A substantially planar plate, suitable for use in a structure in which direct contact may be effected between a gas and a liquid, the plate comprising a frame part and at least one bridging part between opposite sides of the frame part, the bridging part dividing the plate into upper and lower cavities bounded by the frame part and the bridging part, and one or more apertures through the bridging part leading from the lower cavity to the upper cavity. The structure comprises one or more such plates and in use of the structure gas will pass upwardly through the structure and liquid downwardly through the structure. The structure has many uses, eg in the cooling of electrolytically produced chlorine gas.
