"APPLIANCE INTENDED TO FACILITATE IMPROVED INTERACTION OF STEAM AND LIQUID THAT PASSES IN CONTRA-CURRENT FLOW THROUGH A PROCESSING TOWER, AND, MIXING PROCESS OF A GAS WITH A LIQUID DISCHARGED FROM A DOWNLIGHT TUBE. CHEMICAL PROCESSING TOWER ". An improved descending tube for vapor-liquid contact towers. Such a descending tube is formed between generally semi-conical walls and the tower wall. The outlet of the down tube is formed by the lower edge of the walls generally semi-conical and the wall of the tower, with the bottom edge of the walls generally semi-conical being closer to the wall of the tower in the center of the outlet of the down tube than in the opposite end portions of the downstream outlet such that a greater amount of liquid will flow through the opposite end portions of the downstream outlet than in the center of the downstream outlet, thereby promoting a substantially uniform flow of liquid over the along the tray adjacent to the descending tube.
