The present invention concerns a fluid distributor in a multistage column, each plate P of the column being divided into a certain number of panels Pa, and each panel Pa being equipped with a distributor of the invention, said distributor comprising:

Fluid distribution and collection system in a multistage column comprising a jet breaker

Device for stiffening the plates of a multi-stage column with a diameter of more than 2 meters, whereby each plate supports a particle bed and the flow of at least one fluid passes through it from top to bottom, whereby said device consists of a number of beams that are located under the plate in question, each beam having a lower surface that is shaped like a triangle.

System for stiffening the plates of a large-diameter multi-stage column

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 d, 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.

Compact device for mixing fluids in a downflow reactor

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.

System and method for distribution of fluid a multistage column

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.

Enclosure containing a granular bed and a distribution of a gas phase and of a liquid phase circulating in an ascending flow in this enclosure

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.

Plate for distributing a multiphase mixture through a catalytic bed

Disclosed is a single-phase fluid distributor-mixer-extractor for separating beds of granular solids used in chromatography. The distributor includes a device for adding or removing a secondary fluid. The distributor further includes at least one calibrated orifice having a geometry designed to create a sufficient pressure drop to confine fluid turbulence inside a mixing chamber.

Single-phase fluid distributor-mixer-extractor for beds of granular

The invention is a device for distributing a multiphase mixture having at least one gas phase and at least one liquid phase in which the mixture flows downwardly through at least one bed of granular solids. The device includes at least one distributor plate located above one of the at least one bed of granular solids at a distance 'd' defining a space with 'd' ranging from 0 to 5 cm., the distributor plate including a plurality of mixing channels in which the at least one liquid phase and the at least one gas phase of the mixture are mixed, each of the channels having at least one upper passage section and at least one lower passage section providing communication of the mixture formed in the mixing channels with the at least one bed of granular solids, the mixing channels being provided along at least part of a height thereof with at least one lateral passage section, and the upper passage section allowing a majority of the at least one gas phase of the mixture to pass and the at least one lateral passage section providing passage of the at least one liquid phase inside the mixing channels and/or at least part of the at least one gas phase, and wherein the distance 'd' of separation of the distributor plate from one of the at least one bed of granular solids reduces any fragmentation of the mixture inside the space.
