A liquid distributor for use in a column having distillation trays has been developed. The liquid distributor functions to uniformly distribute a descending liquid stream across the tray for interaction with an ascending vapor stream. The liquid distributor has a feed pipe which delivers the liquid stream to an underlying elongated trough. Liquid discharge holes are positioned in the floor of the trough. A perforated v-plate positioned within the trough so that liquid from the feed pipe passes through the perforated v-plate before encountering the floor of the trough. When liquid passes through the perforated v-plate, the stream is divided into smaller streams of lower velocity, providing a more uniform overall flow rate of liquid passing through the trough. Liquid is then delivered from the discharge outlets of the trough onto the upper surface of the tray with a substantially uniform flow rate across the trough.
