Abstract
A gas-liquid contacting apparatus is provided wherein the perforated trays are divided into portions by a lattice-like pattern of downcomers which deliver liquid to central regions of the tray portions immediately below them. An odd number, X, for example three parallel downcomers which are at right angles to an even number or X−1, for example two parallel downcomers are provided so that adjacent trays be turned at right angles so that the downcomers of the upper tray extend centrally between the downcomers of the lower tray. The downcomers reduce stagnant liquid regions, distribute the liquid more evenly on the trays and allow longer flow paths to be provided on the trays.
