Description

TECHNICAL FIELD

[0001] The utility model mainly relates to the technical field of crude oil transportation, specifically a flange type multi-point filling mixing device on a crude oil pipeline. BACKGROUND

[0002] Crude oil transportation refers to the process of transporting crude oil mined from an oil field to a refinery, a port or other storage and processing facilities, and is a key link connecting upstream mining and downstream processing in the oil industry chain. Crude oil transportation refers to pipeline transportation, railway transportation, waterway transportation and highway transportation. Pipeline transportation refers to transporting crude oil through a specially laid pipeline system, and has the advantages of large transportation capacity, strong continuity, low cost, safety and reliability, and is one of the main ways of crude oil transportation at present.

[0003] Sulfur-containing crude oil contains a large amount of sulfur-containing compounds such as mercaptans, sulfides and thiophenes. These sulfur-containing compounds have a strong polar sulfur atom in their molecular structure, and the intermolecular force is large, which increases the internal friction between crude oil molecules, thereby increasing the viscosity of the crude oil. In order to meet the requirements of desulfurization of crude oil, the desulfurizer is added in the pipeline online. In the process of transporting crude oil through the oil production pipeline, the appropriate position is selected according to the actual situation to add the desulfurizer. Generally, the desulfurizer is added at a certain node of the pipeline, and the desulfurization reaction is carried out by mixing the desulfurizer with the crude oil using the flow of the crude oil in the pipeline. However, the flow of the crude oil in the pipeline is not ideal uniform flow, and there is uneven distribution of flow rate. The flow state of the fluid is more complex, and phenomena such as vortex flow and backflow may occur, which may cause uneven distribution of the desulfurizer in the pipeline, and the concentration of the desulfurizer in some areas is too high, while the concentration in some areas is too low, affecting the overall effect of the desulfurization reaction.
