Patent ID: 8329974

Claim:
A method for filtration and distribution of a hydrocarbon feed containing plugging particles, comprising subjecting said feed in a hydrotreatment reactor, a selective hydrogenation reactor, or a reactor for conversion of residues or hydrocarbon cuts with a number of carbon atoms from 3 to 50, to a device filtering and distributing a gas phase and a liquid phase constituting the supply to a reactor comprising at least one fixed catalyst bed, said reactor functioning in a gas and liquid down-flow co-current mode, the liquid phase being charged with said plugging particles, said device comprising a tray located upstream of the fixed catalytic bed, said tray being constituted by a substantially horizontal base plane which is linked to the walls of the reactor and to which substantially vertical chimneys are fixed which are opened at their upper end to admit gas and at their lower end to evacuate the gas-liquid mixture for supplying the downstream catalytic bed, said chimneys being perforated over a certain fraction of their height by a continuous lateral slot or lateral orifices for the admission of liquid, said tray supporting a filtration bed surrounding the chimneys and said filtration bed being constituted by at least one layer of particles with a size which is less than or equal to the size of the particles of the catalytic bed.
