ABSTRACT:
The efficiency of multiple downcomer type fractionation trays is improved by the provision of an individual antipenetration pan located under each set of openings in the bottom of the box-like downcomers. The pans preferably comprise perforated planar sheets and have raised lips along two opposing edges to retard significant liquid runoff along the edges parallel to the downcomer end walls. The pans are parallel to the main tray surface and located intermediate the downcomers and the upper surface of the next lower tray.
