Description

Technical Field

[0001] The present disclosure relates to the technical field of carbon capture, and in particular to a start-stop-canning coupling method, device, equipment and storage medium for capturing carbon dioxide. Background Art

[0002] During the operation of the carbon dioxide capture system, the startup and operation of the system are closely related to the maximum volume of the carbon dioxide storage tank. If after a period of operation, the carbon dioxide storage tank is full of liquid carbon dioxide, the carbon dioxide compressor should stop working immediately, and the entire carbon dioxide capture system should also stop working immediately; conversely, if the carbon capture system stops running and stops supplying heat to the regeneration tower, some carbon dioxide may still be desorbed from the regeneration tower using the waste heat in the tower and flow to subsequent carbon dioxide compressors. For small-scale carbon capture systems, the output of this part of carbon dioxide is small and will not cause serious impact on the surrounding environment or operators. However, for large-scale carbon capture projects, the output of carbon dioxide generated after shutdown is large, which may cause carbon dioxide poisoning to surrounding personnel. In addition, high-concentration carbon dioxide staying in the pipeline for a long time will cause corrosion to the equipment and affect the long-term use of the system. Summary of the invention

[0026] The regeneration tower is controlled to be in a non-working state, and the carbon dioxide escaping from the regeneration tower is discharged back to the absorption tower.

[0027] Optionally, until the carbon dioxide escaping from the regeneration tower does not meet the compression requirement, including:

[0028] Until the mass flow rate of carbon dioxide escaping from the regeneration tower is less than a mass flow rate threshold, wherein the mass flow rate threshold is determined by the mass flow rate of carbon dioxide output when the regeneration tower is in working state, and the mass flow rate threshold is less than the mass flow rate of carbon dioxide output when the regeneration tower is in working state.

[0046] Embodiments of the present disclosure are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0047] The present disclosure is described in detail below with reference to specific embodiments.

[0048] In the first embodiment, if Figure 1 As shown, Figure 1 This is a flow chart of a method for start-stop and canning coupling of carbon dioxide capture provided by an embodiment of the present disclosure. The method can be implemented by a computer program and can be run on a device for start-stop and canning coupling of carbon dioxide capture. The computer program can be integrated into an application or run as an independent tool application.

[0049] The carbon dioxide capture start-stop-canning coupling device may be an electronic device with a carbon dioxide capture start-stop-canning coupling function. The electronic device may be applied to a carbon capture system, for example.

[0050] Among them, the carbon dioxide capture start-stop-canning coupling method can be executed by an electronic device.

[0051] For example, the start-stop-tank coupling method for capturing carbon dioxide includes the following steps:

[0052] S101, determining the current amount of carbon dioxide captured in the carbon dioxide storage tank;

[0053] According to some embodiments, the carbon dioxide storage tank refers to a storage tank used to store carbon dioxide in a carbon capture system.

[0054] In some embodiments, the current carbon dioxide capture amount refers to the current carbon dioxide content in the carbon dioxide storage tank.

[0055] S102, if the current carbon dioxide capture amount meets the carbon dioxide tanking requirements, control the carbon dioxide compressor to stop compressing the carbon dioxide output from the regeneration tower into the carbon dioxide storage tank;

[0056] According to some embodiments, the CO2 tank filling requirement refers to a requirement used when stopping the delivery of CO2 to the CO2 storage tank.

[0057] S103, if the current carbon dioxide capture amount does not meet the carbon dioxide filling requirements and the regeneration tower is in a non-working state, the carbon dioxide compressor is controlled to compress the carbon dioxide escaping from the regeneration tower into the carbon dioxide storage tank until the carbon dioxide escaping from the regeneration tower does not meet the compression requirements.

[0058] According to some embodiments, the compression requirement refers to the requirement used when the carbon dioxide compressor stops compressing the carbon dioxide escaping from the regeneration tower into the carbon dioxide storage tank.

[0059] In some embodiments, if the current carbon dioxide capture amount does not meet the carbon dioxide filling requirements, but the regeneration tower is in working condition, the carbon dioxide compressor is controlled to compress the carbon dioxide output by the regeneration tower into the carbon dioxide storage tank until the current carbon dioxide capture amount meets the carbon dioxide filling requirements.

[0060] In some embodiments, if the carbon dioxide compressor is controlled to compress the carbon dioxide escaping from the regeneration tower into the carbon dioxide storage tank until the carbon dioxide escaping from the regeneration tower does not meet the compression requirements, and the current carbon dioxide capture amount meets the carbon dioxide tanking requirements, the carbon dioxide compressor is controlled to stop compressing the carbon dioxide output from the regeneration tower into the carbon dioxide storage tank.

