ABSTRACT:
A liquid-gas contact device comprising a liquid-gas contact tray comprising a multiplicity of the elongate apertures in the tray for the passage of gas from below to above the tray, each aperture having a gas deflector associated therewith in being so disposed as to impart to the gas a component of velocity in the general direction of liquid flow, and at least several liquid flow in impedance members arranged so as to control the liquid velocity on the liquid-bearing surface to prevent it from reaching so great a magnitude that the residence time of liquid on the tray is insufficient for adequate gas-liquid contact to take place. Preferably the tray comprises a sheet of expanded metal.
