Description

Technical Field

[0001] The present invention belongs to the field of pipeline risk management and control, and specifically relates to a method for analyzing high-consequence areas of a pure hydrogen pipeline, a device for the method for analyzing high-consequence areas of a pure hydrogen pipeline, and a machine-readable storage medium. Background Art

[0002] The relevant specifications for long-distance hydrogen pipelines in my country are weak. The existing long-distance hydrogen pipelines are basically designed and constructed in accordance with the standards of oil and gas pipelines and industrial pipelines and foreign hydrogen pipeline standards, and the operation and management are basically carried out in accordance with the oil and gas long-distance pipeline model. The high consequence area is an important aspect of risk to ensure the safe operation of pure hydrogen pipelines. However, there are differences between the properties of hydrogen and the design of pure hydrogen pipelines and oil and gas pipelines. Hydrogen has a low density and a wide explosion limit, and the diameter of pure hydrogen pipelines is small and the transmission pressure is low. At present, there is no high consequence area analysis method for pure hydrogen pipelines, which seriously restricts the development of production operations and risk assessment disciplines. It is urgent to propose a high consequence area analysis method for pure hydrogen pipelines to ensure the safe operation of pure hydrogen pipelines and the development of the entire hydrogen energy industry chain.

[0003] CN 110070241A provides a management system and method for high consequence areas of oil and gas pipelines. The system comprises: a high consequence area management module, including: a high consequence area data management unit for receiving data of high consequence areas of pipelines sent by a client, and maintaining and updating the high consequence area data; a high consequence area identification management unit for processing the received data of high consequence areas of pipelines of the client according to certain preset rules, and identifying the high consequence areas; a high consequence area evaluation management unit for evaluating and grading the high consequence areas identified by the high consequence area identification management unit, and managing the grading results; a high consequence area management decision unit for making management decisions on the high consequence area identification results and grading results, specifying different high consequence area management measures, and improving the safety and economy of pipeline management.

[0004] CN108960049A discloses a method, device and storage medium for identifying high consequence areas of long-distance oil and gas pipelines, belonging to the technical field of risk assessment of long-distance oil and gas pipelines. The method comprises: obtaining a target remote sensing image composed of a pipeline area with the center line of the target pipeline as the axis of symmetry and a first distance threshold as the radius of symmetry, identifying multiple ground object categories in the target remote sensing image through a first classification recognition model to determine the areas where the multiple ground object categories are located, determining the ground object attribute information of the area where each ground object category in the multiple ground object categories is located according to the geographic information of the pipeline area in the target remote sensing image, and then identifying the high consequence area of ​​the target pipeline from the pipeline area in the multiple image areas. The present invention can determine the high consequence area of ​​the target pipeline by automatically identifying the target remote sensing image covering the target pipeline, thereby improving the recognition efficiency and accuracy of the high consequence area of ​​the long-distance oil and gas pipeline.

[0005] CN110070242A provides a system and method for identifying and evaluating high-consequence areas of gas transmission pipelines. The method comprises analyzing and processing the information in a pre-established database module to extract basic pipeline data and surrounding geographic information data; extracting consequence element information data related to the high-consequence area of ​​the pipeline from the basic pipeline data and the surrounding geographic information data according to a pre-set consequence element selection rule to form a consequence element set; using the data in the consequence element set to classify the area along the pipeline according to a pre-set regional grade assessment parameter to obtain regional grade data; identifying the consequence element set data and the regional grade data according to a pre-set gas transmission pipeline high-consequence area identification criterion to obtain a high-consequence area; and evaluating the severity of the consequences of the identified high-consequence area according to a pre-set gas transmission pipeline high-consequence area assessment criterion to improve the quality and efficiency of identification.

[0040] Figure 2 The present application provides a method for analyzing high-consequence areas of pure hydrogen pipelines, which is applicable to pure hydrogen pipelines currently in service buried underground. The method comprises:

[0041] S1. Obtaining environmental data of the current position of the target pipe section;

[0042] The environmental data includes the location of inflammable and explosive places and specific places near the target pipe section. Inflammable and explosive places include gas stations, oil depots, etc. Specific places refer to building areas where people are difficult to evacuate or areas where 30 or more people gather for at least 50 days in a year, such as hospitals, schools, nurseries, kindergartens, nursing homes, prisons, shopping malls, markets, temples, stadiums, squares, entertainment and leisure places, theaters, camping sites, etc.

[0043] In addition, the environmental data also includes the number of buildings directly above the target pipe section, such as the number of residential buildings.

[0044] S2, obtaining pipeline parameters of the target pipe section;

[0045] This embodiment mainly includes the outer diameter of the pipeline and the maximum allowable operating pressure of the pipe section.

[0046] S3. Determine the regional level of the area through which the target pipe section passes according to the environmental data;

[0047] For example, for buried pipelines, the regional level of the area through which the target pipeline passes can be determined based on the number of buildings directly above the target pipeline section. The details are as follows:

[0048] S301, determining whether the number of buildings directly above the target pipe section is not greater than a first threshold value, if so, the area through which the target pipe section passes is a Level I area;

[0049] S302. Otherwise, further determine whether the number of buildings directly above the target pipe section is not greater than a second threshold value. If so, the area through which the target pipe section passes is a Class II area; otherwise, the area through which the target pipe section passes is a Class III area; wherein the second threshold value is greater than the first threshold value.

