ABSTRACT:
In a crossflow gas-liquid contact tower, liquid moves horizontally across a plurality of vertically spaced trays, and downwardly from tray-to-tray while gas flows up through openings in the trays to create a liquid-vapor mixture in an active bubble area. Each tray is formed of panels with mutually overlapping margin portions. Overlapping vapor openings are formed in the overlapping margin portions in order to provide the tray with a greater open area and with a more uniform aperture distribution. Preferably, each opening includes an aperture in the plane of the tray, and a deflector overlies the aperture to define lateral vapor outlet slots. The aperture is wider at its upstream end than at its downstream end; and, the deflector has upstream and downstream portions which extend across the ends of the aperture.
