Description

Technology Field

[0001] The present invention relates to a system and method for calculating and controlling greenhouse gas reductions by capturing and mineralizing carbon dioxide from exhaust gases of a boiler that is a building emission source. More specifically, the invention relates to a system and method for calculating and controlling greenhouse gas reductions that precisely calculates and controls, in real time, a net reduction based on a life cycle assessment (LCA) of the entire process of mineralizing captured carbon dioxide and permanently sequestering plastics, while maintaining active pressure control and a safe capture mechanism to prevent the risk of exhaust backflow from boiler exhaust facilities within the building, based on heatless circulation absorption conditions within the process. Background Technology

[0002] Greenhouse gases emitted from various human economic activities since the 20th century are considered the primary cause of global climate change. Under the transparency framework emphasized in the new climate regime initiated by the Paris Agreement, accurate measurement of greenhouse gases serves as important scientific evidence for estimating the direct impact of greenhouse gases on climate change and for inferring changes in carbon emissions and burnup.

[0003] Fossil fuels, the world's major energy source, took hundreds of millions of years to form, but their consumption has increased too rapidly since the Industrial Revolution to improve operational efficiency in industrial processes. It is predicted that if fossil fuels continue to be consumed at the current rate, most of the fossil fuels on Earth will be depleted around 2060.

[0004] In addition to the problem of depletion, fossil fuels such as coal, oil, and natural gas emit large amounts of CO₂ when burned, which has an adverse effect on the environment. Generally, the six major greenhouse gases (GHGs) include carbon dioxide (CO₂), methane (CH₄), sulfur fluoride (SF₆), chlorofluorocarbons (CFCs), perfluorocarbons (PFCs), and nitrous oxide (N₂O), but considering the emissions, global warming and climate change are considered to be primarily caused by CO₂.

[0005] Accurately measuring, identifying, capturing, and utilizing CO₂ emissions and burnup, which account for 80% of global greenhouse gas radiative forcing, is essential to prevent a 2°C rise in global temperature, and the development and improvement of Carbon Capture, Utilization, and Storage are necessary for establishing effective climate change response policies.

[0006] The carbon dioxide capture process is divided into pre-combustion capture, post-combustion capture, and oxygen-fuel combustion capture.

[0007] Pre-combustion capture is a method of capturing carbon dioxide by converting it into a mixture of hydrogen and carbon dioxide through pretreatments such as partial oxidation of fossil fuels, natural gas reforming, and water-gas shift reactions.

[0008] Post-Combustion Capture utilizes a chemical solvent to capture carbon dioxide generated after combustion from exhaust gases emitted during the combustion process; the captured carbon dioxide is subsequently separated from the solvent and compressed for transport and storage.

[0009] Oxy-Fuel Combustion Capture requires a process to separate oxygen from air. By burning coal and gas with the separated oxygen instead of air, a concentrated, high-concentration carbon dioxide scum is produced, which allows for easier separation of carbon dioxide and subsequent capture.

[0010] Among these, the wet capture method, a post-combustion capture method, is widely adopted for utility through CO₂ mineralization conversion.

[0011] In measuring carbon emissions, conventional methods calculate a baseline based on the total consumption of fossil fuels; however, when capturing the entire exhaust outlet of building-type facilities, it was impossible to ensure facility safety due to factors such as exhaust gas backflow.

[0012] Furthermore, there is currently a lack of reliable algorithms capable of correcting the gap between high-efficiency data from the laboratory and actual field conditions where low-concentration exhaust gases are emitted.

[0014] The matters described as background technology above are intended only to enhance understanding of the background of the present invention and should not be construed as an acknowledgment that they constitute prior art already known to those skilled in the art. Prior art literature

[0015] Patent Document 1 : KR 10-2913554 B1 (2026.01.13.) “Electrical Equipment Carbon Emission Calculator” The problem to be solved

[0016] The main problem that the present invention aims to solve is to provide a building-type carbon dioxide capture control system capable of ensuring facility stability by fundamentally blocking the risk of backflow of exhaust gases generated when operating emission facilities, such as boilers, within urban buildings, and a method for calculating greenhouse gas reduction amounts using the same.

[0017] In addition, the present invention aims to ensure the objective reliability of reduction amount data by correcting the data gap between laboratory-based high-concentration reference data and the operating conditions of actual building sites where low-concentration exhaust gases are emitted in real time through a multifaceted weighting algorithm based on flow velocity, pipe cross-sectional area, and concentration ratio.

