Description

Technical Field

[0001] The present disclosure relates to the field of carbon capture technology, and in particular to a start-stop-canned 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 passed to the subsequent carbon dioxide compressor. For small 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, and there is a possibility of carbon dioxide poisoning to surrounding personnel. In addition, the high concentration of carbon dioxide staying in the pipeline for a long time will cause corrosion to the equipment, affecting the long-term use of the system.

[0046] The following describes in detail embodiments of the present disclosure, examples of which 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 coupled start-stop and tank-loading of CO2 capture, as provided in an embodiment of the present disclosure. This method can be implemented using a computer program and run on a device that performs coupled start-stop and tank-loading of CO2 capture. This computer program can be integrated into an application or run as a standalone tool application.

[0049] The CO2 capture start-stop and tank coupling device may be an electronic device with a CO2 capture start-stop and tank coupling function. The electronic device may be applied to a carbon capture system, for example.

[0050] Among them, the start-stop and canning coupling method for capturing carbon dioxide can be executed by electronic equipment.

[0051] For example, the start-stop and tank-loading 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 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 requirement, the carbon dioxide compressor is controlled 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 employed 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 tanking 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 employed when the CO 2 compressor stops compressing the CO 2 escaping from the regeneration tower into the CO 2 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 from 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 based on the current amount of carbon dioxide captured in the carbon dioxide storage tank and the carbon dioxide filling requirements. This 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 reduce risks to personnel safety.

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

[0063] like Figure 2 As shown, the start-stop and tank-loading 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 based on the current operating time and mass flow rate;

[0069] It should be noted that when the regeneration tower is operating, the pressure and temperature of the carbon dioxide output from its carbon dioxide output port can be considered approximately constant. For example, the carbon dioxide output from the carbon dioxide output port can be maintained at 2 kPa and ~90°C. In other words, the mass flow rate of the carbon dioxide output from the carbon dioxide output port can be considered approximately constant. Therefore, the current amount of carbon dioxide captured 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 can be determined, for example, according to the following formula:

[0071] m=ST

[0072] Where m is the current carbon dioxide capture capacity, 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 capacity corresponding to the carbon dioxide storage tank;

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

[0075] In some embodiments, a carbon dioxide demand corresponding to the carbon capture system may be determined, and a rated carbon dioxide capture capacity corresponding to the carbon dioxide storage tank may be determined based on the carbon dioxide demand. For example, the rated carbon dioxide capture capacity 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] As an example, assuming a design pressure of 2.4 MPa and a temperature of -20°C, a variant of the ideal gas state equation can be used. Considering that liquid CO2 deviates less from ideal behavior under these conditions, the CO2 density in the CO2 tank is as follows:

[0078] ρ CO2 =P / Rt=1140 kilograms / cubic meter (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 CO2 storage tank can be calculated according to the rated CO2 capture capacity using 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 size of the carbon dioxide storage tank remains fixed and the demand for carbon dioxide changes, 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 capacity threshold according to the rated carbon dioxide capture capacity;

[0086] According to some embodiments, since 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 after the regeneration tower is in a non-operating state, 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 remaining in the pipeline for a long time, causing corrosion to the equipment, affecting the long-term use of the system.

[0087] In some embodiments, the CO2 capture threshold is not a fixed threshold. The CO2 capture threshold can be adjusted based on actual application scenarios, so long as the CO2 storage tank is nearly full but not completely filled with liquid CO2 at 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 requirement;

[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 capacity 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-operating 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 and regenerating carbon dioxide. The non-operating state of the regeneration tower can be controlled 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 the corrosion problems caused by accumulated carbon dioxide on equipment, 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 requirement;

[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 rate 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 CO2 compressor; determines the mass flow rate of CO2 output from the regeneration tower during the current operating time; and determines the current CO2 capture capacity in the CO2 storage tank based on the current operating time and mass flow rate. Therefore, the accuracy of determining the current CO2 capture capacity can be improved. Next, the rated CO2 capture capacity corresponding to the CO2 storage tank is determined; based on the rated CO2 capture capacity, a CO2 capture capacity threshold is determined. If the current CO2 capture capacity is not less than the CO2 capture capacity threshold, the current CO2 capture capacity meets the CO2 canning requirements; if the current CO2 capture capacity is less than the CO2 capture capacity threshold, the current CO2 capture capacity does not meet the CO2 canning requirements. Therefore, the accuracy of determining whether the current CO2 capture capacity meets the CO2 canning requirements can be improved. Finally, if the current carbon dioxide capture amount meets the carbon dioxide filling 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; 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 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 carbon dioxide filling problem can be coupled to achieve flexible and intelligent regulation, reduce equipment corrosion caused by carbon dioxide accumulation, and reduce personnel safety risks.

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

[0104] The control unit 302 is also used to control the carbon dioxide compressor to compress the carbon dioxide escaping from the regeneration tower into the carbon dioxide storage tank 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 until the carbon dioxide escaping from the regeneration tower does not meet the compression requirements.

[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 canning 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 canning requirements.

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

[0115] Determine the carbon dioxide demand corresponding to the carbon capture system;

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

[0117] Optionally, after the current carbon dioxide capture amount meets the carbon dioxide tanking requirement, the control unit 302 is further configured 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 configured to, until the carbon dioxide escaping from the regeneration tower does not meet the compression requirement, specifically:

[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 an operating state, and the mass flow rate threshold is less than the mass flow rate of carbon dioxide output when the regeneration tower is in an operating state.

[0121] Optionally, the control unit 302 is configured to, after the carbon dioxide escaping from the regeneration tower fails to meet the compression requirement, further be configured 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 embodiments of the present disclosure 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 filling problem of carbon dioxide, realize flexible and intelligent regulation, reduce equipment corrosion caused by carbon dioxide accumulation, and endanger personnel safety.
