Abstract

A downcomer-tray assembly for vapor liquid contact towers with enlarged effective active areas. The downcomers are constructed with support baffles enabling intermediate areas of the downcomer-tray to be supported therefrom and outer areas of the downcomer-tray to be supported by an active tower support ring. An active bridge may be used between end-to-end downcomers for maximizing the active area of the associated tray.