[0018] In addition, we aim to provide a verification mechanism that can prevent the possibility of gaseous re-release and leakage of carbon (realizing a leakage amount of '0') by utilizing the physicochemical partial pressure equilibrium characteristics within a sealed container during the process of temporarily storing and transporting carbon dioxide absorbed on-site in a super-captured liquid (solution) state without immediately converting it into a solid state to an external resource recycling plant.

[0019] Finally, the present invention aims to provide a highly reliable integrated net greenhouse gas reduction calculation platform that precisely controls subtraction by linking the equipment power consumption (Scope 2) and the transport emissions of electric trucks (Scope 3) according to the distance traveled by the solution and product, based on a life cycle assessment (LCA) from the capture stage at the building site to the final calcium carbonate (CaCO₃) immobilization and productization stage at an external factory.

[0024] A reduction amount determination unit (30) that determines the net greenhouse gas reduction amount by deducting in real time the emissions from the operation of the field capture facility (200) and the emissions from the transport of the solution to the external resource recycling plant (300) and the emissions from the transport of the solution and the transport of the final calcium carbonate (CaCO₃) product by electric truck travel distance;

[0025] A system for calculating and controlling greenhouse gas reductions for a building-type carbon dioxide capture and mineralization facility, comprising...

[0026] In the present invention, the dedicated amine-based absorbent comprises one alone or a complex mixture of two or more selected from the group consisting of monoethanolamine (MEA), diglycolamine (DGA), 2-amino-2-methyl-1-propanol (AMP), butylamine (BA), pentylamine (PEA), diethanolamine (DEA), diisopropanolamine (DIPA), monoisopropanolamine (MIPA), 2-(ethylamino)ethanol (EAE), 2-(butylamino)ethanol (BMA), N-methyldiethanolamine (MDEA), triethanolamine (TEA), 2-(diethylamino)ethanol (DEMEA), triethylamine (TREA), dimethylaminomethylpropanol (DMAM), piperazine (PZ), 1-(2-aminoethyl)piperazine (AEP), ethylenediamine (EDA), diethylenetriamine (DETA), and triethylenetetramine (TETA). The composition is a mixture of a main absorbent (hereinafter referred to as 'Lycel A' in the present invention) and an oxidation-inhibiting composite control agent (hereinafter referred to as 'Lycel B' in the present invention) composed of a combination of three or more selected from diethyl phosphate, dimethyl phosphate, tributyl phosphate, ethyl phosphonic acid, tripotassium phosphate, disodium phosphate, potassium pyrophosphate, calcium carbonate, potassium hydroxide, amino acid salts, etc., and the calculation control unit (20) can match the chelate blocking activity of transition metal ions in the absorbent solution and the oxidative degradation inhibition efficiency of amine molecules in real time according to the input concentration of the composite control agent (Lycel B), calculate the non-thermal continuous circulation usage cycle of the main absorbent (Lycel A) in the process without a separate thermal regeneration process, and control the transfer cycle.

[0027] In the present invention, the reference carbon capture amount (emission amount before capture) is not based on the theoretical emission amount according to the total fossil fuel usage of the building boiler, but can be calculated by back-calculating only the pure mass of CO₂ that is transferred to the external resource recycling plant (300) and finally converted and immobilized into calcium carbonate (CaCO₃) from the actual exhaust gas data introduced from a specific outlet while the risk of backflow is controlled through the ring blower inverter control of the data collection control unit (10).

[0028] In the present invention, the reduction amount determination unit (30) can verify the integrity of the seal by monitoring in real time whether carbon dioxide gas is re-emitted in the super-capture solution state stored in a sealed container (210) at the building site before transfer to an external resource recycling plant (300). At this time, the mechanism is based on the partial pressure equilibrium of carbon dioxide (CO₂) achieved by the gas phase space inside the sealed container, and if it is confirmed through the monitoring that an equilibrium state without gas re-emission is maintained, the accuracy of calculating the net greenhouse gas reduction amount can be maximized by converging the variables of carbon leakage amount during the storage stage before transfer to the external resource recycling plant (300) and carbon leakage amount during transport under the same sealing conditions to '0'.

[0029] In the present invention, the reduction amount determination unit (30) can feed the calcium carbonate (CaCO₃) finally precipitated and recovered from the external resource recycling plant (300) as a filler to replace synthetic resin in the polymer plastic compounding process, thereby irreversibly and permanently sequestering it within the matrix of the final plastic molded product, and can control approval as greenhouse gas reduction credit (Carbon Credit) issuance data by calculating and correcting to satisfy the long-term carbon sequestration criteria of the accredited international greenhouse gas calculation standard guideline based on the internal life cycle of the plastic molded product.