[0061] In summary, the method provided in this embodiment detects the amount of carbon dioxide captured in the carbon dioxide storage tank and controls the carbon dioxide compressor according to the current amount of carbon dioxide captured in the carbon dioxide storage tank and the carbon dioxide filling requirements. It can couple the start and stop of the carbon capture system with the carbon dioxide filling problem, achieve flexible and intelligent regulation, reduce equipment corrosion caused by carbon dioxide accumulation, and endanger personnel safety.

[0062] This embodiment also provides another start-stop-canning coupling method for capturing carbon dioxide, which can be executed by an electronic device.

[0063] like Figure 2 As shown, the start-stop-tank coupling method for capturing carbon dioxide may include the following steps:

[0064] S201, determining the current operating time of the carbon dioxide compressor;

[0065] According to some embodiments, the current operating time refers to the current operating time when the carbon dioxide compressor delivers carbon dioxide to the carbon dioxide storage tank.

[0066] S202, determining the mass flow rate of carbon dioxide output from the regeneration tower during the current operation time;

[0067] According to some embodiments, the mass flow rate of the carbon dioxide output from the regeneration tower can be measured, for example, by a carbon dioxide mass flow meter installed at the carbon dioxide output port of the regeneration tower.

[0068] S203, determining the current amount of carbon dioxide captured in the carbon dioxide storage tank according to the current operating time and mass flow rate;

[0069] It should be noted that when the regeneration tower is in working condition, the pressure and temperature of the carbon dioxide output from its carbon dioxide output port can be regarded as approximately constant. For example, the carbon dioxide output from the carbon dioxide output port can be maintained at 2Kpa and ~90°C, that is, the mass flow rate of the carbon dioxide output from the carbon dioxide output port can be regarded as approximately constant. Therefore, the current carbon dioxide capture amount in the carbon dioxide storage tank can be determined based on the current operating time and mass flow rate.

[0070] In some embodiments, the current amount of carbon dioxide captured in the carbon dioxide storage tank may be determined, for example, according to the following formula:

[0071] m=ST

[0072] Wherein, m is the current carbon dioxide capture amount, S is the mass flow rate of carbon dioxide output from the regeneration tower, and T is the current operating time of the carbon dioxide compressor.

[0073] S204, determining a rated carbon dioxide capture amount corresponding to the carbon dioxide storage tank;

[0074] According to some embodiments, the rated carbon dioxide capture amount refers to an upper limit value of carbon dioxide that can be stored in a carbon dioxide storage tank.

[0075] In some embodiments, the carbon dioxide demand corresponding to the carbon capture system may be determined, and the rated carbon dioxide capture amount corresponding to the carbon dioxide storage tank may be determined based on the carbon dioxide demand. For example, the rated carbon dioxide capture amount may be equal to the carbon dioxide demand.

[0076] In some embodiments, the rated CO2 capture capacity can be adjusted by changing the size and design of the CO2 storage tank.

[0077] Taking a scenario as an example, assuming the design pressure is 2.4MPa and the temperature is -20℃, a variant of the ideal gas state equation can be used. Considering that the liquid carbon dioxide deviates less from the ideal behavior under these conditions, the carbon dioxide density in the carbon dioxide storage tank is as follows:

[0078] ρ CO2 =P / Rt=1140 kg / m3 (kg / m^3)

[0079] Among them, ρ CO2 is the density of carbon dioxide in the carbon dioxide storage tank; P is the design pressure, 2.4MPa=2.4×10^6Pa; R is the gas constant of carbon dioxide, 8.314J / (mol·K); t is the absolute temperature, -20℃=253.15K.

[0080] Therefore, the volume V of the carbon dioxide storage tank can be calculated according to the rated carbon dioxide capture capacity by the following formula:

[0081] V=M / ρ CO2

[0082] Where M is the rated carbon dioxide capture capacity.

[0083] For example, when the rated carbon dioxide capture capacity corresponding to the carbon dioxide storage tank is determined to be 2t of carbon dioxide demand, the volume V corresponding to the carbon dioxide storage tank can be calculated as 1.754m^3 according to the above formula.

[0084] It should be noted that, if the demand for carbon dioxide changes while the size of the carbon dioxide storage tank remains fixed, the corresponding rated carbon dioxide capture capacity can be adjusted by adjusting the design pressure of the carbon dioxide storage tank.

