[0031] As described in the background art, Electrochemical Amine Regeneration (EMAR) is an innovative technology for capturing and regenerating carbon dioxide (CO2) in industrial waste gases. In the process of Carbon Capture and Storage (CCS) or Carbon Capture, Utilization and Storage (CCUS), amine solutions are widely used due to their efficient CO2 absorption characteristics. However, the amine solution that has absorbed CO2 needs to be regenerated to restore its absorption capacity so that it can be recycled and the operating cost can be reduced. Traditional amine regeneration methods usually require the use of thermal energy, which not only has high energy consumption but also generates additional greenhouse gas emissions. The electrochemical amine regeneration technology uses an electrochemical process to replace or assist thermal regeneration. By electrolysis, the amine solution that has absorbed CO2 releases CO2 and the activity of the amine is restored. This process can be carried out at a lower temperature, significantly reducing energy consumption and improving the energy efficiency and economy of the entire carbon capture process. The core of the electrochemical amine regeneration technology lies in the design and operation of an electrochemical reactor, which contains two electrodes and an electrolyte solution containing amine. When an electric current passes through the reactor, the amine and CO2 in the solution participate in the electrochemical reaction, resulting in the release of CO2 in gaseous form while the amine is regenerated. By precisely controlling reaction conditions such as current intensity, voltage, temperature, and pH value, etc., the release efficiency of CO2 and the regeneration rate of the amine can be optimized, thereby improving the performance of the entire system. The proposal of the EMAR technology is a major improvement over the traditional amine regeneration technology. It is more environmentally friendly and energy-saving, providing a new way to achieve more efficient carbon capture and emission reduction. Especially in the context of pursuing a low-carbon economy and sustainable development, it has important application prospects. However, although the EMAR technology shows great potential in theory, its efficiency problem in practical applications limits its widespread use. Specifically, the efficiency of the EMAR process is restricted by the following factors: Fluctuation of ion concentration: The change in the concentration of amine ions and other ions in the electrolyte solution affects the conductivity of the solution, and thus affects the efficiency of the electrochemical reaction. Too low or too high ion concentration in the solution may lead to a slow reaction rate and low regeneration efficiency. Poor control of gas phase holdup: The fluctuation of the CO2 content in the gas phase affects the regeneration rate of the amine. Too high gas phase holdup will reduce the regeneration efficiency of the amine, while too low may waste energy and fail to fully utilize the absorption capacity of the amine. Insufficient regulation of temperature and pH value: Appropriate temperature and pH value are crucial for maintaining the absorption and desorption performance of the amine. Deviation of temperature or pH value from the optimal range will significantly reduce the regeneration efficiency of the amine. Lack of intelligent regulation mechanism: The existing EMAR systems often rely on preset parameters in process regulation and lack real-time monitoring and dynamic adjustment mechanisms. They cannot adjust the operating conditions in a timely manner according to the changes during the process, resulting in limited overall efficiency. Therefore, the common technical problem in the current EMAR technology is the low efficiency of electrochemical amine regeneration, which is mainly attributed to the deficiencies of the above factors and the lack of regulation mechanisms.Inefficiency not only limits the economy and practicality of the EMAR process but also affects its potential as an efficient CO2 capture technology.
[0032] In this embodiment, a method for regenerating an electrochemical amine is provided. Figure 2 It is a flowchart of an optional method for regenerating an electrochemical amine according to an embodiment of the present application. The process includes the following steps S200 - S220:
[0033] Step S200, when it is detected that the voltage between the two electrodes of the electrochemical conversion device is greater than the voltage threshold, detect the gas parameters and ion parameters in the electrochemical conversion device.
