Novel structure hydrogenation reactor, design method and application thereof

Abstract

The invention relates to a novel structure hydrogenation reactor as well as a design method and application thereof. Two reactors are combined in a whole, so that the reaction materials can react formultiple times in the two reactors, simultaneously the light component is separated from the heavy component; under the action of a feeding distributor, the reaction material flow is in a fully-backmixing state, the material flow in the reactor is in a turbulent state, and thus material deposition and coking are avoided. The axial temperature difference of the material flow is less than 10 DEG C and the radial temperature difference is less than 0.5 DEG C, so that the temperature of the materials in the reactors is uniform, and the equipment materials are not prone to fatigue and damage. An inner reaction feeding distribution separator of the reactor is connected with an outer reactor barrel through a sliding sleeve, the inner reaction feeding distribution separator can adjust the upper and lower positions according to the generation rate of the light components, and the particles in the reaction materials are prevented from being adhered to the top of the outer reactor barrel. The reactor is further provided with a cold hydrogen inlet and a cold oil inlet, and the temperature in the reactor can be controlled. The reactor is also provided with an emptying pipeline, so that the temperature runaway situation of the reactor can be treated in time.

Description

technical field [0001] The invention relates to a novel structural hydrogenation reactor and its design method and application, belonging to the fields of petroleum refining, chemical industry and coal chemical industry. Background technique [0002] As crude oil becomes heavier and inferior and people's requirements for refined oil become lighter and cleaner, more and more attention has been paid to the hydrogenation process of heavy oil and mixed oil-coal hydrogenation process. The coming heavy oil hydrogenation reaction equipment and reaction technology are also emerging in an endless stream. Most of the existing reactors are single reactors, or multiple reactors are used in series, which leads to the bulky structure of the reactor itself, and insufficient reaction of the reaction materials in the reactor. The flow state of materials in the reactor is difficult to control, and material deposition and coking are easy to occur. It is also difficult to control the temperat...

AI Technical Summary

Problems solved by technology

Most of the existing reactors are single reactors, or multiple reactors are used in series, which leads to the large structure of the reactor itself, and the reaction of the reaction materials in the reactor is insufficient.

The flow state of the material in the reactor is difficult to control, and it is easy to cause material deposition and coking

It is also difficult to control the temperature of the material in the reactor. The radial and axial temperature differences of the material are large, which makes the temperature distribution in the equipment uneven, and it is easy to generate temperature jumps. The long-term uneven temperature distribution also causes the reactor itself to be easily fatigued and damaged.
