A hydrogenation reactor having an impact reducing assembly

Abstract

The invention discloses a hydrogenation reactor with an impact reducing assembly. The hydrogenation reactor comprises a material inlet pipe, an inlet diffuser, a reactor upper head, an annular plate type impact reducing and flow equalizing tray, a catalyst bed layer, a catalyst support grid, a reactor barrel, a reactor lower head, an outlet collector, a material outlet pipe and a catalyst discharging pipe. The annular plate type impact reducing and flow equalizing tray comprises a column tray and a distributor arranged on the column tray, the distributor is formed by arranging a plurality of layers of impact reducing annular plates on the column tray in a concentric circle mode, and a plurality of downcomers used for collecting and discharging materials are arranged between every two adjacent layers of the impact reducing annular plates. The hydrogenation reactor provided by the invention is suitable for a hydrogenation reaction process, especially for a hydrofining or hydrocracking process used for a raw material containing scale and utilizing a large-scale reactor.

Description

technical field [0001] The invention relates to a hydrogenation reactor with an impact reduction component, which belongs to the field of chemical equipment. The hydrogenation reactor of the invention is especially suitable for the hydrofinishing or hydrocracking process in which there are many scales in raw oil and the reactor scale is large. Background technique [0002] In recent years, with the rapid economic development and the enhancement of environmental protection awareness, the quality and environmental protection requirements of petrochemical products are getting higher and higher. As a technical means of producing clean fuels, hydrogenation technology is playing an increasingly important role in the oil refining industry. In the hydrogenation unit, like the hydrogenation catalyst technology and the hydrogenation process technology, the hydrogenation reactor technology is an important part of the reactor system, and the three constitute the three factors of the re...

AI Technical Summary

Problems solved by technology

Since the hydrogenation process is an exothermic reaction, the feedstock oil is unevenly distributed on the radial section of the catalyst bed, which will lead to different reaction degrees and radial temperature differences, and even local overheating, which will damage the performance of the catalyst and greatly reduce the catalyst performance. life cycle
