The method includes drawing a quantity of gas into the chamber to empty the chamber of fluid, maintaining the chamber in an empty state for a predetermined period of time, and then refilling the chamber with fluid at a rate low enough to remove remaining bubbles and to prevent the formation and trapping of new bubbles within the chamber.Type: GrantFiled: May 5, 2000Date of Patent: November 29, 2005Assignee: Segars California Partners LPInventor: James H. Macemon

Patent number: 6872239Abstract: A method for separating phases of a mixture comprising and oil-water together with gas. At least a substantial part of the gas is separated from the emulsion before the emulsion is introduced into a separator tank. The oil-water emulsion from which the gas has been separated is conducted to a liquid-liquid cyclone for further separating the phases of the emulsion. The liquid-liquid cyclone is located inside the separator tank. The emulsion is conducted to the separator tank for separating the oil from the water.Type: GrantFiled: April 23, 2001Date of Patent: March 29, 2005Assignee: ABB Research Ltd.Inventors: Pål J. Nilsen, Erik A. Wolff

Patent number: 6800116Abstract: Discloses apparatus and method to deaerate and condition bitumen froth obtained from a primary tar sands bitumen extraction process comprising a vessel containing a plurality of inclined plates, called a static deaeration conditioner. The inclined plates of the static deaeration conditioner are substantially equidistantly spaced from each other and are inclined at an angle to the horizontal. The plates form a corresponding plurality of channels there between for the froth to be deaerated to flow along. The declination angle is selected to obtain a gravity induced froth flow rate in the channel that exhibits a lamella effect near laminar flow characteristics, which promotes the creation of a water-enriched froth region near the lower plate of the channel. A braking pump can be provided on an outlet port of the vessel to control the rate of flow through the vessel of the froth to be deaerated and conditioned.Type: GrantFiled: July 18, 2002Date of Patent: October 5, 2004Assignee: Suncor Energy Inc.Inventors: Geoffrey Stewart Stevens, Donald Norman Madge, William Lester Strand

Patent number: 6790256Abstract: A system for monitoring gas carry-under of a formation fluid exiting a gas separator by measuring a parameter of interest of the formation fluid exiting the gas separator is disclosed. The parameter of interest that can be correlated with the extent of gas entrained in the formation fluid exiting the separator can be the density of the formation fluid, or an absorbance spectrum of the formation fluid. A correlation of the measurement of the parameter of interest with a level of gas carry-under is made and a signal is transmitted to a device to control the supply of at least one additive to control the gas carry-under.Type: GrantFiled: September 25, 2002Date of Patent: September 14, 2004Assignee: Baker Hughes IncorporatedInventor: C. Mitch Means

Patent number: 6616733Abstract: A method and apparatus for filtering an air stream with an aqueous froth are provided. The process includes: passing a contaminated air stream through a diffusing sieve, into an aqueous solution in an expansion chamber; generating, maintaining, and containing an aqueous froth between the liquid-bath reservoir and a saturated fiber element; and continually saturating a coarse-fiber element with liquid from the aqueous solution. The froth is generated and maintained, and the fiber element is saturated, by controlling the dynamic interface between the contaminated air stream and the liquid-bath reservoir. The apparatus for filtering an air stream includes: an air filter device that incorporates a liquid-bath filter initial stage; an aqueous-froth filter second stage; a constantly saturated, coarse-fiber filter as a combined third stage and froth-limiter; and a moist, fine-fiber filter as the final stage.Type: GrantFiled: July 10, 2001Date of Patent: September 9, 2003Assignee: Peletex, Inc.Inventor: Roy J. Pellegrin
