ABSTRACT:
A reaction chamber (4) elongated along an essentially vertical axis in which at least one reaction fluid is circulated from top to bottom of said chamber (4) through at least one catalyst bed (5), whereby downstream from catalyst bed (5) in the direction of circulation of the reaction fluid, the chamber contains at least one inlet (1) for introducing at least one quenching fluid into contact with the reaction fluid, and downstream from inlet (1) the chamber contains at least one box (8) for further contact, mixing and quenching of said fluids. The box (8) has at least one passage section (9) for entry of the fluids into the box (8). Downstream from the passage section (9) the box (8) contains elements (11) that puts fluids into vortex motion in the box (8) in a direction essentially non-radial and non-parallel to the axis of the chamber.
