the absorption step and from which the amount of carbon dioxide absorbed is large.

[0273] The absorbing liquid is not particularly limited as long as it can absorb carbon dioxide from a gaseous carbon dioxide supply source at 90 to 300 kPa, preferably 90 to 130 kPa.

[0274] Examples of absorbents contained in the absorbing solution include all amine compounds, such as alkanolamines such as monoethanolamine, diethanolamine, diisopropanolamine, dimethyldiethanolamine, and triethanolamine, amino alcohols such as aminodiethylene glycol, hindered amine compounds, piperazine compounds, piperidine compounds, polyalkylpolyamine compounds, amino acid compounds, amino acid salt compounds, and derivatives thereof, as well as organic amine compounds. The absorbent may be one type or a combination of two or more of the above types in any mixing ratio. Preferred absorbents have a high absorption rate, a large carbon dioxide absorption capacity, are thermally stable, and require little energy for regeneration.

[0275] The carbon dioxide cyclic loading amount of the absorbent contained in the absorption liquid is preferably 0.85 mol (CO2) / L (solution) or more, particularly preferably 2.0 to 7.0 mol (CO2) / L (solution). When the carbon dioxide cyclic loading amount of the absorbent is within the above range, the amount of circulation of the absorption liquid is reduced, and the required area for installing the equipment can be reduced. In the present invention, the carbon dioxide cyclic loading amount of the absorbent is calculated by the following formula. Carbon dioxide cyclic loading of absorbent (moles (CO2) / L (solution)) = carbon dioxide absorption at 40°C and 20 kPa (moles (CO2) / L (solution)) - carbon dioxide absorption at 120°C and 100 kPa (moles (CO2) / L (solution))

[0276] The carbon dioxide absorption rate of the absorbent contained in the absorbing solution is preferably 0.09 mol (CO2) / L (solution) per minute or more, particularly preferably 0.10 to 0.20 mol (CO2) / L (solution) per minute. When the carbon dioxide absorption rate of the absorbent is within the above range, reactive absorption of carbon dioxide in the absorption step is promoted, and the height of the absorption and regeneration tower can be reduced.

[0277] The carbon dioxide desorption energy of the absorbent contained in the absorbing solution is preferably 90 kJ / mol (CO2) or less, particularly preferably 30 to 75 kJ / mol (CO2). When the carbon dioxide desorption energy of the absorbent is within the above range, carbon dioxide desorption in the regeneration step occurs more easily, and the required energy can be kept low.

[0278] The absorbing liquid is, for example, an aqueous solution of an absorbent. The absorbing liquid is preferably an aqueous solution of alkanolamine, and particularly preferably an aqueous solution of alkanolamine with a concentration of 15 to 45 mass %.

[0279] In the system for recovering and managing carbon dioxide in a gaseous carbon dioxide supply source of the present invention (7), the location of the server 4 is not particularly limited, and may be in Japan or outside Japan.

[0280] The gaseous carbon dioxide supply source for the absorption step is a gas containing carbon dioxide. Examples of the gaseous carbon dioxide supply source include exhaust gases emitted from equipment such as blast furnaces, lime kilns, heating furnaces, reactors, and boilers in power plants, steel mills, cement plants, refineries, and chemical plants.

[0281] The carbon dioxide concentration in the gaseous carbon dioxide supply source for the absorption step is 50.0% by volume or less, preferably 2.0 to 25.0% by volume, and particularly preferably 2.0 to 20.0% by volume. The pressure of the gaseous carbon dioxide supply source supplied to the absorption and regeneration tower is 90 to 300 kPa, and preferably 90 to 130 kPa.
