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 pass, turning blocked areas of the tray into active areas. Mass transfer columns containing the trays are also described.

The present disclosure discloses a multi-bubbling region column tray and a corresponding plate column. The multi-bubbling region column tray includes: at least two bubbling regions, provided with first openings for liquid and gas to be mixed and in contact with each other; and at least one non-side downcomer, including at least one hanging downcomer, where the hanging downcomer has a bottom part which includes one or more second openings allowing the liquid to flow toward a lower left side, and one or more third openings allowing the liquid to flow toward a lower right side; and the bottom part of the hanging downcomer is designed to separate the liquid flowing out from the one or more second openings and the liquid flowing out from the one or more third openings.

A contact tray for use in a mass transfer or heat exchange column and having multiple baffles walls that cause the liquid flowing on an upper surface of a tray deck tray to change its direction of flow and narrow its flow path width and extend the length of the flow path when the liquid flows from an inlet area to an outlet on the tray deck. By narrowing the flow path, the volumetric flow rate of the liquid at any portion of the deck increases and reduces the opportunity for vapor entrainment of the liquid at low liquid flow rates. A downcomer extends downwardly from the outlet to receive liquid when it enters the outlet and then convey it downwardly to a discharge outlet located at a lower end of the downcomer. The downcomer includes an inclined or horizontal portion that causes the discharge outlet to be positioned beneath and in vertical alignment with the inlet area on the tray deck.

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.

A distillation system including a retort and a distillation column. The retort includes an inlet end, an outlet end opposite the inlet end and including an outlet opening, a rotatable drum configured to heat a product therein and move the product between the inlet end and the outlet end. The distillation column is coupled to the outlet end of the retort and configured to receive the product therein upon exiting the outlet opening of the retort. The distillation column includes a solid particle trap section positioned above the outlet opening, a packing section positioned above the solid particle trap section and including screen at a bottom end thereof, a dust filter therein, and a first bubble tray section positioned above the packing section and including a first outlet feed for outflow of a first fluid product.
