Description

Technical Field

[0001] This invention belongs to the field of fuel supply system technology, and particularly relates to a fuel supply method for the renovation of aviation kerosene tank farms. Background Technology

[0002] Aviation kerosene is a petroleum product, a transparent liquid blended from straight-run fractions, hydrocracking and hydrorefining components, and necessary additives. In recent years, domestic refineries have introduced aviation kerosene units on a large scale, or increased aviation kerosene production through upgrades, expansions, and optimized operations.

[0003] Currently, the renovation and expansion of old oil tank areas are mostly carried out based on the production status of the tank area and the overlap between old and new facilities. This involves applying for tank shutdown time for renovation and expansion, proceeding step by step under the premise of construction without operation and operation without construction. However, some oil tank areas have heavy construction tasks and tight schedules. To meet the urgent requirements of tank expansion, the renovation of old oil tank areas needs to increase the oil supply capacity while maintaining uninterrupted oil supply. Furthermore, some oil tank areas have compact land use planning, resulting in overlap between old and new tank areas during renovation, and complex and unclear underground structures, making it impossible to complete the renovation of new tank areas in one go, thus failing to ensure continuous oil supply. In addition, aviation kerosene has high requirements for oil quality, requiring sedimentation in storage tanks before entering the operational tanks for supply, further increasing the difficulty of renovation.

[0004] Therefore, how to provide a temporary fuel supply method for the conversion of aviation kerosene tank farms is a technical problem that urgently needs to be solved. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a fuel supply method for the renovation of aviation kerosene tank farms. By setting up temporary pipelines to form temporary oil receiving and dispatching pipelines, the old facilities can be dismantled and the new facilities constructed without interrupting fuel supply, greatly improving the flexibility and efficiency of construction.

[0006] This invention provides a fuel supply method for the renovation of aviation kerosene tank farms, comprising the following steps:

[0007] Establish temporary oil receiving and dispatching pipelines: Set up a first storage oil tank and a usage oil tank at a location that meets the construction conditions, establish temporary oil receiving pipelines from the oil receiving and dispatching terminal to the first storage oil tank and from the first storage oil tank to the usage oil tank, and establish a temporary oil dispatching pipeline from the usage oil tank to the bottling station for temporary oil receiving and dispatching.

[0008] Connecting to old oil tanks: Install temporary connection pipelines to connect old oil tanks and used oil tanks to transport the oil stored in the old oil tanks to the used oil tanks;

[0009] Dismantle old facilities and begin laying formal oil receiving pipelines: dismantle old pipelines and old oil tanks, set up a second storage tank, and establish formal oil receiving pipelines from the oil receiving and dispatching terminal to the first and second storage tanks respectively. The formal oil receiving pipelines are connected in parallel with the temporary oil receiving pipelines at the oil receiving and dispatching terminal.

[0010] Dismantle the temporary oil receiving pipeline and establish a formal oil dispensing pipeline: Use the temporary oil receiving pipeline to store oil in the oil tanks in use. Once the oil storage volume meets the dispensing demand, dismantle the temporary oil receiving pipeline. Establish a formal oil dispensing pipeline from the oil tanks in use to the filling station. The formal oil dispensing pipeline is connected in parallel with the temporary oil dispensing pipeline at the filling station.

[0011] Dismantle the temporary oil delivery pipeline and improve the formal oil receiving and delivery pipeline.

[0012] This technical solution establishes temporary oil receiving and dispatching pipelines by setting up temporary pipelines, enabling the dismantling of old facilities and the construction of new facilities without interrupting oil supply, greatly improving the flexibility and efficiency of construction.

[0013] In some embodiments, multiple second storage tanks are provided. This technical solution can increase the overall storage capacity and better meet the oil supply demand.

[0014] In some embodiments, the step of establishing temporary oil receiving and dispatching pipelines further includes: establishing a first temporary pipeline to connect the oil receiving and dispatching terminal and the oil tank in use; simultaneously establishing a second temporary pipeline to connect the first storage tank and the first temporary pipeline; the first and second temporary pipelines intersect at a temporary interface; and establishing a third temporary pipeline to connect the oil tank in use and the bottling station. The first, second, and third temporary pipelines constitute the temporary oil receiving and dispatching pipelines. When receiving oil, the oil flows from the oil receiving and dispatching terminal through the first temporary pipeline to the temporary interface, then through the second temporary pipeline into the first storage tank for storage and sedimentation, and from the first storage tank through the second temporary pipeline to the temporary interface, and then through the first temporary pipeline into the oil tank in use. When dispatching oil, the oil flows from the oil tank in use through the third temporary pipeline to the bottling station. This technical solution, by establishing multiple temporary pipelines and temporary interfaces, achieves continuous and flexible oil receiving and dispatching operations during the reconstruction process, ensuring uninterrupted oil supply.

