Fuel-type oil refining system and oil refining process

Abstract

The invention discloses a fuel-type oil refining system and an oil refining process. A new concept of mesoscale micro-interface chemical reaction and transfer process synergistic reinforcement is introduced into oil refining technology, a new oil refining technology taking online integration of heavy oil emulsifying bed hydrogenation and distillate oil emulsifying fixed bed hydrogenation as the core is developed, and has the advantages of strong raw material adaptability, short process flow, low investment and production cost, high energy efficiency and resource utilization rate, cleanness, environmental protection and the like. According to the process route and method disclosed by the invention, construction of catalytic cracking, hydrocracking, delayed coking, heavy oil hydrogenation pretreatment and other processing devices are not needed in future fuel-type oil refineries, innovation of the traditional oil refining technology is realized, and the market competitiveness of oil refineries is improved.

Description

technical field [0001] The invention belongs to the field of petrochemical industry and relates to a petroleum refining process, in particular to a fuel type refining system and the refining process. Background technique [0002] Petroleum refining industry can produce gasoline, kerosene, diesel, BTX, olefins and other fuels and chemical industry raw materials. It is one of the most important pillar industries of the national economy. It is related to the country's economic lifeline and energy security. development has an extremely important position and role. [0003] Refining technology has developed to today, and the overall is relatively mature. Normally, a traditional fuel-based refinery includes atmospheric / vacuum distillation unit, catalytic cracking unit (FCC), hydrocracking unit, delayed coking unit, catalytic reforming unit, hydrofining unit and other main processing units, if If the properties of the crude oil are relatively poor, it is also necessary to increas...

AI Technical Summary

Problems solved by technology

[0004] Although the current oil refining technology can meet the needs of petroleum processing, and the individual technologies in each link are relatively mature, there are generally the following three main problems, which will affect the market competitiveness and future development of the petroleum processing industry

First, with the improvement of environmental protection requirements and the continuous upgrading of oil quality, the refining process is getting longer and longer, resulting in higher investment and production costs; second, the world's crude oil is showing a trend of heavy and inferior quality, and Heavy oil catalytic cracking technology, heavy oil hydrogenation pretreatment technology and hydrocracking technology have strict restrictions on the properties of raw materials, such as metal impurity content, asphaltene content, residual carbon content and other indicators, which will become the key bottleneck for future development; the third is the refining process The catalytic cracking technology in China has high gas yield and relatively poor quality of liquid products, and the delayed coking technology has prominent problems such as waste of resources (producing a large amount of coke) and not being environmentally friendly.
