Description

[0046] Additional aspects and advantages of the present disclosure will be in part apparent and in part pointed out hereinafter. BRIEF DESCRIPTION OF DRAWINGS

[0047] The above and / or additional aspects and advantages of the present disclosure will become apparent and be readily appreciated from the following description, taken in conjunction with the accompanying drawings, in which:

[0051] Embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. Examples of the embodiments are shown in the drawings, in which the same or similar reference numerals indicate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below are exemplary and are intended to explain the present disclosure, and cannot be understood as a limitation of the present disclosure.

[0052] The present disclosure is described in detail below in conjunction with specific embodiments.

[0053] In the first embodiment, as shown in Figure 1 , Figure 1A flowchart of a control method of a carbon capture system provided by an embodiment of the present disclosure is shown. The method can be implemented by a computer program and can be run on a device for controlling the carbon capture system. The computer program can be integrated in an application or run as a standalone tool application.

[0054] The control device of the carbon capture system can be an electronic device having a control function of the carbon capture system.

[0055] The control method of the carbon capture system can be executed by the electronic device.

[0056] In an example, the control method of the carbon capture system includes the following steps.

[0057] S101, during the startup phase of the carbon capture system, obtaining a solution temperature of a solution in a regenerator of the carbon capture system, and heating the solution until the solution meets a carbon dioxide desorption requirement, and controlling the carbon capture system to enter a working state and introduce flue gas into the regenerator.

[0058] According to some embodiments, the carbon dioxide desorption requirement refers to a requirement used when determining whether the solution in the regenerator reaches a maximum carbon dioxide desorption rate.

[0059] S102, during the shutdown phase of the carbon capture system, heating the solution until a first carbon dioxide loading value in the solution meets a first carbon dioxide loading requirement.

[0060] It should be noted that during the shutdown phase of the carbon capture system, flue gas is no longer introduced into the regenerator. At this time, the solution in the regenerator is heated to further desorb carbon dioxide in the solution. This can increase the carbon dioxide production while reducing the first carbon dioxide loading in the solution, so that the solution in the regenerator can more quickly absorb carbon dioxide in the flue gas when the carbon capture system is started next time, thereby improving the carbon dioxide absorption rate when the carbon capture system is started next time.

[0061] In some embodiments, the first carbon dioxide loading requirement refers to a requirement used when determining whether the carbon dioxide in the solution can be further desorbed.

[0062] In summary, the method provided in the embodiment can obtain the solution temperature of the solution in the regenerator in the carbon capture system during the startup stage of the carbon capture system, heat the solution until the solution meets the carbon dioxide desorption requirement in the case that the solution temperature does not meet the carbon dioxide desorption requirement, control the carbon capture system to enter the working state and introduce flue gas into the regenerator, and thus the solution in the regenerator can be preheated before the flue gas is introduced into the regenerator, the solution temperature of the solution is raised to a temperature suitable for carbon dioxide desorption in advance, the flue gas resource loss can be reduced, and the time required for starting the carbon capture system can be reduced. During the shutdown stage of the carbon capture system, the solution is heated until the first carbon dioxide loading value in the solution meets the first carbon dioxide loading requirement, and thus the first carbon dioxide loading value in the solution in the regenerator in the next startup stage can be reduced, the carbon dioxide absorption efficiency of the absorber can be more favorably improved, the carbon dioxide content discharged into the atmosphere can be reduced, and the time required for starting the carbon capture system can be reduced.

[0063] The embodiment further provides another control method of a carbon capture system.

[0064] As shown in Figure 2 The control method of the carbon capture system can include the following steps:

[0065] S201, during the startup stage of the carbon capture system, obtaining the solution temperature of the solution in the regenerator in the carbon capture system and the second carbon dioxide loading value in the lean liquid in the absorber in the carbon capture system;

[0066] According to some embodiments, the solution temperature of the solution in the regenerator in the carbon capture system can be obtained by a temperature sensor, and the second carbon dioxide loading value can be obtained by sampling and analyzing the lean liquid in the absorber.

[0067] In some embodiments, the second carbon dioxide loading value of the lean liquid can be analyzed by using an online instrument.

[0068] S202, in the case that the solution temperature does not meet the carbon dioxide desorption requirement, heating the solution;

[0069] According to some embodiments, the carbon dioxide desorption requirement can be, for example, that the solution temperature is not less than the carbon dioxide desorption temperature. That is, in the case that the solution temperature is less than the carbon dioxide desorption temperature, the solution can be heated.

[0070] In some embodiments, the solution can be heated in at least one of the following ways:

[0071] controlling the first heating component in the regenerator reboiler to heat the solution;

[0072] The second heating assembly in the regenerative column kettle heats the solution.

[0073] According to some embodiments, the first heating assembly and the second heating assembly may, for example, employ energy storage batteries, daytime stored photo-thermal, etc. as heat sources.

[0074] In some embodiments, the carbon dioxide desorption temperature is not a fixed temperature. The carbon dioxide desorption temperature may, for example, be 90 degrees, the carbon dioxide desorption temperature may, for example, be 110 degrees, and the carbon dioxide desorption temperature may, for example, be between 90 degrees and 110 degrees.

[0075] S203, in the case where the second carbon dioxide loading value does not meet the second carbon dioxide loading requirement, adjusting the second carbon dioxide loading value;

[0076] According to some embodiments, the second carbon dioxide loading requirement may, for example, be that the second carbon dioxide loading value is between a first carbon dioxide loading threshold and a second carbon dioxide loading threshold, where the first carbon dioxide loading threshold is less than the second carbon dioxide loading threshold.

