[0002] Carbon dioxide is considered one of the main greenhouse gases causing global climate change. Currently, countries around the world are working hard to reduce carbon dioxide emissions and exploring various methods to sequester and reduce the concentration of carbon dioxide in the atmosphere. Among them, a common method is to capture carbon dioxide from emission sources through carbon capture and storage technology and then sequester it in underground storage repositories. Traditional carbon dioxide capture technologies require a large amount of energy for absorbing and separating carbon dioxide, and at the same time produce a large amount of carbon dioxide waste gas emissions, which have a negative impact on the environment. Therefore, only by sequestering the captured carbon dioxide or converting it into useful chemicals or fuels can the recycling of resources be achieved, carbon dioxide emissions be reduced, energy consumption be lowered, and the goals of environmental protection and energy conservation be achieved.

[0028] The transmission device 106 is used to receive or send data via a network.

In one instance, the transmission device 106 includes a network adapter (Network Interface Controller, abbreviated as NIC), which can be connected to other network devices through a base station and thus can communicate with the Internet. In one instance, the transmission device 106 may be a radio frequency (Radio Frequency, abbreviated as RF) module, which is used to communicate with the Internet wirelessly.

[0029] In this embodiment, a method for treating carbon dioxide is provided. Figure 2 is a flowchart of a method for treating carbon dioxide according to an embodiment of the present application, as shown in Figure 2 . The process includes the following steps S202 - S206:

[0030] Step S202: Determine the capture amount corresponding to the first device and the sequestration amount corresponding to the second device within a preset period, where the first device is a device for capturing carbon dioxide, and the second device is a device for sequestering carbon dioxide;

[0031] Step S204: Calculate the remaining amount of the capture amount and the sequestration amount, where the remaining amount is the part by which the capture amount exceeds the sequestration amount;

[0032] Step S206: When the remaining amount is greater than a preset threshold, determine to transfer the remaining amount of carbon dioxide to a conversion device for conversion processing.

[0033] In the above steps, the capture amount corresponding to the first device and the storage amount corresponding to the second device within a preset period are determined, where the first device is a device for capturing carbon dioxide, and the second device is a device for storing carbon dioxide; the remaining amounts of the capture amount and the storage amount are calculated, where the remaining amount is the part by which the capture amount exceeds the storage amount; when the remaining amount is greater than a preset threshold, it is determined that the remaining carbon dioxide is transferred to a conversion device for conversion processing. This solves the problem of being unable to balance the energy consumption and carbon dioxide emissions during the carbon dioxide capture process. Furthermore, by storing or converting the captured carbon dioxide into useful chemicals or fuels, the recycling of resources is achieved, carbon dioxide emissions are reduced, energy consumption is lowered, and the purposes of environmental protection and energy conservation are achieved.

[0034] Optionally, assume that within a preset period, the first device successfully captures 100 tons of carbon dioxide, while the second device can only store 80 tons of carbon dioxide. According to the above requirements, the remaining amounts of the capture amount and the storage amount can be calculated as 100 tons - 80 tons = 20 tons. Since the remaining amount is greater than the preset threshold (assuming the preset threshold is 10 tons), the 20 tons of the remaining carbon dioxide can be transferred to a conversion device for conversion processing. For example, if the conversion device has a conversion limit, for instance, it can complete the chemical conversion of up to 15 tons of carbon dioxide into methane at most, then the finally un-converted part can be transported through a pipeline to a vent riser and re-emitted into the atmosphere.

[0035] In an exemplary embodiment, after determining that the remaining carbon dioxide is transferred to a conversion device for conversion processing when the remaining amount is greater than a preset threshold, the method further includes: obtaining the conversion efficiency of the conversion device connected to the capture device and the storage device; determining the target amount of carbon dioxide consumed based on the conversion efficiency and the duration corresponding to the preset period; comparing the target amount with the remaining amount to determine the processing strategy for the remaining amount.

[0036] It can be understood that by obtaining the conversion efficiency of the conversion device, the situation of carbon dioxide processing can be grasped more accurately, and the processing efficiency can be improved. According to the comparison between the target amount and the remaining amount, the processing strategy can be adjusted in a timely manner to ensure that the carbon dioxide is effectively processed and to avoid over-processing or under-processing. Determining the target consumption amount by a quantitative method is conducive to monitoring and adjusting the carbon dioxide processing process and improving the accuracy and effect of processing.

