Abstract
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.
