New hydrogen and circulating hydrogen compressor

Abstract

The invention belongs to the technical field of petrochemical hydrogenation, and particularly relates to a new hydrogen and circulating hydrogen compressor which comprises a compressor main machine (16), a separator (2), a circulating hydrogen separator (8), a loop cooler (6), a circulating hydrogen inlet cooling device (7), a new hydrogen primary compression pressure container (4), a circulatinghydrogen left primary compression pressure container (10) and a circulating hydrogen right primary compression pressure container (11). An outlet of the new hydrogen primary compression pressure container (4) is divided into two paths, an outlet of the circulating hydrogen separator (8) is divided into two paths, one path communicates with an inlet of the circulating hydrogen left primary compression pressure container (10), and the other path communicates with the circulating hydrogen right primary compression pressure container (11). The new hydrogen and circulating hydrogen compressor is compressor system equipment capable of treating new hydrogen and circulating hydrogen at the same time, has high reactor conversion rate and can stably and continuously operate for a long period.

Description

Technical field [0001] The invention belongs to the technical field of petrochemical hydrogenation, and particularly relates to a new hydrogen circulating hydrogen compressor. Background technique [0002] Vacuum residue is the heaviest remaining component of crude oil after atmospheric and vacuum distillation. It is solid at room temperature and can be used as raw materials for coking, catalytic, hydrogenation of residue, solvent deasphalting, viscosity reduction and other raw materials according to different properties. Among them, vacuum residue as fuel oil needs to meet certain quality standards, such as sulfur content and ash content. In petroleum refineries, residual oil is often used to process petroleum coke, residual lubricating oil, petroleum pitch and other products, or as a raw material for cracking. In petrochemical production, residual oil can be used to produce synthesis gas or hydrogen through partial oxidation, or used as a raw material for ethylene production b...

AI Technical Summary

Problems solved by technology

[0003] The ultra-large reciprocating compressor is the heart of the residual oil hydrogenation unit. Once the hydrogen compressor is shut down, the quenching hydrogen in the reactor bed will be interrupted, which will cause the catalyst bed to overheat and damage the equipment.

In order to prevent the occurrence of the above results, the measures often taken are emergency shutdown, which not only causes serious economic losses, but also seriously affects the feed of heavy catalysts and the balance of raw materials in the whole plant.

[0004] At present, due to structural design defects, the circulating hydrogen compressors used in the market have problems such as short operation period, low hydrogenation efficiency of residual oil, hydrogenation exhaust volume and exhaust pressure can not meet the technical requirements, etc.