[0015] In some embodiments, the interface of the oil receiving and dispatching terminal is equipped with a first valve, which is connected to a first temporary pipeline; a first oil pump is installed between the temporary interface of the first temporary pipeline and the oil tank in use, and the first oil pump is used to pump oil from the first storage tank into the oil tank in use; a second valve is installed between the input end of the filling station and a third temporary pipeline, and a second oil pump is installed between the second valve and the filling station, and the second oil pump is used to pump oil from the oil tank in use to the filling station. This technical solution achieves precise control and efficient transportation of oil flow, ensuring the continuity and stability of the oil supply process.

[0016] In some embodiments, during the connection step of the old oil tank, a temporary connection pipeline is set between the third temporary pipeline and the old oil tank, simultaneously connecting the first and third temporary pipelines. When the oil in the old oil tank is ready for direct use, it is transported directly to the oil tank in use via the temporary connection pipeline and the third temporary pipeline. When the oil in the old oil tank cannot be directly used, it is transported to the first storage oil tank via the temporary connection pipeline, sequentially through the third temporary pipeline, the first temporary pipeline, and the second temporary pipeline. This technical solution, through the flexible setting of temporary connection pipelines, achieves efficient transportation and flexible handling of oil from old oil tanks, avoiding oil waste.

[0017] In some embodiments, the steps of dismantling the old facilities and beginning the laying of the formal oil receiving pipeline further include: establishing a first formal pipeline and a second formal pipeline, wherein one end of the first formal pipeline is connected to the oil receiving and dispatching terminal and is in parallel with a first temporary pipeline, and the other end is connected in series with the second formal pipeline, with the end of the second formal pipeline furthest from the first formal pipeline sealed off; and establishing a third formal pipeline connected in parallel with the first and second formal pipelines, respectively, for connecting the second formal pipeline to the first and second oil storage tanks. This technical solution achieves seamless connection and flexible conversion between the old and new pipelines, ensuring the continuity and stability of the oil supply system during the reconstruction process.

[0018] In some embodiments, the interface of the oil receiving and dispatching terminal is equipped with a third valve, which is connected in parallel with the first valve and connected to the first formal pipeline. This technical solution achieves dual control over oil flow, ensuring flexible switching of the oil supply path during the renovation process.

[0019] In some embodiments, the dismantling of temporary receiving pipelines and the establishment of permanent dispensing pipelines further include: dismantling the first and second temporary pipelines; establishing a fourth permanent pipeline connected in parallel, used for connecting the first permanent pipeline to the first and second storage tanks; establishing a fifth permanent pipeline, one end of which is sealed and the other end connected to the bottling station; establishing a sixth permanent pipeline, one end of which is connected to the usage tank and the other end intersecting with the fifth permanent pipeline; during dispensing, the oil arrives at the bottling station from the usage tank via the third temporary pipeline, or sequentially via the sixth and fifth permanent pipelines. This technical solution optimizes and flexibly converts the oil supply path, ensuring the continuity and stability of the oil supply system during the reconstruction process.

[0020] In some embodiments, a fourth valve is provided between the input end of the filling station and the fifth formal pipeline. The fourth valve is connected in parallel with the second valve and in series with the second oil pump. A third oil pump is provided between the first and second formal pipelines. The outlet end of the third oil pump is connected to the first formal pipeline. The third oil pump is used to pump oil from the first or second storage tank through the third and second formal pipelines to the first formal pipeline, and then through the fourth formal pipeline into the second or first storage tank, for oil transfer between the first and second storage tanks. This technical solution realizes flexible oil transfer and efficient transportation between different storage tanks, ensuring the continuity and stability of the oil supply process.

[0021] In some embodiments, dismantling the temporary oil delivery pipeline and improving the formal oil receiving and delivery pipelines specifically includes: dismantling the third temporary pipeline and establishing a seventh formal pipeline, with one end of the seventh formal pipeline sealed and the other end connected in parallel with the first formal pipeline to the second formal pipeline; establishing an eighth formal pipeline, with one end connected to the oil tank in use and the other end intersecting with the seventh formal pipeline; during oil receipt, the oil from the receiving and delivery terminal enters the first and second storage tanks via the first and fourth formal pipelines for storage and sedimentation, and the oil in the first or second storage tank sequentially enters the oil tank in use via the third, second, seventh, and eighth formal pipelines; during oil delivery, the oil from the oil tank in use sequentially reaches the bottling station via the sixth and fifth formal pipelines. This technical solution optimizes and flexibly converts the oil supply path, ensuring the continuity and stability of the oil supply system during the reconstruction process.