[0034] Among them, an electrolyte solution is accommodated in the electrochemical conversion device, and the electrolyte solution contains an amine solution and an organic amine absorbent. The electrochemical conversion device includes: An anode and a cathode: Inside the electrochemical reactor, there are an anode and a cathode, which are the basic places where electrochemical reactions occur. The material selection and design of the anode and cathode directly affect the reaction efficiency and stability. For example, the anode may use corrosion - resistant metal materials (such as platinum, titanium, etc.), while the cathode may use materials with high catalytic activity (such as nickel, carbon - based materials, etc.). Electrolyte solution: The electrolyte solution is a key component in the reactor, which contains an organic amine absorbent. The organic amine absorbent is used to absorb carbon dioxide (CO 2 ) and release CO 2 during the electrochemical regeneration process, realizing the regeneration cycle. The composition and concentration of the electrolyte solution have an important impact on the reaction efficiency and energy consumption. Gas diffusion layer: The gas diffusion layer is used to promote the diffusion and transmission of gases (such as CO 2 and hydrogen), improving the reaction efficiency.
[0035] Among them, the change in voltage can directly reflect the reaction state and efficiency during the electrochemical amine regeneration (EMAR) process. The increase in voltage usually means an increase in reaction resistance, which may be caused by factors such as changes in the concentrations of key ions such as amine ions and hydrogen ions, a decrease in the electrolyte conductivity, or the accumulation of bubbles on the electrode surface. The increase in voltage also means higher energy consumption, which is crucial for evaluating and optimizing the energy consumption of the entire process.
[0036] Specifically, when the electrochemical conversion device in the electrochemical amine regeneration process is operating, the system continuously monitors the change in the voltage between the two electrodes. Voltage, as a key parameter in the reaction process, can reflect the efficiency of the electrochemical reaction and possible abnormal states. Once it is detected that the voltage value exceeds the preset voltage threshold, this usually indicates that the reaction conditions deviate from the optimized state, and the system needs to conduct more in - depth detection to determine the specific reasons.
[0037] Exemplarily, voltage data between two electrodes is collected in real time through an integrated voltage sensor. The intelligent control system has a built-in voltage threshold setting, which is comprehensively determined based on various factors such as the characteristics of the reactor, the conductivity of the electrolyte solution, and experimental conditions. When the data fed back by the voltage sensor exceeds this threshold, the system immediately triggers subsequent gas parameter and ion parameter detection procedures to provide more comprehensive information for judging the reaction situation.
[0038] Step S210, determine the reaction situation in the electrochemical conversion device according to the gas parameters and ion parameters.
[0039] Specifically, in the case of abnormal voltage, the system further detects the gas parameters (mainly the gas phase content rate of CO2) and ion parameters (especially the concentration of amine ions) inside the electrochemical conversion device. These parameters are directly related to the regeneration efficiency of the amine and the overall reaction state, and are the key to evaluating whether the reaction is normal.
[0040] Exemplarily, an on-line gas analyzer is used to detect the proportion of CO2 in the internal gas of the device in real time, and an electrochemical sensor (such as an ion selective electrode) is used to monitor the concentration of amine ions in the electrolyte solution. All detected data is transmitted to the intelligent control system in real time for comprehensive analysis. The system can judge whether the reaction deviates from the normal range according to the changes in gas parameters and ion parameters, such as whether the absorption capacity of the amine decreases and whether the conductivity of the electrolyte solution changes.
[0041] Step S220, in the case of determining that the reaction situation in the electrochemical conversion device is abnormal, adjust the reaction environment in the electrochemical conversion device according to the gas parameters and ion parameters until the reaction situation in the electrochemical conversion device returns to normal.
[0042] Specifically, if it is found through the above detection that the reaction situation is abnormal, the system will take corresponding measures to adjust the reaction environment according to the specific values of the gas parameters and ion parameters to restore the normal state of the reaction. The goal of this process is to optimize the reaction conditions to ensure the regeneration efficiency of the amine and the stability of the whole process.
