Hydrogenation-reactor inner-guide technology and design method and application thereof

Abstract

The invention relates to a hydrogenation-reactor inner-guide technology and a design method and application thereof. A hydrogenation reactor comprises a reactor cylinder, wherein the reactor cylindercomprises a reactor head and a reactor body; an guide ring is installed at the upper portion of the inner wall of the reactor body; a reactor discharging pipe, a guide pipe distributor and a guide pipe are medially installed inside the reactor cylinder from top to bottom in sequence; the guide pipe distributor is in a hopper shape; one end of the guide ring fits the inner wall of the reactor cylinder, and the other end of the guide ring is of an annular structure protruding to the center of the reactor cylinder. According to the hydrogenation-reactor inner-guide technology and the design method and application thereof, reaction materials conducting ascending motion in the reactor are guided to the guide pipe distributor through the guide ring, the medium flowing direction is put in order,non-effective flowing is reduced, flowing efficiency is improved, energy consumption is reduced, and the light-component splitting rate is decreased; the coking probability of heavy components on theguide pipe wall and a light-component outlet is decreased; the medium flow length in the reactor cylinder is prolonged, an air cushion layer at the upper end of the reactor cylinder is shortened, thetemperature in the reactor cylinder is more even, and running efficiency is improved.

Description

technical field [0001] The invention relates to a process related to an internal diversion hydrogenation reactor, which belongs to the fields of oil refining, chemical industry and coal chemical industry. Background technique [0002] The gas-liquid or gas-liquid-solid three-phase hydrogenation reactor can handle heavy oil with high sulfur nitrogen, high heavy metal and high asphaltene content, and can also process oil-coal mixture. It has the characteristics of high light oil yield and environmental protection. Favored by people, it has gradually become the key research object of heavy oil processing, direct coal liquefaction and oil-coal co-refining process in recent years, and it will also become the most important reactor for refining hydrogenation process. [0003] At present, when dealing with heavy and low-quality oil or oil-coal mixture, in order to deeply hydrogenate the reaction raw materials, higher temperature and pressure are often used, and a lower space veloci...