[0022] Based on the above scheme, the fuel supply method for the reconstruction of aviation kerosene tank areas in this embodiment of the invention establishes a first storage tank and a usage tank before stopping fuel supply to the old tank area. Then, temporary receiving and dispatching pipelines are formed by setting up temporary pipelines, which can replace the fuel supply guarantee of the old tank area and avoid fuel supply interruptions caused by construction. By connecting to the old tanks, it is ensured that the fuel in the old tanks can continue to be used, avoiding fuel waste. In summary, this embodiment can carry out the demolition of old facilities and the construction of new facilities without interrupting fuel supply, greatly improving the flexibility and efficiency of construction, and is particularly suitable for situations with tight schedules and heavy workloads. By dismantling temporary pipelines and laying new pipelines in stages, the formal receiving and dispatching pipelines are gradually improved, reducing the complexity and risks in the reconstruction process.

[0039] like Figure 1 As shown, in one embodiment of the fuel supply method for the reconstruction of aviation kerosene tank farms according to the present invention, the fuel supply method for the reconstruction of aviation kerosene tank farms includes the steps of establishing temporary receiving and dispatching pipelines, connecting to old tanks, dismantling old facilities and starting to lay out formal receiving pipelines, dismantling temporary receiving pipelines and establishing formal dispatching pipelines, and dismantling temporary dispatching pipelines and improving formal receiving and dispatching pipelines. The step of establishing temporary receiving and dispatching pipelines includes: setting up a first storage tank 102 and a usage tank 103 at a location that meets construction conditions; establishing temporary receiving pipelines from the receiving and dispatching terminal 101 to the first storage tank 102 and from the first storage tank 102 to the usage tank 103; and establishing a temporary dispatching pipeline from the usage tank 103 to the filling station 105 for temporary receiving and dispatching of fuel. The step of connecting to old tanks includes: The steps of setting up a temporary connection pipeline 204 to connect the old oil tank and the used oil tank 103 to transport the oil stored in the old oil tank to the used oil tank 103; dismantling the old facilities and starting to lay the formal oil receiving pipeline include: dismantling the old pipeline and the old oil tank, setting up a second storage oil tank 104, and establishing formal oil receiving pipelines from the oil receiving and dispatching terminal 101 to the first storage oil tank 102 and the second storage oil tank 104 respectively. The formal oil receiving pipeline is connected in parallel with the temporary oil receiving pipeline at the oil receiving and dispatching terminal 101; the steps of dismantling the temporary oil receiving pipeline and establishing the formal oil dispatching pipeline include: using the temporary oil receiving pipeline to store oil in the used oil tank 103, and dismantling the temporary oil receiving pipeline after the oil storage volume meets the oil dispatching demand; establishing a formal oil dispatching pipeline from the used oil tank 103 to the filling station 105. The formal oil dispatching pipeline is connected in parallel with the temporary oil dispatching pipeline at the filling station 105.

[0040] In the above illustrative embodiment, the fuel supply method for the reconstruction of the aviation kerosene tank area involves establishing a first storage tank 102 and a usage tank 103 before stopping fuel supply to the old tank area. Then, temporary receiving and dispatching pipelines are formed by setting up temporary pipelines, which can replace the fuel supply guarantee of the old tank area and avoid fuel supply interruptions caused by construction. By connecting to the old tanks, it is ensured that the fuel in the old tanks can continue to be used, avoiding fuel waste. In summary, this embodiment can carry out the demolition of old facilities and the construction of new facilities without interrupting fuel supply, greatly improving the flexibility and efficiency of construction, and is particularly suitable for situations with tight schedules and heavy workloads. By dismantling temporary pipelines and laying new pipelines in stages, the formal receiving and dispatching pipelines are gradually improved, reducing the complexity and risks in the reconstruction process.

[0041] In some embodiments, multiple second storage oil tanks 104 are provided. Providing multiple second storage oil tanks 104 can increase the overall storage capacity and better meet the oil supply demand; multiple storage oil tanks can be flexibly allocated and used according to actual needs, avoiding the impact on the overall oil supply when a single oil tank fails.

