Abstract
High capacity, low cost fractionation trays are formed from a number of adjacent triangular (v-shaped) downcomer modules. The trays are free of the horizontal perforated decking surface of conventional trays. The downcomer modules have perforations only in a bottom region for liquid passage and in an upper region for vapor passage, with the central portion of the two inclined downcomer sidewalls being imperforate. The difference in elevation between the bottom region and upper region is considerably larger than a ripple tray. A layer of packing material may be provided close to or adjacent the bottom surface of the tray.