[0037] In an exemplary embodiment, the target quantity is compared with the remaining quantity to determine a processing strategy for the remaining quantity, including: when the target quantity is less than the remaining quantity, determining to transfer a part of the remaining quantity that cannot be subjected to conversion processing to a venting device, where the venting device is used to gasify carbon dioxide and release it into the atmosphere; when the target quantity is greater than or equal to the remaining quantity, determining to continuously use the conversion device to convert the carbon dioxide in the remaining quantity.

[0038] It can be understood that by adopting different processing strategies according to different situations of the target quantity and the remaining quantity, different situations can be flexibly handled. When the target quantity is greater than or equal to the remaining quantity, continuously using the conversion device to process the remaining quantity can ensure that all the carbon dioxide in the remaining quantity is effectively converted and processed, avoiding any waste or emission of carbon dioxide. When the target quantity is less than the remaining quantity, transferring a part of the remaining quantity that cannot be converted and processed to the venting device and releasing it into the atmosphere can ensure that the remaining carbon dioxide does not cause too much negative impact on the environment.

[0039] In an exemplary embodiment, after determining to continuously use the conversion device to convert the carbon dioxide in the remaining quantity, the method further includes: calculating the target heat energy required for the conversion device to convert the carbon dioxide in the remaining quantity; determining a first heat energy corresponding to the waste heat of the flue gas and a second heat energy corresponding to the renewable electrothermal energy during the power generation process of a target power plant connected to the capture device; determining the auxiliary heat energy to be added to the conversion device during the conversion process according to the first heat energy, the second heat energy, and the target heat energy, where the auxiliary heat energy is the heat energy generated by operating the heating components in the conversion device.

[0040] It can be understood that by utilizing the waste heat of the flue gas and the renewable electrothermal energy of the target power plant, energy waste can be reduced and the utilization efficiency of resources can be improved. By calculating the required target heat energy and utilizing the auxiliary heat energy, the energy consumed during the conversion process can be effectively reduced and the energy cost can be lowered. Utilizing renewable energy and waste heat as heat sources helps to reduce carbon dioxide emissions and the impact on the environment, which is in line with the concept of environmental protection and energy conservation. Generally speaking, this method makes full use of resources during the carbon dioxide conversion process, reduces energy consumption, can not only meet the energy requirements of the conversion device, but also achieve the purpose of environmental protection and energy conservation.

[0041] In an exemplary embodiment, determining the auxiliary thermal energy to be added to the conversion device during the conversion process according to the first thermal energy, the second thermal energy, and the target thermal energy includes: subtracting the first thermal energy and the second thermal energy from the target thermal energy to obtain a remaining thermal energy value; when determining that the remaining thermal energy value is greater than or equal to zero, determining that the auxiliary thermal energy to be added to the conversion device during the conversion process is zero; when determining that the remaining thermal energy value is less than zero, determining that the auxiliary thermal energy to be added to the conversion device during the conversion process is the remaining thermal energy value.

[0042] It can be understood that by accurately calculating the target thermal energy, the first thermal energy, and the second thermal energy, it is possible to ensure that the required auxiliary thermal energy during the conversion process is accurately determined. By determining the increase in auxiliary thermal energy according to the magnitude of the remaining thermal energy value, unnecessary energy waste can be avoided, and the effective utilization of energy can be achieved. Determining whether to add auxiliary thermal energy according to whether the remaining thermal energy value is greater than zero makes the operation process simpler and more efficient.

[0043] In an exemplary embodiment, after determining to transfer the remaining amount of carbon dioxide to the conversion device for conversion processing when the remaining amount is greater than a preset threshold, it includes: obtaining the conversion result of the conversion device for the remaining amount of carbon dioxide; determining the target content of the target product generated by the conversion device according to the conversion result, where the target product is generated by a chemical reaction of carbon dioxide.

[0044] It can be understood that by converting the carbon dioxide in the remaining amount, the emission of carbon dioxide in the atmosphere can be effectively reduced, which is beneficial to environmental protection. Converting the carbon dioxide in the remaining amount into a useful target product realizes the reuse and recycling of resources. By analyzing the conversion result and determining the target content of the target product, the conversion process can be better controlled, and the production efficiency and product quality can be improved. In short, by converting the carbon dioxide in the remaining amount and determining the target content of the target product according to the conversion result, the resource utilization of carbon dioxide and environmental protection can be effectively achieved.