[0085] S205, determining a carbon dioxide capture amount threshold according to the rated carbon dioxide capture amount;

[0086] According to some embodiments, after the regeneration tower is in a non-working state, some carbon dioxide may still be desorbed from the regeneration tower using the waste heat in the regeneration tower and passed to the subsequent carbon dioxide compressor. Therefore, it is necessary to set the carbon dioxide capture amount threshold to be less than the rated carbon dioxide capture amount to reduce the large carbon dioxide production generated after shutdown, which may cause carbon dioxide poisoning to surrounding personnel, and the high concentration of carbon dioxide staying in the pipeline for a long time to corrode the equipment, affecting the long-term use of the system.

[0087] In some embodiments, the CO2 capture threshold does not specifically refer to a fixed threshold, and the CO2 capture threshold can be adjusted according to the actual application scenario, and it is only necessary to ensure that the CO2 storage tank is almost full but not full of liquid CO2 under the CO2 capture threshold. For example, the CO2 capture threshold can be 98%M or 97%M.

[0088] S206, if the current carbon dioxide capture amount is not less than the carbon dioxide capture amount threshold, the current carbon dioxide capture amount meets the carbon dioxide canning requirements;

[0089] For example, if m=98%M, it can be determined that the current carbon dioxide capture amount meets the carbon dioxide tanking requirements.

[0090] S207, if the current carbon dioxide capture amount meets the carbon dioxide tanking requirements, the carbon dioxide compressor is controlled to stop compressing the carbon dioxide output from the regeneration tower into the carbon dioxide storage tank, the regeneration tower is controlled to be in a non-working state, and the carbon dioxide escaping from the regeneration tower is discharged back to the absorption tower;

[0091] According to some embodiments, the regeneration tower is in a non-operating state when the regeneration tower stops heating to regenerate carbon dioxide. The regeneration tower can be controlled to be in a non-operating state by shutting down the reboiler at the bottom of the regeneration tower.

[0092] In some embodiments, the carbon dioxide escaping from the regeneration tower is discharged back to the absorption tower, where it can be further absorbed by the lean liquid in the absorption tower and will not be discharged back into the atmosphere, thereby further effectively reducing carbon emissions and reducing corrosion problems on equipment caused by accumulated carbon dioxide, while avoiding casualties caused by short-term excessive carbon dioxide concentrations.

[0093] S208, if the current carbon dioxide capture amount is less than the carbon dioxide capture amount threshold, the current carbon dioxide capture amount does not meet the carbon dioxide canning requirements;

[0094] For example, if m<98%M, it can be determined that the current carbon dioxide capture amount does not meet the carbon dioxide tanking requirements.

[0095] S209: If the current carbon dioxide capture amount does not meet the carbon dioxide filling requirements and the regeneration tower is in a non-working state, the carbon dioxide compressor is controlled to compress the carbon dioxide escaping from the regeneration tower into the carbon dioxide storage tank until the mass flow rate of the carbon dioxide escaping from the regeneration tower is less than the mass flow threshold, and the carbon dioxide escaping from the regeneration tower is discharged back to the absorption tower.

[0096] According to some embodiments, the mass flow threshold is determined by the mass flow of carbon dioxide output when the regeneration tower is in operation, and the mass flow threshold is less than the mass flow of carbon dioxide output when the regeneration tower is in operation. For example, the mass flow threshold may be 10%S.

[0097] In some embodiments, after the mass flow rate of carbon dioxide escaping from the regeneration tower is less than the mass flow rate threshold, the carbon dioxide escaping from the regeneration tower is discharged back to the absorption tower to be further absorbed by the lean liquid in the absorption tower, and will not be discharged back into the atmosphere, thereby further effectively reducing carbon emissions and reducing the corrosion problem of accumulated carbon dioxide on equipment, while avoiding casualties caused by short-term excessive carbon dioxide concentration.

[0098] It should be noted that if the carbon dioxide compressor is controlled to compress the carbon dioxide escaping from the regeneration tower into the carbon dioxide storage tank until the carbon dioxide escaping from the regeneration tower does not meet the compression requirements, and the current carbon dioxide capture amount is not less than the carbon dioxide capture amount threshold, the processing path is switched to step S207.

