Abstract
A downcomer tray assembly for vapor liquid contact towers. The downcomer is formed with generally semi-conical walls forming a vapor tunnel relative to the discharge region therebeneath. The discharge region is also constructed with a trough and a plurality of venting chambers upstanding therefrom for improving mass transfer efficiency. The venting chambers reduce fluid pressure to vent excess vapor from the underlying tray. The vented vapor is selectively directed into the liquid discharged from the downcomer and allowed to pass through the vapor tunnel. In this manner both entrained liquid and entrained gas can be effectively released to facilitate a stabilized vapor-liquid flow configuration.