[0043] Exemplarily, the intelligent control system automatically executes corresponding regulation measures according to the analysis results of the gas parameters and ion parameters. For example, when the gas phase content rate of CO2 is too high, indicating that the amine solution is approaching saturation in absorbing CO2, the system will increase the gas flow rate to accelerate the discharge of CO2, thereby reducing the gas phase content rate and promoting the regeneration of the amine; when the concentration of amine ions is abnormal, the system will adjust the electrolyte conductivity by adding an appropriate amount of additives (such as KNO3) to improve the current distribution and promote the regeneration efficiency of the amine. Through these measures, the system can dynamically adjust the reaction environment until the voltage and reaction efficiency return to normal levels.
[0044] In this embodiment, by detecting the voltage between the two poles of the electrochemical conversion device, it is possible to determine whether the electrochemical reaction is proceeding normally. When the voltage between the two electrodes of the electrochemical conversion device is detected to be greater than the voltage threshold, it represents that the rate of the electrochemical reaction is too slow. Then, by detecting the gas parameters and ion parameters in the electrochemical conversion device, it is possible to determine whether an abnormal situation has occurred, so as to facilitate the timely discovery of reaction anomalies. When an abnormal situation is determined, the reaction environment can be adjusted according to the gas parameters and ion parameters, so that the reaction situation in the electrochemical conversion device returns to normal, ensuring the stability and efficiency of the reaction, avoiding the decrease in amine regeneration efficiency caused by abnormal reactions, and improving the controllability and safety of the electrochemical amine regeneration process. In summary, this method can effectively improve the efficiency of electrochemical amine regeneration by monitoring the parameters in the electrochemical conversion device and dynamically regulating the reaction environment according to the parameters.
[0045] In one embodiment, as Figure 3 shown, step S210, determine the reaction situation in the electrochemical conversion device according to the gas parameters and ion parameters. It includes: steps S300 - S330:
[0046] Step S300, detect the gas phase content rate of carbon dioxide gas in the electrochemical conversion device.
[0047] Specifically, during the electrochemical amine regeneration process, it is crucial to continuously monitor the gas phase content rate of carbon dioxide gas inside the electrochemical conversion device. This is because the level of the gas phase content rate directly reflects the situation of the amine solution absorbing CO2. A low content rate means that the CO2 content in the amine solution is relatively low, and there is still room for the absorption process. While a too high content rate may indicate that the amine solution is approaching saturation and the regeneration efficiency decreases.
[0048] Exemplarily, an online infrared gas analyzer or other suitable gas analysis equipment is used to continuously monitor the gas composition inside the electrochemical conversion device, especially the content of CO2. These devices can continuously provide gas phase content rate data, ensuring the real - time and accuracy of the data. The intelligent control system compares these data with the preset content rate threshold to determine whether the gas phase content rate is normal.
[0049] Step S310, when it is determined that the gas phase content rate of carbon dioxide gas is lower than the content rate threshold, determine that the gas phase content rate of carbon dioxide gas in the electrochemical conversion device is normal.
[0050] Specifically, when the detected gas phase content rate of carbon dioxide is lower than the preset content rate threshold, the system will determine that the gas phase content rate is at a normal level. This indicates that the amine solution still has sufficient absorption capacity and the electrochemical conversion device can continue to operate efficiently.
[0051] Exemplarily, the content ratio threshold is set based on experimental data and theoretical calculations, taking into account the absorption capacity and regeneration efficiency of the amine solution, as well as the operating efficiency of the electrochemical conversion device. When the gas-phase content ratio feedback by the on-line gas analyzer is lower than this threshold, the intelligent control system confirms that the gas-phase content ratio is normal and there is no need to immediately adjust the reaction environment.
[0052] Step S320, when it is determined that the gas-phase content ratio of carbon dioxide gas in the electrochemical conversion device is normal, detect the concentrations of various target ions in the electrolyte solution.
[0053] Specifically, after confirming that the carbon dioxide gas-phase content ratio is normal, the system continues to monitor the concentrations of various target ions in the electrolyte solution. These ions include amine ions, hydrogen ions, etc., and their concentration changes directly affect the efficiency and stability of the electrochemical reaction.
