Abstract: A liquid distributor tray for a distillation column for distributing a descending liquid phase to be contacted with an ascending vapor phase within the distillation column. A tray is provided for collecting the descending liquid phase and has rows of apertures for downward passage of the descending liquid phase. Rows of vapor risers are located between the rows of apertures for a passage of the ascending vapor phase, and an upward direction through the tray. Rows of elongated liquid collectors are located above the rows of vapor risers and between the rows of apertures for collecting all or part of the descending liquid phase before the descending liquid phase reaches the tray. Rows of elongated liquid collectors provided with slots or openings are provided for collecting and then redistributing the descending liquid phase caught in the liquid collectors over a central region of the tray. Such redistribution prevents replication of maldistribution throughout the column.
