Embodiment Construction

[0022] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0023] Such as figure 1 Shown, a kind of combined process of producing fuel oil, aromatic oil, asphalt described in the present invention utilizes catalytic oil slurry raw material, produces fuel oil, aromatic oil, asphalt by visbreaking (thermal cracking)-vacuum distillation combined process, improves Catalyze the yield of light oil from slurry processing, increase the aromatic content of aromatic oil, and improve the quality of aromatic oil and asphalt products.

[0024] The specific process flow is as follows: the catalytic oil slurry or mixed raw material stored in the raw material tank 1 is transported to the buffer tank 3 by the pump 2, then sent to the heatin...

Abstract

A fuel oil, aromatic hydrocarbon oil and asphalt combined production process is as follows: catalytic oil slurry or a mixed raw material stored in a raw material tank is conveyed into a buffer tank by a pump, then sent to a heating furnace for heating, and then enters a visbreaking reactor for thermal cracking reaction, after the reaction, reaction products enter into a vacuum distillation tower for separation, solvent oil, and by-product gas, fuel oil, aromatic hydrocarbon oil, and asphalt are successively obtained in the top line, the side line and the tower bottom of the vacuum distillation tower, the solvent oil, the fuel oil, the aromatic hydrocarbon oil and the asphalt with high added value and high market demand can be produced, the comprehensive utilization efficiency of catalytic oil slurry can be improved; at the same time, the light oil yield of the catalytic oil slurry can be significantly increased, content the aromatic hydrocarbon oil can be significantly improved, asphalt product aromaticity can be improved, aromatic hydrocarbon oil and asphalt quality can be improved, the process is simple, the operation condition is easy to control, and large-scale production is easy to realize.

Description

technical field [0001] The invention belongs to the field of oil refining and petrochemical industry, and relates to oil refining, comprehensive utilization and in-depth processing of oil refining and chemical by-products, in particular to a combined process for producing fuel oil, aromatic oil and asphalt. Background technique [0002] The oil slurry produced in the catalytic cracking process of heavy oil accounts for about 5-10% of the processing capacity of the catalytic cracking unit. FCC oil slurry has high density, low hydrogen-to-carbon atomic ratio, high residual carbon value, high content of aromatics, and short side chain condensed ring aromatics account for more than 70% of the total aromatics. The catalytic oil slurry contains a small amount of catalyst microparticles, the content of which is generally about 500-1000ug / g, and the diameter of the microparticles is about 5μm. The operation of the heavy oil catalytic cracking unit can digest part of the oil slurry ...
