Distribution device for producing a polyphase mixture, and associated reactor

A device for mixing two fluids and distributing said mixture, comprising a chamber (110) supplied with a liquid first fluid consisting essentially of hydrocarbons, said chamber being filled with said first fluid, and a series of tubes or conduits (108) traversing said chamber in a substantially vertical direction and supplied with an essentially gaseous second fluid consisting essentially of hydrogen, said tubes being perforated by lateral orifices distributed over a plurality of levels allowing said tubes to communicate with said chamber, said tubes having a diameter dc in the range 3 to 100 mm for a surface velocity of the first fluid in the range 0.1 to 100 cm/s, said tubes also having a distance of more than 50 mm between orifices located at the lowest level with respect to the direction of flow of the fluid or fluid mixture at the tube outlet, said device being located at the head of hydrocracking, hydrotreatment, hydrodesulphurization or C2 to C5 cut selective hydrogenation reactor.