[0042] Furthermore, such as Figure 2 As shown, the steps for establishing temporary oil receiving and dispatching pipelines also include: establishing a first temporary pipeline 201 to connect the oil receiving and dispatching terminal 101 and the oil tank 103; simultaneously establishing a second temporary pipeline 202 to connect the first storage oil tank 102 and the first temporary pipeline 201; the first temporary pipeline 201 and the second temporary pipeline 202 intersect at a temporary interface; and establishing a third temporary pipeline 203 to connect the oil tank 103 and the filling station 105; the first temporary pipeline 201, the second temporary pipeline 202, and... The third temporary pipeline 203 constitutes a temporary oil receiving and dispatching pipeline. When receiving oil, the oil flows from the receiving and dispatching terminal 101 through the first temporary pipeline 201 to the temporary interface, then through the second temporary pipeline 202 into the first storage tank 102 for storage and sedimentation. From the first storage tank 102, the oil flows through the second temporary pipeline 202 to the temporary interface, and then through the first temporary pipeline 201 into the usage tank 103. When dispatching oil, the oil flows from the usage tank 103 through the third temporary pipeline 203 to the filling station 105. This embodiment, by establishing multiple temporary pipelines and temporary interfaces, achieves continuous and flexible oil receiving and dispatching operations during the reconstruction process, ensuring uninterrupted oil supply. It also optimizes the oil storage and sedimentation process, improving the reliability and efficiency of the oil supply.

[0043] In some embodiments, such as Figure 2As shown, the interface of the oil receiving terminal 101 is equipped with a first valve 301, which is connected to a first temporary pipeline 201. A first oil pump 401 is installed between the temporary interface of the first temporary pipeline 201 and the oil tank 103, and the first oil pump 401 is used to pump oil from the first storage tank 102 into the oil tank 103. A second valve 302 is installed between the input end of the filling station and the third temporary pipeline 203, and a second oil pump 402 is installed between the second valve 302 and the filling station, and the second oil pump 402 is used to pump oil from the oil tank 103 to the filling station. This embodiment, through the configuration of the first valve 301, the first oil pump 401, the second valve 302, and the second oil pump 402, achieves precise control and efficient delivery of oil flow, ensuring the continuity and stability of the oil supply process, while improving the operational flexibility and safety of the system.

[0044] In some embodiments, such as Figure 3 As shown, in the step of connecting to the old oil tank, the temporary connection pipeline 204 is set between the third temporary pipeline 203 and the old oil tank, and simultaneously connects the first temporary pipeline 201 and the third temporary pipeline 203. When the oil in the old oil tank can be directly dispensed and used, it is directly transported to the oil tank 103 via the temporary connection pipeline 204 and the third temporary pipeline 203. When the oil in the old oil tank cannot be directly dispensed and used, it is transported to the first storage oil tank 102 via the temporary connection pipeline 204, the third temporary pipeline 203, the first temporary pipeline 201, and the second temporary pipeline 202. This embodiment achieves efficient transportation and flexible handling of oil from the old oil tank by flexibly setting the temporary connection pipeline 204, avoiding oil waste.

[0045] In some embodiments, such as Figure 3 As shown, a fifth valve 305 is installed between the temporary connection pipeline 204 and the old oil tank. When the oil stored in the old oil tank is transported to the oil tank 103, the fifth valve 305 is opened. A sixth valve 306 is installed between the first temporary pipeline 201 and the third temporary pipeline 203. When the oil in the old oil tank cannot be directly dispensed for use, the sixth valve 306 is opened. This embodiment, by setting the fifth valve 305 and the sixth valve 306, achieves flexible control over the oil transportation path of the old oil tank, ensuring effective management of oil flow under different circumstances, thereby improving the operational flexibility and safety of the oil supply system.

[0046] In some embodiments, such as Figure 4As shown, the steps of dismantling the old facilities and starting the laying of the formal oil receiving pipeline also include: establishing a first formal pipeline 501 and a second formal pipeline 502, wherein one end of the first formal pipeline 501 is connected to the oil receiving and dispatching terminal 101 and is connected in parallel with the first temporary pipeline 201, and the other end is connected in series with the second formal pipeline 502, with the end of the second formal pipeline 502 away from the first formal pipeline 501 sealed off; and establishing a third formal pipeline 503 connected in parallel, which is used to connect the second formal pipeline 502 with the first storage tank 102 and the second storage tank 104, respectively. This embodiment achieves seamless connection and flexible conversion between the old and new pipelines by establishing parallel and series formal pipelines, ensuring the continuity and stability of the oil supply system during the reconstruction process, while optimizing the oil transportation path and improving the overall oil supply efficiency.