[0099] In summary, the method provided in this embodiment first determines the current operating time of the carbon dioxide compressor; determines the mass flow rate of carbon dioxide output by the regeneration tower during the current operating time; determines the current carbon dioxide capture amount in the carbon dioxide storage tank based on the current operating time and the mass flow rate; therefore, the accuracy of determining the current carbon dioxide capture amount can be improved. Next, by determining the rated carbon dioxide capture amount corresponding to the carbon dioxide storage tank; determining the carbon dioxide capture amount threshold value based on the rated carbon dioxide capture amount; if the current carbon dioxide capture amount is not less than the carbon dioxide capture amount threshold value, the current carbon dioxide capture amount meets the carbon dioxide canning requirements; if the current carbon dioxide capture amount is less than the carbon dioxide capture amount threshold value, the current carbon dioxide capture amount does not meet the carbon dioxide canning requirements; therefore, the accuracy of judging whether the current carbon dioxide capture amount meets the carbon dioxide canning requirements can be improved. Finally, if the current carbon dioxide capture amount meets the carbon dioxide filling requirement, the carbon dioxide compressor is controlled to stop compressing the carbon dioxide output from the regeneration tower into the carbon dioxide storage tank, the regeneration tower is controlled to be in a non-working state, and the carbon dioxide escaping from the regeneration tower is discharged back to the absorption tower; if the current carbon dioxide capture amount does not meet the carbon dioxide filling requirement, and the regeneration tower is in a non-working state, the carbon dioxide compressor is controlled to compress the carbon dioxide escaping from the regeneration tower into the carbon dioxide storage tank until the mass flow rate of the carbon dioxide escaping from the regeneration tower is less than the mass flow rate threshold, and the carbon dioxide escaping from the regeneration tower is discharged back to the absorption tower; therefore, the start and stop of the carbon capture system and the filling problem of carbon dioxide can be coupled to achieve flexible and intelligent regulation, reduce equipment corrosion caused by carbon dioxide accumulation, and reduce the safety of personnel at risk.

[0100] In order to implement the above-mentioned embodiments, the present disclosure also proposes a start-stop-tank coupling device for capturing carbon dioxide.

[0112] If the current carbon dioxide capture amount is not less than the carbon dioxide capture amount threshold, the current carbon dioxide capture amount meets the carbon dioxide tanking requirements;

[0113] If the current carbon dioxide capture amount is less than the carbon dioxide capture amount threshold, the current carbon dioxide capture amount does not meet the carbon dioxide filling requirements.

[0114] Optionally, when the control unit 302 is used to determine the rated carbon dioxide capture amount corresponding to the carbon dioxide storage tank, it is specifically used to:

[0115] Determine the amount of carbon dioxide required for the carbon capture system;

[0116] According to the demand for carbon dioxide, determine the rated carbon dioxide capture capacity corresponding to the carbon dioxide storage tank.

[0117] Optionally, the control unit 302 is used to, after the current carbon dioxide capture amount meets the carbon dioxide tanking requirement, further be used to:

[0118] The regeneration tower is controlled to be in a non-working state, and the carbon dioxide escaping from the regeneration tower is discharged back to the absorption tower.

[0119] Optionally, the control unit 302 is used to, until the carbon dioxide escaping from the regeneration tower does not meet the compression requirement, specifically to:

[0120] Until the mass flow rate of carbon dioxide escaping from the regeneration tower is less than a mass flow rate threshold, wherein the mass flow rate threshold is determined by the mass flow rate of carbon dioxide output when the regeneration tower is in working state, and the mass flow rate threshold is less than the mass flow rate of carbon dioxide output when the regeneration tower is in working state.

[0121] Optionally, the control unit 302 is used to, after the carbon dioxide escaping from the regeneration tower does not meet the compression requirement, further be used to:

[0122] The carbon dioxide escaping from the regeneration tower is discharged back to the absorption tower.

[0123] It should be noted that the aforementioned explanation of the embodiment of the start-stop-canned carbon dioxide capture coupling method is also applicable to the start-stop-canned carbon dioxide capture coupling device of this embodiment, and will not be repeated here.

[0124] In summary, the device provided in the embodiment of the present disclosure can couple the start and stop of the carbon capture system with the filling problem of carbon dioxide by detecting the amount of carbon dioxide captured in the carbon dioxide storage tank and controlling the carbon dioxide compressor according to the current amount of carbon dioxide captured in the carbon dioxide storage tank and the carbon dioxide filling requirements, thereby achieving flexible and intelligent regulation, reducing equipment corrosion caused by carbon dioxide accumulation, and endangering personnel safety.