[0054] Exemplarily, use electrochemical sensors (such as ion-selective electrodes and pH meters) to real-time monitor the ion concentrations in the electrolyte solution. By comparing with the preset concentration range, determine whether the ion concentrations are maintained within the normal operating range. These data are also transmitted to the intelligent control system in real time as the basis for judging the reaction situation.
[0055] Step S330, when it is determined that the concentrations of various target ions in the electrolyte solution are all maintained within the corresponding concentration ranges, determine that the reaction situation in the electrochemical conversion device is normal.
[0056] Specifically, when both the gas-phase content ratio of the gas in the electrochemical conversion device and the ion concentrations in the electrolyte solution are within the normal ranges, the system will judge that the overall reaction situation is normal, which means that the electrochemical amine regeneration process is in an optimal or acceptable operating state.
[0057] Exemplarily, the intelligent control system is built-in with a reaction state judgment algorithm, which can comprehensively evaluate the reaction efficiency and stability of the electrochemical conversion device according to the real-time collected gas parameters and ion parameters. When all parameters are within the preset normal ranges, the system confirms that the reaction situation is normal and the electrochemical conversion device can continue to operate without additional adjustment measures.
[0058] In this embodiment, by continuously monitoring the gas-phase content fraction of carbon dioxide gas and the concentrations of various target ions in the electrolyte solution, the operating state of the electrochemical conversion device can be accurately evaluated. By continuously monitoring the gas-phase content fraction, the absorption capacity of the amine solution is ensured, and the decline in regeneration efficiency caused by CO2 saturation is avoided; real-time monitoring of ion concentrations helps to maintain the conductivity and pH value of the solution, ensuring the optimal state of the electrochemical reaction, thereby improving the overall regeneration efficiency and system stability. Real-time data monitoring provides a basis for adjusting the operating conditions of the electrochemical conversion device, such as gas flow rate, electrolyte composition, etc., which helps to optimize the reaction environment, reduce energy consumption under abnormal conditions, and improve economy and environmental protection. It is possible to perform precise analysis and judgment based on the real-time monitored gas and ion parameters, automatically confirm whether the reaction is normal, reduce the need for manual intervention, and improve the control accuracy and the automation level of the reaction process. In summary, through accurate monitoring of gas parameters and ion parameters, combined with intelligent judgment, real-time evaluation and control of the operating state of the electrochemical conversion device are achieved, effectively improving the efficiency and stability of electrochemical amine regeneration, optimizing the operating conditions, and providing a more efficient, controllable and environmentally friendly solution for CO2 capture technology.
[0059] In one embodiment, as Figure 4 shown, after detecting the gas-phase content fraction of carbon dioxide gas in the electrochemical conversion device in step S300, the method further includes: step S400, when it is determined that the gas-phase content fraction of carbon dioxide gas is normally higher than the content fraction threshold, determining that the reaction situation in the electrochemical conversion device is abnormal.
[0060] Specifically, when the electrochemical conversion device is operating, the gas-phase content fraction of the internal carbon dioxide gas is continuously monitored. When the detected gas-phase content fraction is higher than the preset content fraction threshold, the system determines that the reaction situation is abnormal. The setting of the content fraction threshold is based on various considerations such as the maximum absorption capacity of the amine solution, the efficiency of the electrochemical reaction, and the system stability.
[0061] Exemplarily, an online infrared gas analyzer or other gas analysis equipment is used to collect the CO2 content data in the gas in real time. The intelligent control system has a built-in content fraction threshold, and the determination of this threshold needs to comprehensively consider the regeneration efficiency of the amine, the absorption upper limit of CO2, and the optimal working conditions of the electrochemical reactor. When the CO2 gas-phase content fraction exceeds the content fraction threshold, the system immediately triggers the judgment of abnormal reaction situation, indicating that further adjustment measures are needed.
[0062] After detecting the concentrations of various target ions in the electrolyte solution in step S320, the method further includes: step S410, when it is determined that the concentration of at least one target ion in the electrolyte solution is outside the corresponding concentration range, determining that the reaction situation in the electrochemical conversion device is abnormal.
