Transfer apparatus comprising a vessel having an inlet and an outlet for particulate solid material and a inlet and outlet for fluid to flow in countercurrent or cocurrent to the solid material, and a packing within the vessel, the packing including a plurality of layers of bars (60 to 68) extending generally horizontally across the vessel, the bars of each layer being substantially parallel to one another and having a spacing between adjacent bars which is substantially the same for the bars of said layer. The parallel bars of each layer extend transversely, preferably perpendicular, to the parallel bars of the adjacent layer of layers. |
