  • Patent number: 11541328
    Abstract: 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.

  • Patent number: 11484822
    Abstract: A vane inlet device is provided in a vessel to receive and redistribute a fluid stream entering the vessel and to facilitate separation of liquid from the fluid stream. The vane inlet device includes a passageway bounded by a top plate and a bottom plate spaced from the top plate. First and second arrays of vanes extend between the top and bottom plates and are positioned to receive respective portions of the fluid stream flowing from an inlet end of the passageway toward an opposite end and redirecting it out opposite sides of the passageway. A spacing between the first array of vanes and the second array of vanes progressively decreases in a direction from the inlet end of the passageway toward the opposite end. A beam extends from the top plate to the bottom plate between the first and second arrays of vanes to reduce flexure of the top and bottom plates and to separate the respective portions of the fluid stream.

  • Patent number: 11471786
    Abstract: The invention is directed to a method for recovering at least one product from a fermentation broth. The invention relates to the use of a vacuum distillation vessel to recover products, such as ethanol, from a fermentation broth, where the fermentation broth comprises viable microbial biomass, and where the recovery of the product is completed in such a manner to ensure the viability of the microbial biomass. The invention provides for product recovery at an effective rate so as to prevent the accumulation of product in the fermentation broth. To ensure the viability of the microbial biomass, the invention is designed to reduce the amount of stress on the microbial biomass. By ensuring the viability of the microbial biomass, the microbial biomass may be recycled and reused in the fermentation process, which may result in an increased efficiency of the fermentation process.

A plurality of barriers are positioned between the inlet area and the outlet. The barriers each have spaced-apart pickets and openings in the spacing between adjacent ones of the pickets. The pickets impede the flow of the liquid and increase the upstream liquid loading on the tray deck as the liquid flows from the inlet area, through the openings, and then into the outlet. At low liquid flow rates, this increase in the liquid loading may significantly increase the vapor handling capacity of the tray.

  • Patent number: 9968895
    Abstract: A submersible aerator apparatus is disclosed. The apparatus uses injected air to create both aeration and mixing of a liquid. The apparatus is submersible and may be lowered into a container holding a liquid with suspended and coagulated solids. Air supplied to the apparatus is injected into the liquid which results in an upward flow of air bubbles and entrained liquid. This action mixes and aerates the liquid. A method of using a submersible air-injection aerator is also disclosed.

  • Patent number: 9815018
    Abstract: The gas separation device separates or captures a target gas component from a gas to be processed by: causing an absorbing liquid to flow down on a surface of a packing disposed inside a processing tank while supplying the gas to be processed containing the target gas component into the processing tank; bringing the absorbing liquid flowing down on the surface of the packing and the gas to be processed into gas-liquid contact; and thereby causing the absorbing liquid to absorb the target gas component contained in the gas to be processed. The packing includes at least one packing unit formed from multiple expanded metal plates, which are disposed vertically and arranged in parallel. Each expanded metal plate includes strands forming the openings which are arranged like stairs. Each strand is inclined to the vertical direction at an angle in a range from 48° to 73°.

  • Patent number: 9625817
    Abstract: The present invention relates to a special heteropolymer, namely a silicic acid (hetero)poly(co)condensate with positive-resist behavior which is distinguished by polycondensation or copolycondensation of specially modified silanes. The invention relates likewise to monomeric silanes from which the corresponding heteropolymers, i.e. the silicic acid (hetero)poly(co)condensates, can be produced. The silicic acid (hetero)poly(co)condensates according to the invention can be used for a photoresist which has positive-resist behavior. In addition, the invention relates to corresponding methods both for the production of the silanes, the silicic acid (hetero)poly(co)condensates or a method for photochemical structuring of the photoresist according to the invention which is based on the silicic acid (hetero)poly(co)condensates.

  • Patent number: 9546330
    Abstract: A system and process for upgrading a whole crude oil feed in an integrated ebullated-bed and hydrotreater is provided in which the whole crude oil is flashed into a flashed straight run distillates fraction and an atmospheric residue fraction. The atmospheric residue fraction is hydroprocessed in an ebullated-bed reaction zone, while the flashed straight run distillates fraction and the products fraction produced from the ebullated-bed reaction zone are hydrotreated in a fixed-bed reaction zone. Distillates from the hydrotreater and the unconverted residue fraction from the ebullated-bed reaction zone can be combined to produce an upgraded synthetic crude oil.

  • Patent number: 9193607
    Abstract: Water treatment apparatus for supplying ozonated water to appliances, such as clothes washing machines. First and second water aspirators include respective first and second Venturi tubes. One aspirator is designed for a relatively higher water flow rate, and the other is designed for a relatively lower water flow rate. A valve selectively directs water from a water inlet to a water outlet through either the first or the second water aspirator. Ozone from an ozone generator is drawn either into water flowing through the first Venturi tube or water flowing through the second Venturi tube, depending on the position of the valve. A water flow sensor includes a microphone physically connected for sensing a sound characteristic of operation of a Venturi tube. A controller effects a time delay for maintaining activation of the ozone generator for a predetermined time duration even after water flow has ceased.