[0063] Specifically, the change in the ion concentration in the solution, especially the concentration of amine ions and hydrogen ions, directly affects the efficiency and stability of the electrochemical amine regeneration process. If it is detected that the concentration of at least one target ion exceeds its corresponding operating concentration range, the system also determines that the reaction condition is abnormal.
[0064] Exemplarily, an electrochemical sensor (such as an ion-selective electrode and a pH meter, etc.) is used to monitor the concentration of target ions in the electrolyte solution in real time. Similar to the monitoring of the content threshold, the data processing module performs real-time analysis on the target ion concentration data, compares it with the preset concentration range, and determines whether the ion concentration is normal. If it is found that the ion concentration exceeds the range, the intelligent control system will immediately identify that the reaction condition is abnormal and measures need to be taken for adjustment.
[0065] In this embodiment, by monitoring the CO2 gas phase content rate and the concentration of target ions in the electrolyte solution in real time, the operating state of the electrochemical conversion device can be accurately judged, and abnormal conditions can be detected in a timely manner. The monitoring mechanism can detect the excessive CO2 gas phase content rate or abnormal ion concentration at an early stage, providing key information for taking timely and effective control measures. By quickly responding when an abnormal condition occurs and adjusting the reaction environment (such as flow rate, electrolyte composition, etc.), it helps to maintain the optimal operating state of the electrochemical conversion device, avoiding the efficiency decline and system instability caused by condition deviation. The timely detection and correction of abnormal conditions reduce the energy consumption in the abnormal state, avoid unnecessary energy waste, thereby reducing the operating cost and improving the economy. Improvement of intelligence and automation level: The intelligent judgment based on real-time monitoring data reduces the need for manual intervention, improves the automation and intelligence level of the reaction process, and ensures the efficient and stable operation of the electrochemical conversion device. In summary, through the real-time monitoring of the CO2 gas phase content rate and the analysis of the ion concentration in the electrolyte solution, this technical solution can accurately judge the reaction condition of the electrochemical conversion device. Once an abnormality is found, measures can be quickly taken for adjustment, effectively improving the efficiency, stability and economy of the electrochemical amine regeneration process.
[0066] In one embodiment, as Figure 5 shown, in step S220, when it is determined that the reaction condition in the electrochemical conversion device is abnormal, according to the gas parameters and ion parameters, the reaction environment in the electrochemical conversion device is adjusted until the reaction condition in the electrochemical conversion device returns to normal. It includes: steps S500 - S510:
[0067] In step S500, when it is determined that the gas phase content rate of carbon dioxide gas is normally higher than the content rate threshold, the flow rate of the gas in the electrochemical conversion device is adjusted to accelerate the discharge of carbon dioxide gas in the electrochemical conversion device until the gas phase content rate of carbon dioxide gas is lower than the content rate threshold.
[0068] Specifically, when the gas-phase content rate of carbon dioxide gas in the electrochemical conversion device is abnormal, that is, higher than the set content rate threshold, it indicates that the ability of the amine solution to absorb CO2 is approaching saturation, affecting the efficiency of the electrochemical amine regeneration process. Therefore, the system needs to adjust the gas flow rate to accelerate the discharge of CO2, thereby reducing the gas-phase content rate and restoring the absorption ability of the amine solution.
[0069] Exemplarily, the intelligent control system compares the real-time gas-phase content rate data of the gas with the content rate threshold. Once it is confirmed that the content rate is higher than the threshold, the system automatically adjusts the gas flow rate. The adjustment of the flow rate is usually achieved by controlling the valve or pump for gas flow. For example, the flow rate is rapidly increased from a lower level (such as 50 L / min) to a higher level (such as 70 L / min) to increase the discharge rate of CO2 in the gas until the gas-phase content rate drops below the content rate threshold. When the system confirms that the gas-phase content rate of the gas returns to normal, the flow rate is gradually adjusted to an appropriate operating level.
