Abstract
Vapor capacity of multiple downcomer type fractionation trays is increased by the provision of vapor directing slots in the tray deck, with the slots being oriented toward the closest downcomer to reduce froth height. The slots located in the relatively narrow deck area between downcomers are accordingly divided into two sets which point in opposite directions. Vertical baffles are provided above the downcomer inlets. The baffles preferably extend upward to slightly below the lower surface of the next higher tray, with the upper edge of the baffles being notched to accommodate the downcomers of this next higher tray.