[0045] Obviously, the above-described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. To better understand the above method, the following describes the above process in conjunction with embodiments, but does not limit the technical solutions of the embodiments of the present application. Specifically:

[0046] An optional embodiment of the present application provides a management method for integrated carbon dioxide capture and conversion to address the issue of imbalance between energy consumption and carbon dioxide emissions during the carbon dioxide capture process. This method involves obtaining the first efficiency of the capture device for carbon dioxide capture and the second efficiency of the sequestration device for injecting carbon dioxide; estimating the capture amount and sequestration amount within the target time period. When the sequestration amount is less than the capture amount, the amount of carbon dioxide to be consumed is determined, and this portion of carbon dioxide is input into the conversion system for methane conversion. Before conversion, it is also necessary to determine the carbon dioxide conversion amount that the current conversion system can complete within the target time period, thereby balancing the consumption of captured carbon dioxide, preventing the re-release of captured carbon dioxide into the atmosphere, and reducing the power consumption of the power plant.

[0047] Optionally, an integrated carbon dioxide capture and conversion system is a system that comprehensively utilizes different technical means to reduce carbon dioxide emissions and convert it into valuable compounds. Figure 3 is a schematic structural diagram of an integrated carbon dioxide capture and conversion system according to an embodiment of the present application; the above system includes at least in-situ catalytic conversion 32, moving bed 34, fixed bed 36, and circulating fluidized bed 38.

[0048] Optionally, for in-situ catalytic conversion 32, in-situ catalytic conversion refers to a technology that directly adds a catalyst during the combustion process to promote the conversion of carbon dioxide into useful compounds. Through the action of the catalyst, the conversion efficiency can be improved and energy consumption can be reduced.

[0049] Optionally, for moving bed 34, a moving bed refers to a technology that continuously replaces the adsorbent or catalyst in the reactor to achieve continuous reaction, which can improve the reaction efficiency and extend the service life of the reactor.

[0050] Optionally, for fixed bed 36, a fixed bed refers to a technology that fixes the adsorbent or catalyst in a fixed position in the reactor and allows the gas or liquid in the bed to react with the fixed bed through gas flow or liquid flow, which is suitable for stable reaction conditions.

[0051] Optionally, for circulating fluidized bed 38, a circulating fluidized bed is a technology that suspends solid particles in the reactor through gas flow and achieves circular motion, which can increase the contact area between reaction materials and improve the reaction efficiency.

[0052] It should be noted that when performing in-situ catalysis, attention should be paid to the selection and performance of the catalyst to ensure the ability to efficiently convert carbon dioxide. At the same time, attention should be paid to the stability and lifespan of the catalyst to avoid the inactivation of the catalyst affecting the operating efficiency of the system. For the moving bed, it is necessary to ensure a reasonable design of the moving bed to achieve efficient adsorption and desorption of carbon dioxide. At the same time, attention should be paid to the operating stability and durability of the moving bed to avoid blockage or wear of the moving bed affecting the normal operation of the system. For the fixed bed, it is necessary to ensure the selection of appropriate packing for the fixed bed to achieve efficient adsorption and conversion of carbon dioxide. At the same time, attention should be paid to the design parameters and operating conditions of the fixed bed to ensure the operating efficiency and stability of the fixed bed. For the circulating fluidized bed, attention should be paid to the operating parameters and gas-solid separation effect of the circulating fluidized bed to ensure that the circulating fluidized bed can achieve efficient gas-solid mass transfer and reaction. At the same time, attention should be paid to the operating stability and safety of the circulating fluidized bed to avoid safety problems such as leakage and explosion of the gas-solid mixture.

[0053] As an alternative implementation method, Figure 4 is a flowchart of a management method for carbon dioxide capture and conversion integrated according to an embodiment of the present application. The specific steps are as follows:

[0054] Step 1: Obtain the first efficiency of the capture device for capturing carbon dioxide and the second efficiency of the sequestration device for injecting carbon dioxide;

[0055] Step 2: Estimate the capture amount and sequestration amount within the target time period. When the sequestration amount is less than the capture amount, determine the amount of carbon dioxide to be consumed;

[0056] Step 3: Determine the amount of carbon dioxide conversion that the conversion system can complete within the target time period;

[0057] Step 4: Input the carbon dioxide to be consumed into the conversion system for methane conversion;

[0058] Step 5: Produce useful products. The products after conversion can be used to produce chemicals, fuels or other useful products. These products can be used in industrial production, energy storage or other fields.