[0070] Step S510, in the case where the concentration of at least one target ion in the electrolyte solution is outside the corresponding concentration range, a conductive additive is added to the electrolyte solution to increase the conductivity of the electrolyte solution until the concentrations of various target ions in the electrolyte solution are all maintained within the corresponding concentration ranges.
[0071] Specifically, if it is monitored that the concentration of at least one target ion in the electrolyte solution deviates from the normal range, such as too high amine ion concentration or too low hydrogen ion concentration, this will affect the efficiency and stability of the electrochemical reaction. To solve this problem, an appropriate amount of conductive additive needs to be added to the electrolyte solution to adjust the conductivity of the solution and promote the ion concentration to return to the normal level.
[0072] Exemplarily, after the intelligent control system determines that the ion concentration deviates from the normal range, it automatically starts the additive addition program. The selection of the conductive additive should consider not interfering with the electrochemical reaction and the regeneration of the amine, such as KNO3. The amount of the additive added needs to be determined according to the specific ion concentration deviation and the total volume of the electrolyte solution, generally controlled by an automatic dosing pump or valve. For example, 0.1 - 0.5 g of conductive additive is added per liter of electrolyte solution until the ion concentration is adjusted to the normal range and the conductivity of the solution returns to normal, which helps to improve the efficiency of the electrochemical reaction and the stable operation of the process.
[0073] In this embodiment, by dynamically adjusting the gas flow rate and the addition amount of the conductive additive in the electrolyte solution, it aims to optimize the gas phase content rate and ion concentration in the electrochemical amine regeneration process, so as to improve the regeneration efficiency and system stability. By increasing the gas flow rate, the CO2 gas phase content rate can be rapidly reduced, avoiding the decline in process efficiency caused by CO2 saturation, ensuring the full regeneration of the amine solution, and improving the overall CO2 capture and regeneration efficiency. Adding a conductive additive to adjust the solution conductivity helps to restore the ion concentration to the normal range, improve the conditions of the electrochemical reaction, ensure the continuity and stability of the reaction, and avoid the energy waste and the decline in amine regeneration efficiency caused by abnormal ion concentration. By precisely controlling the gas flow rate and the additive addition amount, unnecessary energy consumption is avoided, the operating cost is reduced, and the economy and environmental friendliness of the entire electrochemical conversion process are improved. In summary, by dynamically adjusting the gas flow rate and the solution conductivity, the problems of excessive CO2 gas phase content rate and abnormal ion concentration in the electrochemical amine regeneration process are effectively solved, the regeneration efficiency is significantly improved, the energy consumption is reduced, the stability and automation degree of the process are enhanced, and a more efficient, economical and intelligent solution is provided for the practical application of CO2 capture and emission reduction technologies.
[0074] In one embodiment, as Figure 6 shown, the method further includes: steps S600 - S630:
[0075] Step S600, detecting the temperature in the electrochemical conversion device.
[0076] Specifically, temperature is one of the key parameters affecting the electrochemical amine regeneration process. An appropriate temperature can promote the progress of the electrochemical reaction and improve the rates of CO2 absorption and amine regeneration. Therefore, real - time monitoring of the temperature inside the electrochemical conversion device to ensure that it is stably within the preset temperature range is crucial for maintaining the efficiency and stability of the process.
[0077] Exemplarily, a high - precision temperature sensor is used to continuously collect the temperature data inside the electrochemical conversion device. The temperature sensor should be placed at a position that can accurately reflect the temperature of the electrolyte solution, such as in the electrolyte solution or on the reactor wall. The collected temperature data is transmitted to the intelligent control system in real - time and compared with the preset temperature range to determine whether temperature adjustment is required.
[0078] Step S610, in the case where the temperature exceeds the preset temperature range, adjusting the temperature so that the temperature in the electrochemical conversion device remains within the preset temperature range.
[0079] Specifically, when the detected temperature exceeds the preset temperature range, the system will automatically start the temperature adjustment program and adjust the heating or cooling device according to the actual situation to restore the temperature to the appropriate operating range.
