description A tray assembly is provided for improved gas/liquid contact when used in a large chemical process tower. Each tray has a downcomer wall of which the lower portion is a distributor. The distributor has discharge ports sized to control the rate of liquid flow at different positions across the distributor and flanges aligned individually to direct liquid flow from different discharge ports across different areas of the tray deck immediately below the downcomer. In combination, discharge ports and liquid flow directing flanges effect even liquid flow across the surface of the tray immediately below. Benefits of this invention are trays with better mass transfer efficiency and enhanced capacity compared with prior art trays.