[0030] At this time, the reduction amount determination unit (30) can perform calculation correction logic to satisfy the carbon sequestration and sustainability assessment criteria presented in at least one of the accredited international greenhouse gas calculation standards among ISO 14064-2 (project emission calculation standard), ISO 14067 (product carbon footprint calculation standard), GHG Protocol and IPCC (Intergovernmental Panel on Climate Change) guidelines, in order to ensure that carbon is stably sequestered during the product's life cycle and not re-emitted into the atmosphere.

[0031] The present invention provides a method for calculating and controlling greenhouse gas reduction amount, comprising the following steps using the greenhouse gas reduction amount calculation and control system (100) above.

[0032] In one embodiment, the present invention comprises the step of: (a) a data collection control unit (10) actively controlling a downstream ring blower inverter and a bypass valve according to real-time measurements of a pressure sensor and a flow rate sensor provided on the discharge side to prevent the risk of exhaust backflow of a boiler exhaust facility, thereby selectively introducing only a portion of the exhaust gas within a safe range into a collection facility, and measuring the piping area, flow rate, and carbon dioxide concentration of the introduced exhaust gas in real time;

[0033] (b) a step in which a calculation control unit (20) calculates a field correction weight defined as the product of the correlations of the flow rate ratio, cross-sectional area ratio, and carbon dioxide concentration ratio of laboratory-based reference process data and the field actual measurement data, and calculates the carbon capture saturation of a transport target solution in which carbon dioxide is overcaptured by a dedicated amine-based absorbent based on the weight, and dynamically estimates the transport cycle to an external resource recycling plant; and

[0034] (c) The reduction amount determination unit (30) determines that after the above-mentioned transfer target solution is transported to an external resource recycling plant, calcium ions (Ca 2+ A method for calculating and controlling greenhouse gas reduction is provided, characterized by comprising the step of: setting a reference carbon capture amount based on the measured weight of the final precipitated and recovered calcium carbonate (CaCO₃) solid through a reaction with ), and determining the final net greenhouse gas reduction amount by subtracting in real time project emissions, including emissions from equipment power consumption due to on-site equipment operation and transportation emissions by electric truck travel distance due to solution transfer to the external resource recycling plant and transportation of the final calcium carbonate product. Effects of the invention

[0035] The greenhouse gas reduction amount calculation and control system according to the present invention and the greenhouse gas reduction amount calculation method using the same have the following effects.

[0036] First, by applying an irreversible room-temperature solidification mechanism that is differentiated from existing high-temperature thermal shrinkage-based capture processes, the present invention can maximize carbon dioxide absorption efficiency while fundamentally solving the problem of reduced reversibility caused by oxidation and degradation of the capture solution.

[0037] Second, carbon dioxide (CO₂) generated from the combustion of fossil fuels can be captured with high efficiency to drastically reduce emissions into the atmosphere, and the captured CO₂ can be permanently sequestered and fixed into high-purity precipitated calcium carbonate (CaCO₃) of high industrial value.

[0038] Third, since the produced precipitated calcium carbonate can be utilized as a raw material for composite resins that can be immediately fed into plastic compounding and interior material injection molding processes through particle size control technology, there is an economic benefit in that it enables the establishment of a high-value-added resource circulation system while simultaneously securing carbon emission rights.

Terms defined in commonly used dictionaries should be interpreted as having meanings consistent with the context of the relevant technology and should not be interpreted as having an ideal or overly formal meaning unless explicitly defined in this invention.

[0045] The features of the present invention can be explained more clearly through the following examples.

[0047] Hereinafter, with reference to FIGS. 1 to 5, each configuration of the greenhouse gas reduction amount calculation and control system (100) according to one embodiment of the present invention will be described in more detail.

