Description

Technical Field

[0001] The invention belongs to the technical field of oil supply systems, and in particular relates to an oil supply method for reconstruction of aviation kerosene tank areas. Background Art

[0002] Jet fuel is one of the petroleum products. It is a transparent liquid blended from straight-run fractions, hydrocracking and hydrofining components and necessary additives. In recent years, domestic refineries have introduced jet fuel units in large quantities, or increased jet fuel production through renovation, expansion, and optimized operation.

[0003] At present, the reconstruction and construction of old oil tank areas are mostly carried out according to the production status of the oil tank area and the intersection of new and old facilities, and the oil tanks are shut down for renovation and expansion. Under the premise of no operation during construction and no construction during operation, the reconstruction and expansion are carried out step by step. However, some oil tank areas have heavy construction tasks and tight construction periods. In order to meet the urgent task requirements of oil tank expansion, the reconstruction and construction of old oil tank areas need to expand the oil supply capacity while uninterrupted oil supply; and some oil tank areas have compact land planning, which will cause the intersection of new and old oil tank areas during reconstruction, and the underground hidden buildings are complex and unclear, making it impossible to complete the reconstruction of new oil tank areas in one go, and thus unable to form a continuous oil supply guarantee. In addition, aviation kerosene has high requirements for the quality of oil, and it needs to be precipitated in the storage tank before entering the use tank for oil supply, which further increases the difficulty of reconstruction.

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

[0005] In view of the shortcomings of the prior art, the present invention provides a fuel supply method for the reconstruction of a jet fuel tank area. By setting up a temporary pipeline to form a temporary oil sending and receiving pipeline, the old facilities can be dismantled and new facilities can be constructed without interrupting the fuel supply, thereby greatly improving the flexibility and efficiency of the construction.

[0006] The present invention provides a fuel supply method for reconstruction of a jet fuel tank area, comprising the following steps:

The formal oil receiving pipeline is connected in parallel with the temporary oil receiving pipeline at the oil receiving and dispatching terminal;

[0010] Dismantle the temporary oil receiving pipeline and establish a formal oil delivery pipeline: Use the temporary oil receiving pipeline to store oil in the oil tank in use.

[0022] Based on the above scheme, the fuel supply method for the reconstruction of the aviation kerosene tank area in the embodiment of the present invention can replace the fuel supply guarantee of the old tank area by first establishing a first storage tank and a use tank before stopping the fuel supply in the old tank area, and then forming a temporary oil receiving and sending pipeline by setting up a temporary pipeline, so as to avoid the interruption of fuel supply caused by construction; by connecting the old tank, it is ensured that the oil in the old tank can continue to be used, and the waste of oil can be avoided. In summary, this embodiment can carry out the demolition of old facilities and the construction of new facilities under the condition of uninterrupted fuel supply, which greatly improves the flexibility and efficiency of construction, and is particularly suitable for situations with tight construction period and heavy tasks; by dismantling temporary pipelines and laying new pipelines in stages, the formal oil receiving and sending pipelines are gradually improved, which reduces the complexity and risk of the reconstruction process.
