Abstract
A tray device has a plurality of chimneys which extend above the level of liquid in the tray and have vapor outlets for the passage of the rising vapor. Tubes are also provided in the tray device with liquid inlets for the passage of liquid from the tray downwardly onto the lower exchange section. The tray device intercepts the liquid trickling down from an upper exchange section and distributes the liquid uniformly through the tubes over the top cross section of the exchange section immediately below. The vapor rising from the bottom section passes through the chimneys separately from the liquid.