[0049] As shown in FIG. 1(A), the system (100) for calculating and controlling greenhouse gas reduction by capturing and mineralizing carbon dioxide from the exhaust gas of a building exhaust source boiler according to the present invention comprises: a data collection control unit (10) that receives real-time measurements from a pressure sensor (11) and a flow rate sensor (12) installed on one side of a specific exhaust port (111) of the boiler exhaust facility to prevent the risk of exhaust backflow of the boiler exhaust facility (110); and, when a safety threshold is exceeded or a sudden pressure fluctuation occurs, actively controls an inverter (14) and a bypass valve (15) that vary the frequency of a ring blower motor (13) provided at the rear end to adjust the gas suction pressure of the capture line, thereby selectively introducing only a portion of the total exhaust gas within a safe range into the capture facility (200), and measures the piping area, flow rate, and CO₂ concentration of the introduced exhaust gas in real time.

[0050] A calculation control unit (20) that compares laboratory-based standard process data with field measurement data from the data collection control unit (10) to calculate a weight defined as the correlation product of [flow rate ratio of field conditions to laboratory conditions], [cross-sectional area ratio], and [CO₂ concentration ratio], and calculates the carbon capture saturation of a transport target solution in which carbon dioxide is overcaptured by a dedicated amine-based absorbent based on the weight to dynamically estimate the transport cycle to an external resource recycling plant (300); and

[0051] The above-mentioned transport target solution is transported to an external resource recycling plant (300) and a reference carbon capture amount is set based on the mass of CO₂ in the final precipitated and recovered calcium carbonate (CaCO₃) solid through reaction with calcium ions (Ca²⁺), and the reduction amount determination unit (30) determines the net greenhouse gas reduction amount by subtracting in real time the emission from facility power consumption due to the operation of the field capture facility (200) and the transportation emission amount by electric truck travel distance due to the transport of the solution to the external resource recycling plant (300) and the transport of the final calcium carbonate product.

[0052] In one embodiment of the present invention, the dedicated amine-based absorbent comprises one alone or a complex mixture of two or more selected from the group consisting of monoethanolamine (MEA), diglycolamine (DGA), 2-amino-2-methyl-1-propanol (AMP), butylamine (BA), pentylamine (PEA), diethanolamine (DEA), diisopropanolamine (DIPA), monoisopropanolamine (MIPA), 2-(ethylamino)ethanol (EAE), 2-(butylamino)ethanol (BMA), N-methyldiethanolamine (MDEA), triethanolamine (TEA), 2-(diethylamino)ethanol (DEMEA), triethylamine (TREA), dimethylaminomethylpropanol (DMAM), piperazine (PZ), 1-(2-aminoethyl)piperazine (AEP), ethylenediamine (EDA), diethylenetriamine (DETA), and triethylenetetramine (TETA). The composition comprises a main absorbent (Lycel A) and an oxidation-inhibiting composite control agent (Lycel B) composed of a combination of three or more selected from diethyl phosphate, dimethyl phosphate, tributyl phosphate, ethyl phosphonic acid, tripotassium phosphate, disodium phosphate, potassium pyrophosphate, calcium carbonate, potassium hydroxide, amino acid salts, etc. At this time, the main absorbent (Lycel A) can immediately react with carbon dioxide (CO₂) in the incoming exhaust gas at room temperature without a heating process to form an intermediate in the form of a soluble carbon aqueous solution. The oxidation-inhibiting composite control agent (Lycel B) maintains the pH environment within the aqueous solution of the main absorbent (Lycel A) and preserves reaction activity, while simultaneously acting as an antioxidant and process stabilizer that inhibits irreversible oxidative degradation of amine molecules caused by oxygen (O₂) and metal impurities generated during the circulation and reuse of the absorbent solution.

[0053] In one embodiment of the present invention, the calculation control unit (20) can match the chelate blocking activity of transition metal ions in the absorbent solution and the oxidative degradation suppression efficiency of amine molecules in real time according to the input concentration of the composite control agent (Lycel B), calculate the non-thermal continuous circulation usage cycle of the main absorbent (Lycel A) in the process without a separate thermal regeneration process, and control the transfer cycle.

[0054] The reference carbon capture amount (emission amount before capture, baseline) of the present invention is not based on the theoretical emission amount according to the total fossil fuel usage of the building boiler, but can be calculated by back-calculating only the pure mass of CO₂ that is transferred to the external resource recycling plant (300) and finally converted and immobilized into calcium carbonate (CaCO₃) from the actual exhaust gas data introduced from a specific outlet while the risk of backflow is controlled through the ring blower inverter control of the data collection control unit (10).

[0055] This is intended to block errors caused by variable on-site factors, such as changes in combustion equipment efficiency or the influx of external air. By combining the ratio of carbon dioxide molecular weight to the total weight of finally dried calcium carbonate (CaCO₃), only the mass of carbon for which actual sequestration and immobilization have been achieved is filtered as valid data (Truth Data), allowing for real-time correction and verification of the reliability of the reference carbon capture amount (pre-capture emission, baseline).