[0047] In some embodiments, such as Figure 4 As shown, the interface of the oil receiving and dispatching terminal 101 is equipped with a third valve 303, which is connected in parallel with the first valve 301 and is connected to the first formal pipeline 501. This embodiment achieves dual control of oil flow by setting the third valve 303 in parallel with the first valve 301, ensuring flexible switching of the oil supply path during the renovation process, thereby improving the reliability and operational flexibility of the oil supply system. It should be noted that the third valve 303 and the first valve 301 should be installed simultaneously to facilitate the subsequent installation of the first formal pipeline 501.

[0048] In some embodiments, such as Figure 5 As shown, the dismantling of temporary oil receiving pipelines and the establishment of formal oil dispensing pipelines also include: dismantling the first temporary pipeline 201 and the second temporary pipeline 202; establishing a fourth formal pipeline 504 connected in parallel, which is used to connect the first formal pipeline 501 to the first storage tank 102 and the second storage tank 104 respectively; establishing a fifth formal pipeline 505, one end of which is sealed and the other end is connected to the filling station 105; establishing a sixth formal pipeline 506, one end of which is connected to the use tank 103 and the other end intersects with the fifth formal pipeline 505; when dispensing oil, the oil products arrive at the filling station 105 from the use tank 103 via the third temporary pipeline 203, or sequentially via the sixth formal pipeline 506 and the fifth formal pipeline 505. This embodiment optimizes and flexibly converts the oil supply path by removing temporary pipelines and establishing parallel and series formal pipelines, ensuring the continuity and stability of the oil supply system during the reconstruction process, while improving the overall oil supply efficiency and safety.

[0049] In some embodiments, such as Figure 5As shown, a fourth valve 304 is installed between the input end of the filling station and the fifth formal pipeline 505. The fourth valve 304 is connected in parallel with the second valve 302 and in series with the second oil pump 402. A third oil pump 403 is installed between the first formal pipeline 501 and the second formal pipeline 502. The outlet end of the third oil pump 403 is connected to the first formal pipeline 501. The third oil pump 403 is used to pump oil from the first storage tank 102 or the second storage tank 104 through the third formal pipeline 503 and the second formal pipeline 502 to the first formal pipeline 501, and then through the fourth formal pipeline 504 into the second storage tank 104 or the first storage tank 102, for oil transfer between the first storage tank 102 and the second storage tank 104. This embodiment, by setting the fourth valve 304 and the third oil pump 403, realizes flexible oil transfer and efficient transportation between different storage tanks, ensuring the continuity and stability of the oil supply process, while improving the operational flexibility and safety of the system.

[0050] It should be noted that the third oil pump 403 can also be used to pump oil from the first storage tank 102 or the second storage tank 104 to the first formal pipeline 501 via the third formal pipeline 503 and the second formal pipeline 502, and then to the receiving and dispatching terminal 101 for oil dispatching. This embodiment utilizes the third oil pump 403 to pump oil from the storage tanks to the receiving and dispatching terminal 101 via the formal pipelines, achieving flexible oil dispatching operations, ensuring the continuity and efficiency of the oil supply process, and improving the operational flexibility and reliability of the system.

[0051] In some embodiments, such as Figure 6 As shown, the dismantling of the temporary oil delivery pipeline and the improvement of the formal oil receiving and delivery pipeline specifically includes: dismantling the third temporary pipeline 203, establishing the seventh formal pipeline 507, sealing one end of the seventh formal pipeline 507, and connecting the other end in parallel with the first formal pipeline 501 to the second formal pipeline 502; establishing the eighth formal pipeline 508, connecting one end of the eighth formal pipeline 508 to the oil tank 103, and intersecting the seventh formal pipeline 507 at the other end; when receiving oil, the oil is transported from the receiving and delivery terminal 101 through the first formal pipeline... Pipeline 501 and the fourth formal pipeline 504 enter the first storage tank 102 and the second storage tank 104 for storage and sedimentation. The oil in the first storage tank 102 or the second storage tank 104 sequentially enters the usage tank 103 via the third formal pipeline 503, the second formal pipeline 502, the seventh formal pipeline 507, and the eighth formal pipeline 508. When dispensing oil, the oil from the usage tank 103 sequentially enters the bottling station 105 via the sixth formal pipeline 506 and the fifth formal pipeline 505. This embodiment optimizes and flexibly converts the oil supply path by dismantling the temporary oil dispensing pipeline and establishing parallel and series formal pipelines, ensuring the continuity and stability of the oil supply system during the reconstruction process, while improving the overall oil supply efficiency and safety.
