Abstract: Distillation trays having improved efficiency and capacity are described. The improvement is accomplished with unique downcomer spout arrangements and bubble promoters which provide equal liquid distribution to all areas of the tray. The ratio of the open area of a contacting zone including part of a bubble promoter and associated deck zone over the open area of the downcomer spout zone on the adjacent tray for distributing liquid to the zone is essentially the same across the tray.

Abstract: Trays having increased capacity and efficiency are described. The trays have a deck, and downcomers extending through the deck. There are a plurality of bubble promoters on the deck. Each bubble promoter defines a zone on the deck, and the zone has an opening in the deck. The opening is positioned adjacent to a solid support for the tray. The bubble promoters provide areas through which vapor can passing, turning blocked areas of the tray into active areas. Mass transfer columns containing the trays are also described.

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.
