MIXING AND DISTRIBUTING DEVICE WITH MIXING AND EXCHANGE ZONES Russian patent published in 2019 - IPC B01J8/04 

FIELD: chemistry.

SUBSTANCE: invention relates to exothermic reactions and more specifically to hydrotreating, hydrodesulphurisation, hydrodenitrogenation, hydrocracking, hydrogenation, hydrodeoxygenation or hydrodearomatisation performed in a fixed bed reactor, more specifically, to a device for mixing and distribution of fluids in a reactor with a parallel downflow and to its use for exothermic reactions. Device for mixing and distribution of fluids for catalytic reactor with downflow includes at least one storage area, at least one mixing zone, comprising at least one shell for mixing fluids, at least one distribution zone, the mixing zone is located at the same level as the distribution zone, and also comprises at least one shell for fluid exchange, connected and communicating with said mixing shell, said exchange shell comprising at least one section of transverse channels suitable for passage of fluids from said exchange shell into said distribution zone.

EFFECT: invention provides a mixing device and a distribution device for fluids, which occupy a small space when placed in a catalytic reactor, and provide good efficiency for mixing fluids, good temperature uniformity and good distribution.