[0059] Optionally, methanation technology is a technology that reacts carbon dioxide and hydrogen to produce methane compounds. This technology can effectively convert waste carbon dioxide into useful methane compounds, thereby reducing greenhouse gas emissions and carbon emissions. This technology can be applied in industrial production processes or used to produce alternative fuels or chemical products. Through methanation technology, carbon recycling can be achieved, reducing dependence on fossil fuels and promoting sustainable development.

[0060] Optionally, methanation technology can be combined with the steel industry to convert flue gas CO 2After being converted into methane, it can be used as a fuel in the blast furnace smelting process to replace traditional high-temperature fuels such as coal. In addition, methane can also be applied to iron-making gas generators. This is because methane, as an important raw material in iron-making gas generators, can react with steam, etc. to produce fuel gases such as carbon monoxide (CO) and hydrogen (H) 2 which can be used for smelting. The reverse water-gas shift technology can be combined with chemical production processes. For example, in the production process of ethylene, steam cracking is usually used to produce ethylene from hydrocarbon raw materials (such as ethane, propane, etc.). During the steam cracking process, in addition to producing ethylene, a certain amount of CO 2 is produced as a by-product. These CO 2 can be captured and converted into useful chemicals and fuels. At this time, the reverse water-gas shift can reverse-react the captured CO 2 and hydrogen to produce CO and water vapor. The generated CO can be used as a reducing agent in the ethylene production process to promote the synthesis reaction of ethylene.

[0061] Optionally, the combination with coal-fired power plants may be another promising combination method for the reverse water-gas shift technology. However, when combining with coal-fired power plants, various factors need to be considered, including the fuel type of the power plant, the oxygen concentration in combustion, etc. For example, the CO 2 concentration in the flue gas generated by conventional air-concentration combustion is 10%-15%, while that of oxy-fuel combustion may reach more than 20%. The former is suitable for CaO-based bifunctional materials, and the latter may be more compatible with MgO-based bifunctional materials. In addition, the heat source is also an important factor worthy of consideration, which involves providing suitable high-temperature conditions for the operation process. Currently, more suitable heat sources applied to the reverse water-gas shift technology include flue gas waste heat and renewable electric heat. Flue gas waste heat can further improve the energy efficiency of the power plant, and renewable electric heat can convert waste electricity that cannot be incorporated into the power grid into electric heat to supply energy for the reverse water-gas shift technology. Therefore, the combination of the reverse water-gas shift technology and renewable energy can better address issues such as the instability and intermittency of renewable energy power generation, help solve the energy storage problem of renewable energy, and promote the sustainable development of renewable energy.

[0062] In summary, in the alternative embodiment of the present application, the process of controlling carbon dioxide emissions is achieved by acquiring a capture device and a storage device. First, the capture device can effectively capture carbon dioxide, and the storage device can store the captured carbon dioxide underground or elsewhere, thereby achieving the effect of reducing carbon dioxide emissions. Through the cooperation of the capture device and the storage device, the emission of carbon dioxide can be effectively controlled, and the capture and storage efficiency can be improved. When the storage amount is less than the capture amount, by inputting the carbon dioxide to be consumed into a conversion system for methane conversion, the captured carbon dioxide is prevented from being released back into the atmosphere, realizing the recycling of carbon dioxide and reducing emissions. Based on the capture amount and storage amount within the estimated target time period, by reasonably allocating and converting carbon dioxide, the effective control of carbon dioxide emissions can be achieved, avoiding energy waste and environmental pollution.

[0063] Through the description of the above embodiments, those skilled in the art can clearly understand that the method according to the above embodiments can be implemented by means of software plus a necessary general hardware platform. Of course, it can also be implemented by hardware, but in many cases the former is a better implementation method. Based on such an understanding, the technical solution of the present application, in essence, or the part that contributes to the prior art, can be embodied in the form of a software product. The computer software product is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk), and includes several instructions for causing a terminal device (which can be a mobile phone, computer, server, or network device, etc.) to execute the methods of the various embodiments of the present application.
