  • Patent number: 8070865
    Abstract: A vacuum vessel for continuous or semi-continuous treatment of oils in connection with deodorization comprises spaces (12, 121, 122) through which oil to be treated is brought to pass and means to heat or cool the oil in the form of U-tubes. There are perforated pipes (26) arranged at the bottom of said spaces to lead stripping gas into said oil. The vessel has a connection to a vacuum source (7). The spaces in the vessel are arranged such that the oil to be treated in the vessel flows through the same by gravity. The heating or cooling medium passing the U-tubes is arranged to be pumped therethrough. The U-tubes for heating or cooling medium are arranged in such a way in said spaces that the flow of oil is counter-current to the flow of heating or cooling medium all through the vessel and a number of U-tubes are arranged in groups (13), parallel and in rows above each other in said spaces.

    Abstract: A riser-based slug control system and a method of controlling slugging in a fluid flowing through a riser are provided. The system includes a gas-liquid separation separator that has a housing defining an internal volume. An inclined inlet is connected to the housing and configured to receive a flow of multiphase fluid and direct the flow of fluid into the housing so that the fluid flows spirally in the volume and separates, with gas from the fluid collecting in an upper portion of the volume and liquid from the fluid collecting in a lower portion of the volume. A tubular passage, which extends at least partially through the internal volume of the housing, defines a plurality of orifices. The tubular passage is configured to receive liquid from the lower portion of the volume and gas from upper portion of the volume, and deliver the mixture of the combined liquid and gas through an outlet.

  • Patent number: 7967892
    Abstract: A water deaerating system and method are provided. The first end of an open-ended conduit is placed beneath the surface of a body of oxygen-rich water. The conduit extends into a housing and where the second end of the conduit resides at a location in the housing that is above the surface of the body of oxygen-rich water. A vacuum is applied to a spatial region defined within the housing above the location of the second end of the conduit. The oxygen-rich water is pumped through the conduit and exits the second end of the conduit to enter the spatial region of the housing. The oxygen-rich water descends through the housing due to gravity. The oxygen-rich water's descension is interrupted and the vacuum operates to remove oxygen from the oxygen-rich water so-descending to generate oxygen-depleted water.

  • Patent number: 7837769
    Abstract: Disclosed is a compressed air powered vacuum mechanism and method for enabling a user to lower atmospheric pressure in enclosed containers and thereby remove carbon dioxide and other entrained gasses from fluids, in this instance wine, in multiple enclosed containers. In a short time, the resulting wine will improve in taste and aroma and clarity, an improvement normally associated with wine that has been naturally aged for many months. A compressed air driven vacuum generator reduces the atmospheric pressure above the wine. When the atmospheric pressure is low enough the entrained gasses will quickly boil off the enclosed wine at room temperatures, disassociating from the fluid, without harming the wine. There are instances in the processing of wine and in keeping containers of food and drink fresh, where following the removing of gasses from the enclosed containers that the vacuum must be retained. This is optionally accomplished with a vacuum retaining on/off mechanism.
