Patent number: 8097069Abstract: A pressurized container (10, 20) for containing oil and a gas dissolved therein at a constant overall average pressure at a pressure above atmospheric pressure comprising a means (11a, 11b, 11c, 11d, 21a, 21b, 21c, 21d) for introducing a local area of reduced pressure within the oil. Preferably the local area of reduced pressure result in the gas dissolved in the oil evolving from the oil. This enables gas to be evolved from the oil without needing to reduce the pressure of the entire volume of oil which the gas is to be evolved from. The evolved gas and remaining oil occupy a greater volume than did the gas containing oil and consequently the pressure in the vessel will increase. This will allow the gas to be drawn off while the overall pressure of the container (10, 20) is maintained.Type: GrantFiled: February 13, 2009Date of Patent: January 17, 2012Inventor: David Morgan

Patent number: 7757866Abstract: In an embodiment, axially-fed slurry can be continuously separated into clarified liquid, stripped gas, and thickened sludge in radial counterflow between counter-rotating coaxial centrifugal impellers. One impeller comprises an annular crossflow filter through which liquids are extracted. At the periphery of the impellers, where they are narrowly separated, the sludge is shear thickened into an extruded paste. Suspended solids in the feed pass over the surface of the rotating annular crossflow filter by the shear lift effect, and the vortex-wall interaction jets water radially inward from the periphery, dewatering the sludge. Evolved gases, oils, and fractions lighter than water flow radially inward to the impeller axis through radial vortices in a shear layer between the impellers, and are extracted through an axial exhaust conduit. Feed has long residence time so that separation is complete and continuous. Municipal wastewater, produced water, beverages, food, and scrubber sludge are discussed.Type: GrantFiled: December 20, 2007Date of Patent: July 20, 2010Assignee: McCutchen Co.Inventor: Wilmot H.

Patent number: 5972171Abstract: De-entrainment devices are provided for separating an entrained liquid from a vapor stream exiting a flash zone in a separation column. Methods for utilizing the de-entrainment devices are also provided. In one embodiment, the de-entrainment device of the present invention is embodied in a de-entrainment tray that has a tray deck and a plurality of risers extending vertically up from the tray deck. The risers are provided with devices for imparting rotational movement to the fluid stream, which have the vapor stream and entrained liquid, entering the riser. The rotational movement imparted to the fluid stream causes the liquid to separate from the vapor stream and to flow upward along the riser walls. The de-entrained liquid is then transported from above the separation tray back into the flash zone by way of a liquid downcomer. The vapor stream separates from the liquid within the riser and flows out of the riser upward through the column.Type: GrantFiled: April 8, 1997Date of Patent: October 26, 1999Assignee: Mobil Oil CorporationInventors: Mark Sheldon Ross, Berne K. Stober, John Scott Buchanan

Patent number: 5858070Abstract: An apparatus for cleaning hydraulic fluid includes a centrifugal fluid-spinning disk arranged in a housing, of which an upper portion forms a vapor chamber and a lower portion forms a fluid collecting basin. A vacuum pump is connected to the housing through an oil mist separator, such that water vapor is vacuumed away and hydraulic fluid collects in the oil mist separator to then be pumped away. The apparatus further includes preferably a single container that contains both the contaminated hydraulic fluid that is to be cleaned and the cleaned hydraulic fluid. A flexible inlet line and a flexible outlet line with respective hydraulic quick connectors are provided to connect the apparatus and particularly the oil container to a hydraulic system of an aircraft, for example. A high pressure pump connected to the outlet line pumps the cleaned hydraulic fluid into the aircraft hydraulic system and a pressure maintaining valve in the inlet line maintains the system pressure.Type: GrantFiled: July 14, 1997Date of Patent: January 12, 1999Assignee: Daimler-Benz Aerospace Airbus GmbHInventors: Juergen Halm, Jochen Mertens, Manfred Becher

Patent number: 5749945Abstract: A system is described for rapidly removing dissolved permanent gasses or dissolved volatile contaminants from a liquid, in which the liquid is forced through a cavitating venturi, designed and operated in a fashion to produce micro-bubbles in the high-shear, converging flow section at its entry, to coalesce a significant fraction of these micro-air bubbles in a nominally straight section of maximum restriction following the inlet section, then in a final section, a diffuser, the steam bubbles condense, having during their lives caused coalescence of a significant fraction of the micro air bubbles, which are then, with the water carrying them separated from the remaining stream and its micro-bubbles. The stream separated carries large, easily broken air bubbles which then are broken in a suitable device (four are shown, each with a proposed best design for a specific size of system). The bubbles' contents, a mixture of air, volatiles and vapor are then sent to a vacuum system for processing to the atmosphere.Type: GrantFiled: July 22, 1996Date of Patent: May 12, 1998Inventor: Earl Joseph Beck

Patent number: 5534118Abstract: A controlled bubble of cavitation is formed within the distilland by opposed centrifugal and centripetal forces in the plane of an afferent mesial passage. Thus a distilland surface forms around the axis of rotation, and saturated vapor is continuously stripped from this distilland surface by the work of a vapor pump, which also creates the centripetal force. The vapor vortex within this cavitation region ejects by centrifugal force whatever in it is denser than pure vapor, including any particles or droplets which may somehow become entrained in the vapor. Bubbling at the distilland surface, which might produce mist, is suppressed by centrifugal force. Vapor is compelled to follow an afferent flow path, and is scrubbed by cyclones in the afferent mesial passage. Scrubbed vapor is then withdrawn from within the distilland along the axis of rotation. No container is necessary for the distilland and no heat is added to produce evaporation.Type: GrantFiled: March 7, 1994Date of Patent: July 9, 1996Inventor: Wilmot H. McCutchen
