Patent number: 11738284Abstract: 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.Type: GrantFiled: December 28, 2021Date of Patent: August 29, 2023Assignee: UOP LLCInventors: Zhanping Xu, Brian J. Nowak

Patent number: 11554328Abstract: 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.Type: GrantFiled: March 6, 2020Date of Patent: January 17, 2023Assignee: UOP LLCInventors: Brian J. Nowak, Zhanping Xu, Peter J. Wantuck

Patent number: 10792585Abstract: 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.Type: GrantFiled: March 29, 2018Date of Patent: October 6, 2020Assignee: UOP LLCInventors: Brian J. Nowak, Kevin J. Richardson

Patent number: 10471370Abstract: 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.Type: GrantFiled: August 29, 2018Date of Patent: November 12, 2019Assignee: UOP LLCInventors: Kevin J. Richardson, Brian J. Nowak, Michael J. Behm, David M. Wollaber, Shanda G. Fry

Patent number: 8020838Abstract: Improved contacting stages for carrying out vapor-liquid contacting are described. Particular aspects are directed to co-current vapor-liquid contacting devices with non-parallel contacting stages that provide an efficient usage of column space for fluid flow and contacting, in order to achieve high capacity, high efficiency, and low pressure drop. The fabrication of such contacting stages is improved using one or more structural enhancements, preferably a combination of enhancements, to achieve easy installation and significantly improved rigidity between the various parts and thereby avoid movement/separation of these parts. This reduces the possibility of fluid leakage across, and consequently vapor and/or liquid bypassing of, the contacting stage.Type: GrantFiled: March 31, 2009Date of Patent: September 20, 2011Assignee: UOP LLCInventors: Thomas C. Heldwein, Joseph Agnello, Aaron J. Muck, Zhanping Xu, Brian J. Nowak

Patent number: 7424999Abstract: The invention is a high capacity and high efficiency co-current vapor-liquid contacting apparatus for use in distillation columns and other vapor-liquid contacting processes. The apparatus is characterized by an arrangement of modules in horizontal stages rather than tray-like construction. The modules define a co-current contacting volume and in an exemplary configuration the modules include a liquid distributor, a demister, a receiving pan and a duct. The modules of one stage are rotated to be non-parallel with respect to the modules of an inferior stage, a superior stage, or both. Variations relate to the design of the individual elements such as the demister, liquid distributor, ducts, and contacting volumes, and the overall arrangement of the apparatus.Type: GrantFiled: May 10, 2006Date of Patent: September 16, 2008Assignee: UOP LLCInventors: Zhanping Xu, Brian J.

Patent number: 7370846Abstract: The invention comprises multiple configurations of downcomers in a parallel flow multiple downcomer tray for vapor-liquid contacting processes such as the separation of chemical compounds via fractional distillation or the removal of a component of a gas stream with a treating liquid. In one embodiment, side downcomers are incorporated into a parallel flow multiple downcomer tray. In another embodiment, the downcomers have an inclined side wall that directs liquid onto the deck below the downcomer. The inclined side wall also provides additional volume above the inferior downcomer inlet to reduce pinching at this inlet without the need for a stilling deck.Type: GrantFiled: October 17, 2006Date of Patent: May 13, 2008Assignee: UOP LLCInventors: Zhanping Xu, Daniel R. Monkelbaan, Brian J. Nowak, Robert J. Miller
