Hydrogenation reactor for petrochemical engineering

Abstract

The invention discloses a hydrogenation reactor for petrochemical engineering and belongs to the technical field of petrochemical engineering. An inlet distributor is fixed on an upper spherical cover, a catalyst entering the hydrogenation reactor is fully dispersed and diffused, full contact between crude oil and the catalyst is realized, the crude oil is fully cracked and decomposed in a refining device, and the effective utilization rate of the catalyst can be increased. An outlet collector is placed at the bottom of a lower spherical cover and can recycle the catalyst which is not fully utilized by the crude oil, effective utilization of the catalyst is further improved, the crude oil refining cost is reduced, and the crude oil refining benefits are increased. A longer thermocouple isreliably fixed on the inner wall of the hydrogenation reactor in an inner extension tube support manner, the structural strength of a thermocouple sleeve is improved, and bending or damage to the thermocouple sleeve during usage is avoided.

Description

technical field [0001] The invention relates to the technical field of petrochemical industry, in particular to a hydrogenation reactor for petroleum petrochemical industry. Background technique [0002] As we all know, the crude oil extracted from the ground needs to be refined before it can become various oils that can be used. Among them, oil refining is a process of distilling crude oil or other oils without changing the molecular structure. In the process of oil refining, crude oil must go through a series of processes to obtain various useful petroleum products. Generally refers to petroleum refining, that is, cracking crude oil into kerosene, gasoline, diesel, heavy oil and other fuels suitable for internal combustion engines, and producing chemical raw materials, such as olefins, aromatics, etc. The current refinery is generally an oil-chemical combination type refinery factory. [0003] In the refining process of petroleum, it is necessary to use a variety of refi...

AI Technical Summary

Problems solved by technology

After the crude oil and the catalyst enter the refinery equipment, if the crude oil and the catalyst cannot be fully mixed, it is impossible to ensure that the crude oil is fully cracked and decomposed inside the refinery equipment

At the same time, the crude oil reacts with the catalyst in the hydrogenation reactor to form a mixture of various oils and catalysts. The catalyst pellets in the hydrogenation reactor are not fully utilized by the crude oil during the reaction process. Mixing it with the resulting mixture of kerosene, gasoline, diesel, heavy oil and other fuels will cause a great waste of catalyst

[0004] Moreover, the thermocouple sleeve used for heating in the hydrogenation reactor in the prior art is installed on the cylinder wall of the reaction tank, but, because the intensity of the thermocouple sleeve is longer, thermoelectricity often occurs in the process of use. Phenomenon that the coupler casing is bent or damaged
