Abstract
A downcomer tray assembly for vapor liquid contact towers. The region of the tray beneath an upper downcomer is constructed with a raised, perforated region for improving mass transfer efficiency. The raised region reduces fluid pressure to facilitate ascending vapor therethrough. A series of louvers selectively directs the upward vapor flow into the liquid region below the downcomer to generate a more efficient vapor-liquid contact and reduced back-mixing across the tray.
