Abstract

The disclosure belongs to the technical field of crude benzol refining and provides a method for producing high boiling point solvent oil as a by-product by crude benzol refining. The method includes the following steps: first, preheating crude benzol and feeding crude benzol into a pre-distillation column to remove low boiling point compounds and heavy benzol; and performing a hydrorefining reaction, wherein the treated refined materials enter two rectifying columns to produce high purity benzene, high purity toluene and xylene and produce high boiling point solvent oil as a by-product. The method has the advantages of simple process, stable operation, low production cost, high recovery rate of aromatic hydrocarbons, no need to additionally arrange separating apparatuses such as the rectifying column, so that the economic benefit and the social benefit of an enterprise are increased.
