Abstract: An apparatus and process doubles the number of trays in a single fractionation column. A dividing wall is used to isolate a first side from a second side and fractionation on trays on each side is independent of the other. A transition vapor stream is ducted from a top of a first side to the bottom of the second side, and a transition liquid stream is ducted from a bottom of the second side to the top of the first side.

Abstract: An arrangement of downcomers oriented at a 45-degree angle to a support that is either a wall within a divided wall column or a support beam that allows for reduced spacing of from 0.3 to 0.76 m spacing between trays within a distillation column. The advantages include the use of a single support beam to support two trays as well as more efficient operation and allowing for columns having diameters from 0.9 to 15.2 meters.
