A device for the descending flow of a hydrocarbon-containing liquid containing solid particles at the bottom of an item of equipment () and a process for the conversion of hydrocarbon-containing feedstocks implementing said device.

Device comprising lateral injections of liquid for limiting the phenomena of solid deposits in items of equipment with a conical bottom

The invention concerns a method for converting heavy hydrocarbon feedstocks of which at least 50% by weight boils at a temperature of at least 300&#xb0; C., and in particular vacuum residues. The feedstocks are subjected to a first step a) of deep hydroconversion, optionally followed by a step b) of separating a light fraction, and a heavy residual fraction is obtained from step b) of which at least 80% by weight has a boiling temperature of at least 250&#xb0; C. Said fraction from step b) or the effluent from step a) is then subjected to a second step c) of deep hydroconversion. The overall hourly space velocity for steps a) to c) is less than 0.1 h. The effluent from step c) is fractionated to separate a light fraction. The heavy fraction obtained, of which 80% by weight boils at a temperature of at least 300&#xb0; C., is sent to a deasphalting step e). The deasphalted fraction DAO is then preferably converted in a step f) chosen from ebullated bed hydroconversion, fluidised bed catalytic cracking and fixed bed hydrocracking.

A gas/solid separation system that can be applied to any type of FCC unit regenerators, consists of a device for separating solid particles contained in a gas stream coming from the regeneration zone of a fluid catalytic cracking (FCC) unit bounded by an inner envelope () of cylindrical shape centered about the vertical axis of the regeneration zone, and an outer envelope () that has one approximately horizontal wall (), followed by one curvilinear wall (), and one approximately vertical wall (), the set of said walls () covering the inner envelope () and forming a set of separation chambers () radially distributed around the inner envelope () in which the gas/solid suspension to be separated circulates. This system makes it possible to obtain, at the same time, very good separation efficiency while minimizing the pressure drop and only requiring a single downstream cyclone stage.