[0056] In one embodiment of the present invention, the reduction amount determination unit (30) can verify the integrity of the seal by monitoring in real time whether carbon dioxide gas is re-emitted in the super-capture solution state stored in a sealed container at the building site before transfer to an external resource recycling plant (300). At this time, the mechanism is based on the partial pressure equilibrium of carbon dioxide (CO₂) achieved by the gas phase space inside the sealed container, and if it is confirmed through the monitoring that an equilibrium state without gas re-emission is maintained, the accuracy of calculating the net greenhouse gas reduction amount can be maximized by converging the variables of carbon leakage amount during the storage stage before transfer to the external resource recycling plant (300) and carbon leakage amount during transport under the same sealing conditions to '0'.

[0057] The present invention maximizes storage reliability and fundamentally prevents errors in leakage amount estimation by incorporating into the reduction amount estimation methodology a mechanism in which, even if a reversible self-decomposition reaction of solid carbonates occurs, a chemical equilibrium is reached and additional decomposition reactions cease automatically when the partial pressure of carbon dioxide in a sealed space reaches a certain level.

[0058] The final net reduction in greenhouse gases can be calculated using the following formula based on the data measured and inversely calculated by the system of the present invention.

[0059] [Calculation Formula]

[0060]

[0061] In the above formula, ER represents the annual final net greenhouse gas reduction (tCO₂eq / yr), and

[0062] BE represents a reference carbon capture amount (baseline emission amount, tCO₂eq / yr) determined by mutually cross-verifying the actual exhaust gas data (pipe area, flow rate) selectively introduced from a specific outlet (111) with the risk of backflow excluded through ring blower inverter control of the data collection control unit (10), the reference theoretical emission amount of incoming gas calculated by mathematically combining the LNG net calorific value coefficient and carbon emission coefficient of greenhouse gas regulations (Ministry of Environment and Korea Environment Corporation notification standards), and the sequestration mass back-calculated from the pure mass of CO₂ that is transferred to an external resource recycling plant (300) and converted into and immobilized as a final calcium carbonate (CaCO₃) solid.

[0063] PE represents the project greenhouse gas emissions (tCO₂eq / yr) calculated by summing the emissions (Scope 2) based on the total amount of electricity consumed in operating the above-mentioned capture facility (200) and external resource recycling plant (300), and the transport emissions (Scope 3) based on the distance traveled by electric trucks for the transfer of the solution to the above-mentioned external resource recycling plant (300) and the transport of the final calcium carbonate product.

[0064] LE represents the greenhouse gas leakage amount (Leakage, tCO₂eq / yr) that converges to '0' by blocking gas re-emission during the storage stage before transfer and the transport stage under the same sealed conditions through the control of the vapor-liquid equilibrium of carbon dioxide (CO₂) inside the sealed container (210).

[0066] In order to derive the 'reference carbon capture amount (BE)' which serves as the basis for establishing the greenhouse gas reduction amount calculation and control methodology of the present invention, actual exhaust gas data introduced from a specific outlet is collected while controlling the risk of backflow through the ring blower and inverter control of the data collection control unit (10). According to the methodology of the present invention, statistical theoretical emissions based on the total fossil fuel consumption of the hot water boiler are not used as a unilateral standard. Instead, based on the actual flow rate data of the incoming exhaust gas selectively introduced within a safe range by the data collection control unit (10), the 'LNG net calorific value coefficient' and 'carbon emission coefficient' of the Ministry of Environment and the Korea Environment Corporation are mathematically combined with the LNG consumption amount linked by reverse calculation to calculate the primary carbon mass at the inflow stage. Furthermore, the pure actual dry mass of CO₂, which is transferred to the external resource recycling plant (300) and finally converted and immobilized into calcium carbonate (CaCO₃), is back-calculated to calculate the secondary carbon mass.

[0067] The reduction amount determination unit (30) mutually matches and cross-checks the primary carbon mass (inflow reference theoretical value) and the secondary carbon mass (final fixed completed actual value), thereby finally determining and setting only valid data with secured reliability as the reference carbon capture amount (BE). This functions as an absolute reference indicator for subtracting the project emissions (PE), which include the power emissions (Scope 2) of the capture facility (200) and external factory and the transportation emissions (Scope 3) by electric truck travel distance, in the process of deriving the final net greenhouse gas reduction amount (ER), and the leakage amount (LE) variable is processed to converge to '0' due to the gas-liquid partial pressure equilibrium control of the sealed container (210).

