Hydrogenation reactor with flush plate on the top

Abstract

The invention discloses a hydrogenation reactor with an impact-relief plate arranged on the top. The hydrogenation reactor of the present invention includes a material inlet pipe, an inlet diffuser, an upper head of the reactor, a sleeve-type flush reducing and equalizing plate, a catalyst bed, a catalyst support grid, a reactor cylinder, and a lower head of the reactor. , outlet collector, material outlet pipe and unloading pipe. The sleeve-type anti-shock equalizer includes a tray and a number of chimney distributors vertically arranged on the tray; the chimney distributor includes a downcomer and a downcomer arranged at the upper end of the downcomer ; The flanged spray tray includes a tray and several chimney distributors vertically arranged on the tray; the chimney distributor includes a downcomer and a wing plate arranged on the top of the downcomer. The hydrogenation reactor of the present invention is suitable for all hydrogenation reaction processes, especially hydrofinishing or hydrocracking processes with relatively large reactor scales.

Description

technical field [0001] The invention relates to a hydrogenation reactor, which belongs to the field of chemical equipment. The hydrogenation reactor of the present invention is suitable for all hydrogenation reaction processes, especially hydrofinishing or hydrocracking processes with relatively large reactor scales. 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 one of the technical means to produce clean fuels, hydrogenation technology plays 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 reactor performance. In th...

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
