Patent number: 11738286Abstract: A rotary counter-current solid/fluid contact apparatus is developed to enhance the efficiency of adsorption, ion exchange and regenerative heat exchange. The counter-current apparatus uses a rotor to direct fluids to multiple stationary columns. By the action of the rotor, counter-current flows of a fluid phase and a solid phase can be achieved for a combined adsorption and desorption cycle, or a combined heating and cooling cycle. The apparatus allows not only countercurrent solid-fluid flows based on columns in series, but also countercurrent solid-fluid flows in the length of each individual column. A method is also disclosed.Type: GrantFiled: July 12, 2021Date of Patent: August 29, 2023Inventor: Baisheng Zou

Patent number: 11547967Abstract: A process is presented to treat a process gas stream containing hydrogen sulfide using a reverse jet absorber with a liquid treatment solution containing a chelated metal catalyst. A treat gas substantially free of the hydrogen sulfide is separated from a spent liquid treatment solution containing elemental sulfur which can then be regenerated in an oxidation vessel where it is contacted with an oxygen containing gas to convert the spent liquid treatment solution to a regenerated liquid treatment solution that can be recycled for introduction into the reverse jet absorber.Type: GrantFiled: June 17, 2021Date of Patent: January 10, 2023Assignee: MERICHEM COMPANYInventors: Baisheng Zou, Jeffrey B. Gomach, David Jackson

Patent number: 11339334Abstract: A method may include: introducing a fluid comprising a first immiscible phase and a second immiscible phase into a contacting vessel comprising multiple contact stages: flowing the fluid through a first fiber bundle disposed in the contacting vessel; separating at least a portion of the first immiscible phase from the second immiscible phase; and flowing the separated portion of the first immiscible phase through a second fiber bundle disposed in the contacting vessel.Type: GrantFiled: February 6, 2020Date of Patent: May 24, 2022Assignee: Merichem CompanyInventors: Jeffrey Bruce Gomach, John Jagger, Baisheng Zou, James McGehee

Patent number: 11248175Abstract: An improved contactor/separator process is presented where one or more stages of contact and separation is achieved by providing one or more shroud and disengagement device combinations within a vessel, where the disengagement device is connected to the top of the shroud that contains vertically hanging fibers. A liquid admixture of immiscible fluids is directed co-currently upward through the shroud at flooding velocity or greater, where all of the admixture exits the disengagement device through a coalescing material. Tray supports are used to stack additional shroud and disengagement combinations vertically within the vessel. Each tray allows less dense liquids exiting one disengagement device from a lower shroud and disengagement device combination to enter the bottom of a shroud of a shroud and disengagement device combination position vertically above the lower shroud and disengagement device combination.Type: GrantFiled: November 4, 2020Date of Patent: February 15, 2022Assignee: MERICHEM COMPANYInventors: James F.