[0069] In one embodiment of the present invention, the reduction amount determination unit (30) can feed the calcium carbonate (CaCO₃) finally precipitated and recovered from the external resource recycling plant (300) as a filler to replace synthetic resin in the polymer plastic compounding process, thereby irreversibly and permanently sequestering it within the matrix of the final plastic molded product, and control the approval of the greenhouse gas reduction credit (Carbon Credit) issuance data by calculating and correcting it to satisfy the long-term carbon sequestration criteria of the accredited international greenhouse gas calculation standard guideline based on the internal life cycle of the plastic molded product.

[0070] In one embodiment of the present invention, the reduction amount determination unit (30) can perform calculation correction logic to satisfy the carbon sequestration and sustainability assessment criteria presented in at least one of the accredited international greenhouse gas calculation standards among ISO 14064-2 (project emission calculation standard), ISO 14067 (product carbon footprint calculation standard), GHG Protocol and IPCC (Intergovernmental Panel on Climate Change) guidelines, in order to ensure that carbon is stably sequestered during the product's life cycle and not re-emitted into the atmosphere.

[0071] In the present invention, the external resource recycling plant (300) refers to an independent external production base that completes carbon sequestration and resource recovery by finally receiving the carbon dioxide supercapture transport target solution physically transported via a transport means such as an electric truck from the capture facility (200) and sealed container (210) at the building site. The external resource recycling plant (300) refers to a resource recovery facility that is spatially separated from the building emission source site, receives the carbon dioxide supercapture solution transported from the site sealed container (210), and is equipped with a complete device for finally precipitating and recovering calcium carbonate (CaCO₃) through a crystallization reaction with calcium ions (Ca2). Furthermore, the external resource recycling plant (300) functions as a valid data source category for actual measurement-based back-calculation that overcomes the theoretical emission limit of fossil fuels by measuring the actual dry mass and TIC (Total Inorganic Carbon) analysis data of the finally solidified calcium carbonate and transmitting them to the reduction amount determination unit (30).

[0072] In the present invention, the carbon reduction method involves fixing carbon dioxide emitted from an emission source (e.g., boiler, etc.) in a mineralized form and storing it in a location that minimizes exposure to external influences, such as an abandoned mine, and then considering the amount of leakage.

[0073] In the present invention, captured CO₂ is converted into a solid form of carbonate through a mineralization reaction. Here, calcium carbonate (CaCO₃) can be produced by combining the captured carbon dioxide with calcium.

[0074] The present invention enables the securing of a highly reliable long-term carbon sequestration period through storage and resource utilization processes following carbon capture. Currently, overseas IPCC (Intergovernmental Panel on Climate Change) guidelines and other standards for the storage period recognized in domestic and international CCS (Carbon Capture & Storage) and CCU (Carbon Capture & Utilization) reduction methodologies require carbon sequestration sustainability of at least 100 years.

[0075] In response to this, the present invention can achieve physical and chemically irreversible permanent fixation inside a final plastic molded product by first mineralizing and fixing the captured carbon dioxide (CO₂) into high-purity precipitated calcium carbonate (CaCO₃) and then introducing it as a resin substitute composite raw material in a plastic compounding process.

[0076] Since calcium carbonate isolated in a solid state is uniformly dispersed and bonded within the plastic polymer matrix, the possibility of decomposition and carbon re-release in natural conditions is fundamentally blocked, thereby maintaining a semi-permanent carbon fixation effect unless high-temperature thermal decomposition (above 800°C) occurs.

[0078] The present invention provides a method for calculating and controlling greenhouse gas reduction amount, comprising the following steps using the greenhouse gas reduction amount calculation and control system (100) above.

