ABSTRACT:
A ceramic packing element is formed from a stack of ceramic plates having parallel ribs forming parallel grooves therebetween. The grooves are closed into channels by the surf ace of an opposed plate. The ribs may engage the end surfaces of ribs on an adjacent space or may be interleaved with the ribs of an opposed plate to form smaller channels. The plates are adhered to each other by firing a stack of plates in the green state or wrapping film or bands around a stack of pre-fired plates. The elements may be preassembled into larger units before placement in a column by wrapping metal bands around an assembly of elements.