[0077] That is, in the case where the second carbon dioxide loading value is less than the first carbon dioxide loading threshold or the second carbon dioxide loading value is greater than the second carbon dioxide loading threshold, it can be determined that the second carbon dioxide loading value does not meet the second carbon dioxide loading requirement.

[0078] In some embodiments, the first carbon dioxide loading threshold and the second carbon dioxide loading threshold are not fixed thresholds. The first carbon dioxide loading threshold and the second carbon dioxide loading threshold may, for example, be adjusted according to the actual application scenario.

[0079] For example, when monoethanolamine (MEA) is used as an absorbent in the absorption tower, the second carbon dioxide loading value is usually between 2 and 3 moles of carbon dioxide per mole of MEA, which may, for example, be used as a reference, but the actual second carbon dioxide loading value may, for example, vary according to the specific operating conditions and the type of absorbent, and the loading threshold range may, for example, be obtained through laboratory tests.

[0080] According to some embodiments, in the case where the second carbon dioxide loading value is less than the first carbon dioxide loading threshold, flue gas may, for example, be introduced into the absorption tower to increase the second carbon dioxide loading to not less than the first carbon dioxide loading threshold.

[0081] In some embodiments, in the case where the second carbon dioxide loading value is greater than the second carbon dioxide loading threshold, steam may, for example, be introduced into the absorption tower to reduce the second carbon dioxide loading to not greater than the second carbon dioxide loading threshold.

[0082] It should be noted that during the process of the carbon capture system in the starting stage, the second carbon dioxide loading value can be obtained every unit time, and according to the size relationship between the second carbon dioxide loading value and the first carbon dioxide loading threshold and the second carbon dioxide loading threshold, the flue gas or steam is selected to be introduced into the absorption tower, so that the second carbon dioxide loading value is kept between the first carbon dioxide loading threshold and the second carbon dioxide loading threshold.

[0083] S204, in the case that the solution meets the carbon dioxide desorption requirement and the second carbon dioxide loading value meets the second carbon dioxide loading requirement, the carbon capture system is controlled to enter the working state and the flue gas is introduced into the regeneration tower;

[0084] According to some embodiments, the heating value when the solution is heated and the adjustment value when the second carbon dioxide loading value is adjusted can be determined; according to the heating value and the adjustment value, the heating rate when the solution is heated and the adjustment rate when the second carbon dioxide loading value is adjusted are determined; the solution is heated according to the heating rate, and the second carbon dioxide loading value is adjusted according to the adjustment rate, so that the solution meets the carbon dioxide desorption requirement and the second carbon dioxide loading value meets the second carbon dioxide loading requirement at the same time. Therefore, the starting loss can be reduced.

[0085] In some embodiments, during the process of controlling the carbon capture system to enter the working state, the historical operation data of the carbon capture system can be determined; the historical operation data is analyzed to determine the optimal ratio between the steam flow when the steam is introduced into the absorption tower in the carbon capture system and the lean liquid flow rate in the carbon capture system; the carbon capture system is controlled to capture carbon dioxide according to the optimal ratio. Therefore, the performance of the carbon capture system can be improved.

[0086] It should be noted that after the current start-stop machine, the operation data in the current start-stop machine process can be put into the historical operation data, and the optimal ratio between the steam flow when the steam is introduced into the absorption tower and the lean liquid flow rate in the carbon capture system is iteratively learned, so that the performance can be gradually learned and improved through multiple iterations, and finally the rapid and accurate convergence can be realized, and the performance of the carbon capture system can be further improved.

[0087] S205, during the process of the carbon capture system in the shutdown stage, the solution is heated until the first carbon dioxide loading value in the solution is less than the third carbon dioxide loading threshold.

[0088] According to some embodiments, the solution can be heated in at least one of the following ways:

[0089] The first heating component in the regeneration tower reboiler is controlled to heat the solution;

[0090] The second heating element in the regeneration tower is controlled to heat the solution.

[0091] In some embodiments, the third carbon dioxide load threshold does not specifically refer to a fixed threshold. This third carbon dioxide load threshold can be adjusted, for example, according to the actual application scenario.

[0092] In summary, the method provided in this embodiment firstly acquires the solution temperature in the regeneration tower and the second carbon dioxide load value in the lean liquid of the absorption tower during the start-up phase of the carbon capture system. If the solution temperature does not meet the carbon dioxide desorption requirements, the solution is heated. If the second carbon dioxide load value does not meet the second carbon dioxide load requirements, the second carbon dioxide load value is adjusted. When both the solution temperature and the second carbon dioxide load value meet the requirements, the carbon capture system is controlled to enter the working state and flue gas is introduced into the regeneration tower. Therefore, by determining the flue gas introduction conditions based on the solution temperature in the regeneration tower and the second carbon dioxide load value in the lean liquid of the absorption tower, the carbon dioxide desorption rate after startup can be further improved. Next, during the shutdown phase of the carbon capture system, the solution is heated until the first carbon dioxide load value in the solution is less than the third carbon dioxide load threshold. Therefore, the first carbon dioxide load value in the solvent of the regeneration tower can be reduced during the next startup phase, which is more conducive to improving the carbon dioxide absorption efficiency of the absorption tower, reducing the amount of carbon dioxide emitted into the atmosphere, and reducing the startup time required for the carbon capture system.

[0093] To achieve the above embodiments, this disclosure also proposes a control device for a carbon capture system.
