Description

Technical Field

[0002] Carbon dioxide is considered one of the main greenhouse gases causing global climate change. Currently, countries around the world are striving to reduce carbon dioxide emissions and exploring various methods to capture and reduce atmospheric carbon dioxide concentrations. One common method is carbon capture and storage (CCS) technology, which captures carbon dioxide from emission sources and then stores it in underground storage facilities. However, this method requires significant energy and resources and presents certain technical challenges and safety risks.

[0003] Carbon capture, utilization, and storage (CCUS) is an indispensable key technology for achieving carbon neutrality, and carbon dioxide pipeline transportation is a crucial part of this technology. During supercritical carbon dioxide pipeline transportation, when leaks occur or venting operations are performed, the strong throttling effect of carbon dioxide can cause localized low temperatures within the main pipe and venting pipe, generating dry ice that can clog the pipeline and make the steel pipe brittle. This leads to pipeline damage.

[0029] This embodiment provides a method for venting carbon dioxide to be sealed. Figure 2 This is a flowchart of a method for venting carbon dioxide to be sealed according to an embodiment of this application, as shown below. Figure 2 As shown, the process includes the following steps S202-S206:

[0030] Step S202: If there is a venting requirement in the sealing equipment, determine the venting operation to be performed on the sealing equipment according to the venting requirement, wherein the venting requirement includes at least: venting type and the amount of carbon dioxide to be sealed corresponding to the venting type; the venting type includes at least: main pipeline venting and temporary storage space venting.

[0031] Step S204: Based on the venting operation content, determine at least two shut-off valves to be closed on the main pipeline of the sealing equipment, and record the parameter information of the target substance transported in the main pipeline after the at least two shut-off valves to be closed are closed;

[0032] Step S206: Control the opening and closing size of the valve between the main pipeline and the venting riser according to the parameter information, so as to vent the carbon dioxide to be sealed in the main pipeline between the at least two shut-off valves to be closed.

[0033] The above steps, when there is a venting requirement in the storage equipment, determine the venting operation to be performed on the storage equipment based on the venting requirement. The venting requirement includes at least: the venting type and the corresponding release amount of carbon dioxide to be stored; the venting type includes at least: main pipeline venting and temporary storage space venting; based on the venting operation, determine at least two shut-off valves to be closed on the main pipeline of the storage equipment, and record the parameter information of the target substance transported in the main pipeline after the closure of at least two shut-off valves; control the opening and closing size of the valves between the main pipeline and the venting riser based on the parameter information to vent the carbon dioxide to be stored in the main pipeline between the at least two shut-off valves to be closed, using the above technical solution. This solves the problem of inefficiently controlling the venting process of supercritical carbon dioxide, which easily leads to pipeline losses. It improves the management level of venting carbon dioxide to be stored, helps ensure the safety and sustainability of underground carbon dioxide storage, and improves the response efficiency when pipeline anomalies occur or the managed entity requests venting.

[0034] In an exemplary embodiment, before controlling the valve opening and closing size between the main pipeline and the vent riser according to the parameter information to vent the carbon dioxide to be sealed in the main pipeline between the at least two shut-off valves to be closed, the method further includes: determining the preset venting time of the sealing device; calculating the target time for complete venting when the valve opening and closing size of the main pipeline does not change; and comparing the venting time with the target time to determine whether to adjust the release amount of the multiple vent valves on the vent riser.

[0035] In an exemplary embodiment, after comparing the venting duration with the target duration to determine whether to adjust the release amount of the multiple venting valves on the venting riser, the method further includes: if the target duration is greater than the venting duration, determining to adjust the release amount of the multiple venting valves on the venting riser; if the target duration is less than or equal to the venting duration, determining not to adjust the release amount of the multiple venting valves on the venting riser.

[0036] In an exemplary embodiment, when the target duration is greater than the venting duration, after determining the release amount of the multiple venting valves on the venting riser to be adjusted, the method further includes: determining the difference duration between the target duration and the venting duration, and determining the target release amount corresponding to the difference duration; obtaining the maximum opening degree of each venting valve among the multiple venting valves on the venting riser and the first opening degree of each venting valve; and determining the target number of venting valves that can be adjusted based on the first opening degree and the maximum opening degree.

[0037] In an exemplary embodiment, after obtaining the maximum opening degree of each vent valve among multiple vent valves on the vent riser and the first opening degree of each vent valve, the method further includes: if it is determined that the first opening degree is less than the maximum opening degree, identifying the current vent valve as an adjustable valve; calculating the adjustable opening degree corresponding to the adjustable valve, and calculating the target total amount of target material allowed to pass through the adjustable opening degree within the venting time; summing up the target total amounts corresponding to multiple adjustable valves to obtain the maximum adjustable amount of the vent riser; if the maximum adjustable amount is less than or equal to the target release amount, determining that the venting time of the main pipeline is controlled within the preset venting time by adjusting the vent valves.

[0038] It should be noted that during the adjustment of the vent valve, to avoid excessive opening and closing that would cause the pipe temperature to drop too low during venting and generate dry ice, in actual engineering, the fluid temperature in the main pipeline at a distance from the vent end is monitored. The vent valve opening is then automatically controlled based on the temperature drop during venting to slow down the rate of temperature decrease. Simultaneously, multiple valves are installed on the vent riser to support the safe release of carbon dioxide, improving overall venting efficiency.