[0079] In one embodiment, the present invention comprises the step of: (a) a data collection control unit (10) actively controlling a downstream ring blower inverter and a bypass valve according to real-time measurements of a pressure sensor and a flow rate sensor provided on the discharge side to prevent the risk of exhaust backflow of a boiler exhaust facility, thereby selectively introducing only a portion of the exhaust gas within a safe range into a collection facility, and measuring the piping area, flow rate, and carbon dioxide concentration of the introduced exhaust gas in real time;

[0080] (b) a step in which a calculation control unit (20) calculates a field correction weight defined as the product of the correlations of the flow rate ratio, cross-sectional area ratio, and carbon dioxide concentration ratio of laboratory-based reference process data and the field actual measurement data, and calculates the carbon capture saturation of a transport target solution in which carbon dioxide is overcaptured by a dedicated amine-based absorbent based on the weight, and dynamically estimates the transport cycle to an external resource recycling plant; and

[0081] (c) A reduction amount determination unit (30) sets a reference carbon capture amount based on the actual weight of the calcium carbonate (CaCO₃) solid that is finally precipitated and recovered through a reaction with calcium ions (Ca2+) after the solution to be transported is transported to an external resource recycling plant, and determines the final net greenhouse gas reduction amount by subtracting in real time project emissions, including emissions from the use of power from the operation of the field facility and emissions from the transport of the solution to the external resource recycling plant and the transport of the final calcium carbonate product by the electric truck.

[0082] In one embodiment, the method for calculating and controlling the reduction amount using the greenhouse gas reduction amount calculation and control system (100) of the present invention may include a step of controlling the amount of exhaust gas flowing into the capture facility (200) by linking the inverter (14) and the bypass valve (15). To ensure the operational safety of the exhaust facility, the present invention sets only a specific exhaust port of a portion of the total exhaust gas of the boiler exhaust facility as a target exhaust port for measurement, and controls the gas intake pressure by performing active control of the inverter (14) and the bypass valve (15) through the data collection control unit (10). Through this, only exhaust gas within a safe range is selectively introduced, and the CO₂ concentration, pipe area, and exhaust gas flow rate measured at the corresponding exhaust port are collected in real time, thereby deriving valid basic data for calculating the reference carbon capture amount calculated inversely from the immobilized calcium carbonate (CaCO₃).

[0083] The greenhouse gas reduction amount calculation and control system (100) of the present invention can perform a carbon saturation correction algorithm with field weights applied through a computation control unit (20).

[0084] In one embodiment, the present invention calculates a final site weight (0.01942) by combining the flow rate ratio, concentration ratio, and cross-sectional area ratio having a value of 0.793 relative to the standard (correlation multiplication) to reflect the difference in environmental scale between the actual conditions at a building site (CO₂ concentration 7.8%, flow rate 0.8 m / s) and the laboratory standard conditions (CO₂ concentration 99.9%, flow rate 2.55 m / s). Through this, the expected amount of carbon precipitation within the capture line can be preemptively estimated, and based on the calculated site weight, the carbon capture saturation of the transport target solution in which carbon dioxide is overcaptured by the dedicated amine-based absorbent can be calculated, thereby dynamically estimating and controlling the optimal transport cycle to an external resource recycling plant (300).

[0085] The greenhouse gas reduction amount calculation and control system (100) of the present invention can perform chemical stability verification of the solution state and leakage blocking logic through the reduction amount determination unit (30).

[0086] In one embodiment, the present invention confirms that, based on the reaction characteristics of a dedicated amine-based absorbent in which a composite control agent (Lycel B) is mixed with a main absorbent (Lycel A), the oxidative degradation of amine molecules in the absorbent liquid is suppressed, thereby ensuring that the captured carbon dioxide (CO₂) does not spontaneously re-emitted in the solution state and maintains a stable bonded state. By utilizing the principle of vapor-liquid equilibrium achieved in the gaseous space inside a sealed container (210) at a building site, the reliability of the reduction amount calculation can be determined by converging the carbon leakage amount variable to '0' in the storage stage before transfer to an external resource recycling plant (300) as well as in the transportation stage while maintaining the same sealed conditions.

[0087] The greenhouse gas reduction amount calculation and control system (100) of the present invention can derive an actual reduction amount based on LCA (life cycle assessment) by integrating it through the reduction amount determination unit (30).

[0088] In one embodiment, the present invention aggregates in real time the power consumption of a ring blower motor (13), pressure sensor (11), flow rate sensor (12), inverter (14), and bypass valve (15) included in a building site-side data collection control unit (10), and the process power consumption (Scope 2 emissions) of an external resource recycling plant (300) facility. In addition, the transport emissions reflecting the emission factor (0.067 tCO₂eq / t CaCO₃) based on the travel distance for transporting the supercapture solution and the final calcium carbonate (CaCO₃) product using an electric truck are integrated in real time as project emissions (PE) along with the power consumption emissions, and the final net greenhouse gas reduction (ER) can be determined by subtracting the project emissions (PE) in real time from the reference carbon capture amount (BE) based on the mass of the final precipitated calcium carbonate.

