Problems solved by technology

[0003] In order to further improve the transportation efficiency of crude oil pipelines, the methods currently used are mainly to add pour point depressants, drag reducers, anti-wax precipitation agents, etc. Composed of complex chemical components, the cost is high, but the drag reduction effect on crude oil is relatively general
Moreover, with the progress of the transportation process, the temperature of crude oil continues to decrease and the viscosity continues to increase, which is easy to form wax on the crude oil pipeline, which in turn causes the energy consumption of crude oil transportation to increase continuously, and the cost of crude oil transportation continues to increase

Abstract

The invention discloses an efficient crude oil conveying process. The process specifically comprises the following steps: step 1, arranging a plurality of electromagnets above the outer side surface of a crude oil conveying pipeline at equal intervals, and connecting the electromagnets with a power supply through wires to obtain a magnetic suspension crude oil conveying pipeline; step 2, adding an aromatic hydrocarbon solvent into the crude oil, and performing mixing and stirring to obtain crude oil A; step 3, adding iron powder into the crude oil A, and performing mixing and stirring to obtain crude oil B; and (4) introducing the crude oil B into the magnetic suspension crude oil conveying pipeline, switching on the power supply for electrification, and adjusting the output voltage to enable the crude oil B to be conveyed in a suspension manner. According to the process, through the dual effects of magnetic suspension and the aromatic hydrocarbon solvent, the viscosity of crude oil can be greatly reduced, the pipeline conveying amount of the crude oil is increased, the conveying time of the crude oil in a pipeline is shortened, the energy consumption of a pump station, a heating furnace and a booster pump used in the crude oil conveying process is reduced, the comprehensive conveying cost of the crude oil is greatly reduced, and the economic benefit of users is improved.

Description

technical field [0001] The invention relates to the technical field of oil and gas storage and transportation, in particular to a high-efficiency crude oil transportation process. Background technique [0002] Most of the crude oil extracted from the oil field needs to be transported to a distant transshipment site or refinery through oil pipelines, during which pressure, heating, heat preservation and other transportation methods are required to maintain the fluidity of the crude oil. Due to the increasing dependence of the world economy on crude oil, the demand for crude oil is also increasing, and many crude oil pipelines have reached full capacity. [0003] In order to further improve the transportation efficiency of crude oil pipelines, the methods currently used are mainly to add pour point depressants, drag reducers, anti-wax precipitation agents, etc. Composed of complex chemical components, the cost is high, but the drag reduction effect on crude oil is relatively ...
