Abstract
A multiple downcomer tray for a mass transfer column includes a mass transfer area and a plurality of downcomers for collecting and discharging a fluid from the tray. Each downcomer is shaped as a channel with an end wall attachable to an extension element. A downcomer and extension element together extends across the column and supports the panels of the mass transfer area.
