Problems solved by technology

Solvent extraction is widely used in the oil industry. It is mainly based on the principle that the solubility of solutes in solvents is different. According to the principle of similar solubility, polar solutes can be dissolved in polar solvents, but non-polar The solute can be dissolved in a non-polar solvent, but the operation of the traditional oil extraction device is more complicated, and multi-stage extraction cannot be performed at the same time, and the oscillation effect of the extraction is not good, so that the extraction efficiency is greatly reduced

Abstract

The invention discloses a multistage extractor for separating saturated hydrocarbon and unsaturated hydrocarbon in an oil product, the multistage extractor comprises an extraction cylinder, the top of the extraction cylinder is connected with a connection drainage hopper communicated with the extraction cylinder, the top end of the connection drainage hopper is connected with a separation cylinder, and the central axes of the separation cylinder, the connection drainage hopper and the extraction cylinder coincide. And the top of the separation barrel is connected with a feeding pipe. According to the multi-stage extractor for separating the saturated hydrocarbon and the unsaturated hydrocarbon in the oil product, an oil product raw material and an extraction agent are conveyed into the separation barrel through the feeding pipe and are mixed for a period of time in the separation barrel, then the control valve is opened, and a mixed solution flows into the extraction barrel through the linkage drainage hopper and stands for a period of time until the mixed solution is layered; upper-layer liquid flows into the saturated hydrocarbon container through the first extraction pipe, after a proper amount of the upper-layer liquid flows into the saturated hydrocarbon container, liquid at the lower end in the saturated hydrocarbon container is conveyed into the extraction barrel through the circulating pumping pipe a, it is avoided that middle-layer liquid is doped in the saturated hydrocarbon container, and the extraction accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of extraction and separation of oil products, in particular to a multi-stage extractor for separating saturated hydrocarbons and unsaturated hydrocarbons in oil products. Background technique [0002] The traditional processing technology is to hydrorefine FCC gasoline to produce gasoline products that meet the national and industrial standards. To meet clean gasoline specifications, olefins need to be drastically reduced. Olefins are an important source of octane number in FCC gasoline, and a substantial reduction in olefin content will lead to a significant decrease in octane number in FCC gasoline. According to the characteristics of my country's FCC gasoline composition, in the process of FCC gasoline hydrodesulfurization / olefin reduction, some olefins are converted into various types of aromatic hydrocarbons and isomers with side chains through alkylation, aromatization, isomerization and other reactio...