[0050] Exemplarily, the first threshold may be 36, and the second threshold may be 66, as shown in the following Table 1:

[0051] Table 1 Regional classification criteria 1

[0052] Regional level Number of buildings Ⅰ 0～36 Ⅱ 37～66 Ⅲ 66 and above

[0053] S4. Calculating the potential influence radius on both sides of the target pipe section according to the pipeline parameters;

[0054] Specifically, the calculation formula for the potential influence radius r on both sides of the target pipe section is as follows:

[0055]

[0056] In the above formula (1), d is the outer diameter of the pipeline, in mm; p is the maximum allowable operating pressure of the pipe section, in MPa; and 0.47 is an empirical constant.

[0057] S5. Determine the high consequence area level of the target pipe segment based on the regional level and the potential impact radius; 1) If the potential impact radius on both sides of the target pipe segment is greater than a set value (200 meters in this embodiment); then determine the high consequence area level of the target pipe segment based on the regional level and the potential impact radius, including:

[0058] Determine whether the target pipe section passes through the Level III area. If so, the target pipe section belongs to the Level III high consequence area;

[0059] Otherwise, determine whether the target pipe section passes through the Level II area. If so, the target pipe section belongs to the Level II high consequence area;

[0060] Otherwise, determine whether there are flammable and explosive places within the potential impact radius on both sides of the target pipe section. If so, the target pipe section belongs to the Level II high consequence area;

[0061] Otherwise, determine whether there are specific places within the potential impact radius on both sides of the target pipe section. If so, the target pipe section belongs to the Level I high consequence area;

[0062] Otherwise, it belongs to the Level 0 high consequence area (also called the non-high consequence area).

[0063] 2) If the potential impact radius on both sides of the target pipe section is less than a set value (200 meters in this embodiment); the high consequence area level of the target pipe section is determined based on the area level and the potential impact radius, including:

[0064] Determine whether the target pipe section passes through the Level III area. If so, the target pipe section belongs to the Level III high consequence area;

[0065] Otherwise, determine whether the target pipe section passes through the Level II area. If so, the target pipe section belongs to the Level II high consequence area;

[0066] Otherwise, determine whether there are inflammable and explosive places within the set value range on both sides of the target pipe section. If so, the target pipe section belongs to the Class II high consequence area;

[0067] Otherwise, it is determined whether there is a specific location within the set value range on both sides of the target pipe section. If so, the target pipe section belongs to the Class I high consequence area;

[0068] Otherwise, it belongs to the Level 0 high consequence area (also called the non-high consequence area).

[0069] Combining the above two situations, the grading judgment process is as follows: Figure 3 shown.

[0070] Specifically, the classification of high consequence areas of the target pipe section can be referred to as shown in Table 2 below:

[0071] Table 2 Identification criteria for high consequence areas of pure hydrogen pipelines

[0072]

[0073] S6. Obtaining preset management measures based on the high consequence area level.

[0074] Exemplarily, if it is detected that the target pipe section does not belong to a high consequence area (or is a level 0 high consequence area), the current management status is maintained; if it is detected that the target pipe section belongs to a level I high consequence area, monitoring and surveillance equipment is added to the location of the target pipe section; if it is detected that the target pipe section belongs to a level II high consequence area, monitoring and surveillance equipment and fire-retardant and explosion-proof devices are added to the location of the target pipe section; if it is detected that the target pipe section belongs to a level III high consequence area, monitoring and surveillance equipment, fire-retardant and explosion-proof devices and the inspection frequency of the area where the target pipe section is located are increased.

[0075] It should be understood that although Figure 2 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. Moreover, Figure 2 At least part of the steps may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily executed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least part of the sub-steps or stages of other steps.

[0076] Example 2

[0077] The operating pressure of a pure hydrogen pipeline is 4MPa, and the outer diameter of the pipeline is 350mm. There is a school near the target pipeline that needs to be analyzed for high-consequence areas, the distance is 2km, and the number of buildings above the pipeline is 12. The following is a high-consequence area analysis of the pure hydrogen pipeline:

[0078] Referring to Table 1, the regional grade of the pure hydrogen pipeline is Grade I;

[0079] The potential impact radius is calculated according to formula (1), and the potential impact radius is 329 m. Since the school is 2 km away from the pipeline, there is no specific place within the potential impact radius.

[0080] Referring to Table 2, it can be seen that the pipeline passes through the Class I area and there are no specific places within the potential impact radius, so it does not belong to the high consequence area.

[0081] Example 3

[0082] The maximum allowable operating pressure of a pure hydrogen pipeline is 3.2MPa, and the outer diameter of the pipeline is 600mm. There is a hospital near the target pipeline that needs to be analyzed for high-consequence areas, 1.5km away, and the number of buildings directly above the pure hydrogen pipeline is 68. The following is a high-consequence area analysis of the pure hydrogen pipeline:

[0083] Referring to Table 1, the regional grade of the pure hydrogen pipeline is Grade III;

[0084] The potential impact radius is calculated according to formula (1), and the potential impact radius is 504m. The distance to the hospital is 1.5km, and there is no specific place within the potential impact radius.

[0085] Referring to Table 2, it can be seen that the pipeline passes through a Level III area and therefore belongs to a Level III high consequence area.
