A sieve plate (2) for use in a structure in which direct contact may be effected between a gas and a liquid, the sieve plate having a plurality of channels (13, 14, 15) within the plate leading from one surface of the plate to an opposite surface of the plate, in which the channels are so shaped as to provide in the channel within the plate a weir (16) over which liquid must pass if it is to flow downwardly through the channel. Also, a structure comprising one or more such sieve plates. |
