Abstract
A vessel for the downflow of a preferably hydrocarbon liquid, containing solid particles: a bottom comprising a cylindrical upper part (11), a lower part (12) with a decreasing cross section and a varying angle of inclination α with respect to the vertical axis (Z), and an outlet pipe (9); injections (5) and (6) of recirculated and/or of makeup liquid into the lower and upper parts respectively; injections (5) inclined with respect to the tangent to the wall of the lower part at the injection point by an angle β1 in the vertical plane (xz) and by an angle β2 in the horizontal plane (xy); injections (6) are inclined with respect to the wall of the upper part by an angle θ1 in the vertical plane (xz) and by an angle θ2 in the horizontal plane (xy).
