The present invention consists of a device for distributing and collecting fluids at the outlet from an upstream granular bed in a multistage column having a plurality of granular beds, said device comprising a deflector, which can equalize the trajectories of the fluid stream lines from the outlet from the mixing chamber to the downstream bed of granular solid.
摘要:
A compact device for mixing fluids in a downflow reactor comprising at least one substantially horizontal gathering device provided with a vertical gathering line intended to receive the fluids, at least one injection device arranged in the gathering line, an annular mixing chamber located downstream from the gathering means in the direction of circulation of the fluids, the mixing chamber comprising an inlet end directly connected to the gathering line and an outlet end for passage of the fluids, and a horizontal predistribution plate comprising at least one chimney, the plate being located downstream from the mixing chamber at a distance d2, in the direction of circulation of the fluids. The reactor is especially useful for exothermic reactions, e.g. hydrotreatment, hydrodesulfurization, hydrodenitrogenation, hydrocracking, hydrogenation and hydrodearomatization reactions.

摘要:
Device and application thereof for distributing a multiphase mixture having at least one gas phase including, e.g., hydrogen in part and at least one liquid phase, the mixture being in a downward flow through at least one bed of granular solids, the device including, at least one distributor plate located above one of the beds of granular solids at a distance "d", and several mixing channels of the liquid and gas phases of the mixture. Each of the channels has at least one upper passage section and at least one lower passage section allowing communication between the mixture formed in the mixing channels with a bed of granular solids. The mixing channels are provided on at least part of their height with one or more lateral passage sections, the upper passage section allowing the majority of the gas phase of the mixture to pass and the lateral passage sections allowing passage of the liquid phase and/or at least part of the gas phase inside the mixing channels. The density value of the mixing channels is greater than 80 channels per square meter.
摘要:
An enclosure includes at least one packed bed and a mixture supply line for delivering at the bottom of the enclosure a mixture of a liquid with a gas. The enclosure includes a system for separating the liquid phase and the gas phase of the mixture, the system being arranged between the bed and the mixture supply line, and this system including a housing having a flow passage for the degassed liquid and discharge passages for the disengaged gas.
