ABSTRACT:
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.
