  • Patent number: 4378292
    Abstract: A fluid-solids contacting apparatus which is useful in simultaneously contacting several different liquid streams with different parts of a fixed bed of solid material is disclosed. The apparatus comprises an imperforate centerpipe mounted in an outer vessel with discoid layers of fluid distributor pans being suspended from the centerpipe and the vessel. A fluid may be added or withdrawn at any layer through horizontal conduits leading to annular distribution rings mounted on the centerpipe, with smaller pipes branching radially from the distribution rings to the individual distributor pans. Each distributor pan comprises an upper and lower horizontal particle retaining screen and two flat flow diversion plates which force the fluid to flow to a central mixing area between the plates and at which the smaller pipe connects with the distributor pans. The distributor pans thereby serve to mix and redistribute fluids flowing vertically through the apparatus.
