    Abstract: For a vertically disposed liquid-liquid contact column using spaced perforated trays of the ''''rain deck'''' type, an improved tray construction that has weir means on each deck to provide a liquid coverage at each deck and, in turn, insure uniform droplet flow from all the holes through each deck, as well as curtain means on the opposing side of each tray to preclude the countercurrently flowing liquid stream from immediately sweeping droplets from the downstream face of each perforated deck and causing an undesirable back-mixing effect. A preferred design also uses specially located nonperforated areas on each tray section to permit a solvent liquid, or other contact liquid, a chance to settle and minimize entrainment.
