Ceramic Cross-Partition Ring is a packing designed basically from the Raschig Ring with the cross-partitions inside to increase the surface and enhance the transfer efficiency. It is usually used extensively for the supporting packing at the bottom of tower. In general, because this packing normally has very large size, it is applied as ceramic supports for random packings.