[0080] Exemplarily, temperature regulation is usually carried out by a heater or a cooling system. If the temperature is below the preset range, the heater will start to increase the temperature of the electrolyte solution; conversely, if the temperature is too high, the cooling system will be started to lower the solution temperature. The intelligent control system precisely controls the heating and cooling operations based on the data feedback from the temperature sensor and the response times of the heater and the cooling system, ensuring that the temperature is quickly and stably adjusted within the preset range.
[0081] Step S620, detect the acidity and alkalinity in the electrochemical conversion device.
[0082] Specifically, the acidity and alkalinity (pH value) directly affect the regeneration efficiency of the amine in the solution and the speed of the electrochemical reaction. By monitoring the acidity and alkalinity in real time, it can be ensured that the pH value in the electrolyte solution is maintained at the optimal level suitable for amine regeneration and electrochemical reaction, thereby improving the efficiency and stability of the process.
[0083] Exemplarily, a pH sensor is used to monitor the acidity and alkalinity of the electrolyte solution in real time, and the pH sensor needs to be calibrated regularly to ensure the measurement accuracy. Similar to temperature monitoring, the intelligent control system receives the real-time pH value data and compares it with the preset acid-base range to determine whether it is necessary to adjust the acidity and alkalinity of the solution.
[0084] Step S630, when the acidity and alkalinity exceed the acid-base range, add a regulator to the electrolyte solution to keep the acidity and alkalinity within the acid-base range.
[0085] Specifically, when the acidity and alkalinity exceed the preset acid-base range, the system will automatically add the corresponding regulator, such as an acidic or alkaline solution, to adjust the pH value of the electrolyte solution to ensure that it is restored to the level suitable for amine regeneration and electrochemical reaction.
[0086] Exemplarily, the intelligent control system automatically starts the regulator addition program based on the monitoring result of the pH value. The choice of the regulator should be based on the expected direction of pH value adjustment. For example, if the pH value is too low, the system will automatically add an alkaline regulator; otherwise, an acidic regulator will be added. The addition amount of the regulator needs to be determined according to the total volume of the solution and the difference between the current pH value and the target pH value to ensure that the pH value is quickly and smoothly adjusted within the preset range.
[0087] In this embodiment, by real-time monitoring and precise control of temperature and pH, this technical solution can effectively optimize the operating conditions of the electrochemical amine regeneration process. The specific technical effects include: Optimization of temperature control: Ensure that the internal temperature of the electrochemical conversion device is stable within an appropriate operating range, promoting the rapid absorption of CO2 and the efficient regeneration of amines, and improving the efficiency and stability of the overall process. Energy consumption reduction: Through precise temperature control, unnecessary heating or cooling is avoided, energy waste is reduced, and operating costs are lowered. pH stability: Real-time monitoring and adjustment of the pH of the electrolyte solution ensure the optimal pH environment for amine regeneration and electrochemical reactions, further improving the regeneration efficiency and reaction rate. Enhancement of automation level: The intelligent control system can automatically adjust the temperature and pH value according to real-time monitoring data, reducing manual intervention, improving the accuracy and automation level of process control, and enhancing the stability and reliability of the system.
[0088] In one embodiment, as Figure 7 shown, the method further includes: Steps S700 - S730:
[0089] Step S700, determine the composition of the electrolyte solution according to the ion parameters.
[0090] Specifically, the composition of the electrolyte solution directly affects the efficiency of the electrochemical amine regeneration process. The system detects the ion parameters in the solution, such as the concentrations of amine ions, hydrogen ions, etc., to determine whether the composition of the electrolyte solution is normal, which provides a basis for the subsequent judgment of the content of the amine solution and the organic amine absorbent.
[0091] Exemplarily, an electrochemical sensor, such as an ion-selective electrode, is used to real-time monitor the ion concentration in the electrolyte solution. The sensor data is transmitted to the intelligent control system in real-time. The system presets the threshold of the normal range of ion concentration to judge the solution composition. If the detected ion concentration exceeds the preset range, the intelligent control system will start the subsequent adjustment program.
