<p>Transfer apparatus comprising a vessel (10, 12) having an inlet (14, 16) and a outlet (15, 18) for particulate solid material and an inlet (22, 26) and outlet (24, 28) for fluid to flow in countercurrent or cocurrent to the solid material, and a packing (30, 32) 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.</p> |
