Abstract
High capacity, low cost fractionation trays comprise a flat perforated decking surface sectioned into parallel contacting areas by triangular downcomers. The bottom edges of two inclined sidewalls join together to form V-shaped downcomers having a limited number of perforations in their sidewalls to allow downward liquid passage. An imperforate zone is present in the central region of each sidewall. A layer of packing material may be provided close to or adjacent the bottom surface of the tray. The packing is located in the disengagement zone under the tray but does not extend downward to the next tray below.
