Abstract (en)

[origin: WO2008027718A2] This liquid distributor functions to uniformly distribute a descending liquid stream across the tray for interaction with an ascending vapor stream. It has a feed pipe (6) which delivers the liquid stream to an underlying elongated trough (4). Liquid discharge holes (18) are positioned in the floor (12) of the trough (4). A perforated v-plate (20) positioned within the trough (4) so that liquid from the feed pipe (6) passes through the perforated v-plate (20) before encountering the floor (12) of the trough (4). When liquid passes through the perforated v-plate (20), the stream is divided into smaller streams of lower velocity, providing a more uniform overall flow rate of liquid passing through the trough (4). Liquid is then delivered from the discharge outlets (18) of the trough onto the upper surface of the tray (35) with a substantially uniform flow rate across the trough (4).