[0039] In an exemplary embodiment, after controlling the opening and closing size of the valve between the main pipeline and the vent riser according to the parameter information to vent the carbon dioxide to be sealed in the main pipeline between the at least two shut-off valves, the process includes: determining the venting result of the carbon dioxide to be sealed in the main pipeline; sending the venting result and the current environmental information corresponding to the vent riser to the management object of the sealing equipment, and instructing the management object to monitor the concentration change of the target substance at the location of the vent riser after venting.

[0040] Obviously, the embodiments described above are only some embodiments of this application, and not all embodiments. To better understand the above method, the following description, in conjunction with embodiments, illustrates the process, but is not intended to limit the technical solutions of the embodiments of this application. Specifically:

[0041] This application provides an optional embodiment of a carbon dioxide venting method to address the problem of inefficient control of the supercritical carbon dioxide venting process, which easily leads to pipeline losses. This method ensures the safe execution of the supercritical carbon dioxide venting process through valve setting strategies for the venting column and adjustment strategies during release. Specifically, reducing the valve opening can prevent excessively low temperatures inside the pipe during venting.

[0042] Optionally, to improve accuracy in practical applications, the relationship between valve opening and the absence of dry ice formation in the pipeline can be determined through simulation under selected venting simulation conditions. For example, simulation can determine that the valve opening should be 13.5% to prevent dry ice formation, and the valve opening should be below 4.5% when the pipeline temperature is not lower than -30°C.

[0043] Furthermore, during the venting process of high-pressure carbon dioxide pipelines, the convective heat transfer intensity is low and the temperature drop is significant at a distance from the vent outlet. The initial temperature has a substantial impact on the temperature inside the pipe during the venting process; the lower the initial temperature, the lower the temperature inside the pipe during venting, and the greater the likelihood of dry ice formation. Therefore, in practical engineering, by monitoring the fluid temperature inside the main pipeline at a distance from the vent outlet, and automatically controlling the opening of the venting valve based on the temperature drop inside the pipe during venting, the rate of temperature drop during the venting process can be slowed down.

[0044] Furthermore, to ensure the safety of subsequent venting, a high-pressure carbon dioxide pipeline venting model can be established. Specifically, when a long-distance high-pressure carbon dioxide pipeline leaks or requires planned venting, the shut-off valve can be closed to vent or fill the pipeline section. For pipeline operation safety, the spacing between shut-off valves along a supercritical carbon dioxide pipeline generally does not exceed 15 km. Based on the setup of a certain supercritical carbon dioxide pipeline venting station, the main parameters of the venting model are selected, with the ambient temperature along the pipeline set at 0.5℃. The main pipeline is divided into 200 segments, with the starting point being a closed node and the ending point being a pressure node. Initial temperature and pressure are set along the pipeline, and the venting riser is located at the end of the main pipeline, establishing a high-pressure carbon dioxide pipeline venting model. Then, under actual venting requirements, four characteristic points are selected from the main pipeline for simulation analysis.

[0045] As an optional implementation, when the pipeline needs to be vented according to plan, the shut-off valves at both ends of the pipeline are first closed, and the venting valve is opened to begin venting. Therefore, when venting begins, the pipeline is already filled with a certain amount of high-pressure carbon dioxide. In the simulation, it is assumed that the venting valve opens instantaneously to the required opening degree from the start of venting and remains constant throughout the venting process. The initial pressure and temperature of the carbon dioxide in the main pipeline are directly related to the venting volume, while the venting valve opening degree affects the release rate. Therefore, both the venting volume and the venting valve opening degree affect the venting time and the temperature drop within the pipeline. Thus, it is necessary to set the initial temperature and pressure within the main pipeline. By changing the venting valve opening degree and the initial carbon dioxide pressure and temperature, the temperature, pressure, and phase changes at different nodes under different operating conditions can be obtained.

[0046] Furthermore, multiple valves can be installed on the aforementioned vent riser for flow control and pipe temperature adjustment. By using vent ports of different orifice sizes to quickly adjust the venting volume, the operating temperature within the pipe can be kept constant. Figure 3This is a schematic diagram of the structure of a venting riser according to an embodiment of this application.

[0047] In summary, the optional embodiments of this application, in actual engineering, monitor the fluid temperature in the main pipeline at a distance from the venting end, and automatically control the opening of the venting valve based on the temperature drop in the pipe during the venting process, thereby slowing down the rate of temperature drop during venting. Simultaneously, on the venting pipe side, multiple valves are installed on the venting riser to support the safe release of carbon dioxide, improving the overall venting efficiency. This solves the problem of inefficiently controlling the venting process of supercritical carbon dioxide, which easily leads to pipeline losses. It improves the management level of venting carbon dioxide to be sealed, helps ensure the safety and sustainability of underground carbon dioxide sealing, and enhances the response efficiency when pipeline anomalies occur or when the managed entity requests venting.

[0048] Through the above description of the embodiments, those skilled in the art can clearly understand that the methods according to the above embodiments can be implemented by means of software plus necessary general-purpose hardware platforms. Of course, they can also be implemented by hardware, but in many cases the former is a better implementation method.
