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 vent excess vapor from the underlying tray. The vented vapor is selectively directed into the liquid discharged from the downcomer and imparted with a horizontal flow characteristic. In this manner both entrained liquid and entrained gas can be effectively released to facilitate a stabilized vapor-liquid flow configuration.
