  • Patent number: 11691105
    Abstract: A gas-liquid contacting apparatus and method are described, in which at least one rotor assembly including packing is arranged in a contacting chamber containing at least one stator assembly including at least one heat exchanger arranged to thermally modulate the gas-liquid contacting so that each stator assembly is operatively arranged with each stator assembly to provide gas-liquid contacting at temperatures effective for mass exchange between the gas and liquid. The rotor and stator assemblies may be of annular shape, or may be of disk shape in a stacked array of rotor assemblies alternating with stator assemblies. Such apparatus and method are usefully employed for CO2 capture from CO2-containing flue gases such as combustion effluents from power generation plants.

  • Patent number: 11647993
    Abstract: An oral fluid collection device is provided that includes a borosilicate glass collection tube that can be capped post-collection for containing a human donor's expectorated oral fluid. The collection tube has a lyophilized reagent disposed therein that is essentially free of surfactants and solvents and includes a bacteriostatic, a peptidoglycan cleaving enzyme, an esterase inhibitor, an antioxidant, and a buffer at a pH range of about 5.7 to about 6.5 for stabilizing drugs and drug metabolites that may be present in the donor oral fluid. Interaction between the collected oral fluid and the buffer-preservative is provided by gravity drawing the collected oral fluid downward into contact with the lyophilized buffer-preservative.

  • Patent number: 11649777
    Abstract: An internal combustion engine is operated at fuel-rich conditions by adjusting one or more operating parameters such as, for example, a throttle, an ignition timing, a load coupled to the engine, a fuel pressure, power to a supercharger, and power to a preheater to maintain a specified engine speed and a temperature of an exhaust gas. Operating the engine under these conditions allows the engine to function as a reformer producing a synthesis gas comprising hydrogen and carbon monoxide.

  • Patent number: 11648202
    Abstract: Water-dispersible pharmaceutical compositions of hydroxychloroquine sulfate in powder or granule form are provided that allow for ease of preparation of measured-dose, liquid suspensions that are palatable and suitable for pediatric administration. The compositions in granular or powder form are efficiently dissolvable in water and can be provided encapsulated within a two-piece releasable hard capsule or a packet or pouch for easy release. An ion-pairing agent is present in the formulation of the composition that masks the bitter taste of the hydroxychloroquine sulfate, significantly reducing the need for addition of a sweetening agent. Methods are provided for preparing the water-dispersible pharmaceutical compositions of hydroxychloroquine sulfate and for preparing palatable weight-based pediatric doses.

  • Patent number: 11491457
    Abstract: Zinc oxide-based sorbents, and processes for preparing and using them are provided, wherein the sorbents are preferably used to remove one or more reduced sulfur species from gas streams. The sorbents contain an active zinc component, optionally in combination with one or more promoter components and/or one or more substantially inert components. The active zinc component is a two-phase material, consisting essentially of a zinc oxide (ZnO) phase and a zinc aluminate (ZnAl2O4) phase. Each of the two phases is characterized by a relatively small crystallite size of typically less than about 50 nm (500 Angstroms). Preferably the sorbents are prepared by using an alkali metal base to convert a precursor mixture, containing a precipitated zinc oxide precursor and a precipitated aluminum oxide precursor, to the two-phase, active zinc oxide containing component, with the resulting sorbent having a sodium level within a desired range.

  • Patent number: 11413572
    Abstract: A method with corresponding systems for reducing emission of amines to the atmosphere. The method includes a a) introducing a gas containing CO2 into an absorber; b) flowing the flue gas through an absorber having an absorbent with a water-lean solution having less than 50% water and one or more amines, with the absorbent capturing the CO2 and forming a reduced CO2 content gas having a baseline CO2 content; and c) washing the reduced CO2 content gas in a wash column with a wash solution comprising carbonic acid formed by addition of gaseous CO2 into the wash solution. In this method, the washing removes the amines from the reduced CO2 content gas and produces a reduced amine content gas exiting from the wash column.