[0092] Step S710, determine the first content of the amine solution and the second content of the organic amine absorbent in the electrolyte solution according to the composition.
[0093] Specifically, after judging the composition of the electrolyte solution, the system further analyzes the first content of the amine solution (i.e., the concentration of amine ions in the solution) and the second content of the organic amine absorbent (i.e., the total concentration of the organic amine absorbent in the solution). The accurate determination of these two contents is the key step to adjust the solution composition and maintain the optimal absorption ratio.
[0094] Exemplarily, based on the ion parameters obtained in the first step and combined with the total volume and density of the electrolyte solution, the intelligent control system calculates the current contents of the amine solution and the organic amine absorbent. This calculation process generally involves converting the measured ion concentration into molar concentration, then calculating the molar ratio, and finally obtaining the actual contents of the amine solution and the organic amine absorbent through the conversion of the molar ratio and the total volume of the solution.
[0095] Step S720: Determine the target content range of the organic amine absorbent according to the first content of the amine solution and the preset absorption ratio.
[0096] Among them, the preset absorption ratio is used to indicate the optimal proportional relationship between the amine solution and the organic amine absorbent.
[0097] Specifically, in order to maintain the optimal absorption ratio during the electrochemical amine regeneration process, the system needs to determine the target content range of the organic amine absorbent according to the first content of the amine solution and the preset absorption ratio. The preset absorption ratio is based on theoretical calculations and experimental verifications, and reflects the optimal ratio for the amine solution and the organic amine absorbent to achieve the maximum absorption efficiency under specific conditions.
[0098] Exemplarily, the intelligent control system presets the optimal absorption ratio of the amine solution and the organic amine absorbent, and this ratio is related to the first content of the amine solution and the total volume of the electrolyte solution. The system calculates the target content range of the organic amine absorbent according to the current amine solution content and the optimal absorption ratio. The setting of the target content range takes into account the feasibility of actual operation, such as the addable amount of the solution and the minimum stirring amount.
[0099] Step S730: In the case where the second content of the organic amine absorbent exceeds the target content range, adjust the content of the organic amine absorbent so that the second content is within the target content range.
[0100] Specifically, when the detected content of the organic amine absorbent exceeds the target content range, the system starts the adjustment program, and adjusts the absorbent content to the optimal ratio range by adding or reducing the amount of the organic amine absorbent, thereby improving the efficiency and stability of the electrochemical amine regeneration process.
[0101] Exemplarily, the intelligent control system automatically adjusts the addition amount of the organic amine absorbent according to the comparison result between the second content and the target content range. For example, if the second content is lower than the lower limit of the target content range, the organic amine absorbent is automatically added; if it is higher than the upper limit, the content of the organic amine absorbent is reduced by diluting the solution or discharging an appropriate amount of the solution. The adjustment process needs to be precisely controlled to avoid imbalance of the solution components caused by over-adjustment.
[0102] In this embodiment, through real-time monitoring and intelligent regulation, the technical solution can accurately grasp the composition of the electrolyte solution during the electrochemical amine regeneration process and optimize the content ratio of the amine solution and the organic amine absorbent. The specific technical effects include: Maintaining the optimal absorption ratio: ensuring that the content ratio of the amine solution and the organic amine absorbent is within the preset optimal range, improving the efficiency of CO2 absorption and amine regeneration. Enhancing process stability: by adjusting the content of the organic amine absorbent in real time, avoiding the instability of the electrochemical amine regeneration process caused by composition imbalance and improving the reliability of the overall process. Controlling energy consumption and costs: precise control of the composition ratio reduces unnecessary consumption of the organic amine absorbent, avoids additional energy consumption caused by improper composition adjustment, and reduces the operating cost. Improving the level of automation and intelligence: the intelligent control system can automatically adjust the solution composition according to real-time monitoring data, reducing manual intervention, improving the accuracy and automation level of process control, and enhancing the stability and reliability of the system.