[0089] FIG. 3 is a chart of actual measurement-based data that records, in real-time or periodically, the actual flow rate data of exhaust gas selectively introduced within a safe range from a specific outlet (111) according to the operation of the boiler exhaust facility (110) and the gas (LNG) usage (m3) linked thereto, in order to derive the 'reference carbon capture amount (BE)' which serves as the basis for calculating and controlling the greenhouse gas reduction amount of the present invention. According to the methodology of the present invention, statistical theoretical emissions based on the total fossil fuel consumption of the hot water boiler are not used as a unilateral standard. Instead, the risk of backflow is controlled through the ring blower and inverter control of the data collection control unit (10), and the actual flow rate data of exhaust gas introduced from a specific outlet (111) ('sum of inflow corresponding usage of Boiler 1 and Boiler 2' exemplified in FIG. 3) is used as the basis, and the primary carbon mass at the inflow stage is calculated by mathematically combining the 'LNG net calorific value coefficient' and 'carbon emission coefficient' of the Ministry of Environment and the Korea Environment Corporation's notification standards. Furthermore, the pure mass of CO₂, which is transferred to the external resource recycling plant (300) and finally converted and immobilized into calcium carbonate (CaCO₃), is back-calculated to calculate the secondary carbon mass. Subsequently, the reduction amount determination unit (30) determines the final reference carbon capture amount (BE) by ensuring data integrity through mutual matching and cross-checking the primary carbon mass (theoretical value) based on the incoming gas and the secondary carbon mass (measured value) based on the calcium carbonate solid.

[0090] This functions as a reference indicator for objectively and absolutely verifying the final net greenhouse gas reduction (ER) by comparing and subtracting the actual captured data, which is measured in real time through the pressure sensor (11) and flow rate sensor (12) within the data collection control unit (10) of the present invention, and the project emissions (PE), which include facility power emissions and electric truck transport emissions.

[0091] FIG. 4 shows the results of real-time carbon dioxide capture performance monitoring and analysis according to the reaction conditions of a dedicated amine-based absorbent according to one embodiment of the present invention. The analysis results are used as verification basic data to calculate the net reduction amount (ER) by comparing it with the project emission amount (PE) in the reduction amount determination unit (30).

[0092] The system and method of the present invention apply the accredited 'National Institute of Environmental Science Notification Method (TIC Analysis)' to overcome the error of the simple solid weight measurement method at the final product determination stage. Through this, the final isolation efficiency of the liquid carbon solution collected at the building site and converted into solid calcium carbonate (CaCO₃) via an external resource recycling plant (300) can be engineered to verify.

[0093] The results of the Total Inorganic Carbon (TIC) analysis to verify the control of leakage emissions and integrity in the mineralization conversion process of captured carbon dioxide according to one embodiment of the present invention are shown in Table 1 below.

[0094]

[0095] As shown in Table 1, the TIC concentration of the dedicated amine-based absorbent stock solution (control group), which was in the basic state before capture, was measured at 16.8 mg / L. However, the TIC concentration of the super-captured solution (experimental group), which reached the carbon solubilization stage after capture was completed at the building site, increased dramatically to 32,300.0 mg / L, proving that carbon dioxide was captured and combined with high efficiency. Subsequently, after undergoing a primary resource recovery (solidification) reaction with calcium ions (Ca2+) and filtration at an external resource recycling plant (300), the residual concentration decreased to 9,270.0 mg / L, and the residual TIC concentration of the purified filtered solution after the final secondary resource recovery reaction was completed was 14.3 mg / L. This indicates that carbon was recovered at a level lower than the initial stock solution state (16.8 mg / L), and this result demonstrates that the efficiency of solid conversion and sequestration of carbon dioxide present in the liquid phase reached approximately 99.95%.

[0096] Based on this high-purity materialization data, the integrity of the net reduction data of the measurement-based life cycle assessment (LCA) model leading from 'capture-storage-segregation-final resource recovery' can be confirmed by converting the captured carbon into industrial calcium carbonate solid with a purity of 95% or higher and permanently immobilizing it.

[0097] FIG. 5 is a means for verifying the long-term carbon fixation of the capture methodology according to one embodiment of the present invention, and can confirm the irreversible carbon sequestration stability within a polymer matrix through the control of the particle size distribution of calcium carbonate (CaCO₃), which is the final mineralization resource.
