Patent number: 7670702Abstract: A liquid-gas separator assembly is used in separating gas bubbles from a liquid coolant which liquid coolant is used in a polymer electrolyte membrane (PEM) fuel cell power plant. The assembly includes a cylindrical housing containing a central tube which is surrounded by an annular chamber. The annular chamber is defined by the outer surface of the central tube and the inner surface of the cylindrical housing. An inlet line injects a stream of the coolant from the fuel cell stack area of the power plant into the bottom of the central tube in a tangential flow pattern so that the coolant and gas bubble mixture swirls upwardly through the central tube. The swirling flow pattern of the coolant and gas bubble mixture causes the gas bubbles to separate from the liquid coolant so that the gas in the mixture will migrate to the central portion of the swirl tube and the liquid component of the mixture will centrifugally migrate to the inner wall of the swirl tube.Type: GrantFiled: October 20, 2005Date of Patent: March 2, 2010Assignee: UTC Power Corp.Inventor: Albert P.

Publication number: 20090205497Abstract: A pressurised 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: ApplicationFiled: February 13, 2009Publication date: August 20, 2009Inventor: David Morgan

Patent number: 7122071Abstract: A gas-liquid separator uses a helical passageway to impart a spiral motion to a fluid passing therethrough. The centrifugal force generated by the spiraling motion urges the liquid component of the fluid radially outward which forces the gas component radially inward. The gas component is then separated through a gas-permeable, liquid-impervious membrane and discharged through a central passageway. A filter material captures target substances contained in the fluid.Type: GrantFiled: September 25, 2002Date of Patent: October 17, 2006Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Steve R. Gonda, Yow-Min D. Tsao, Wenshan Lee

Patent number: 7118819Abstract: A liquid-gas separator assembly is used in separating gas bubbles from a liquid coolant which liquid coolant is used in a polymer electrolyte membrane (PEM) fuel cell power plant. The assembly includes a cylindrical housing containing a central tube which is surrounded by an annular chamber. The annular chamber is defined by the outer surface of the central tube and the inner surface of the cylindrical housing. An inlet line injects a stream of the coolant from the fuel cell stack area of the power plant into the bottom of the central tube in a tangential flow pattern so that the coolant and gas bubble mixture swirls upwardly through the central tube. The swirling flow pattern of the coolant and gas bubble mixture causes the gas bubbles to separate from the liquid coolant so that the gas in the mixture will migrate to the central portion of the swirl tube and the liquid component of the mixture will centrifugally migrate to the inner wall of the swirl tube.Type: GrantFiled: June 17, 2002Date of Patent: October 10, 2006Assignee: UTC Fuel Cells LLCInventor: Albert P. Grasso

Patent number: 7105044Abstract: A fluid tank fluid is provided which includes a bubble removing device provided therein to remove bubbles from the fluid. The bubble removing device includes a cyclone chamber for generating a swirling current in the fluid flowing therethrough to separate bubbles from the fluid. At least one outflow port is provided through which the fluid from which the bubbles have been separated flows from the cyclone chamber. And an exhaust port is provided through which the bubbles separated from the fluid are driven from the cyclone chamber.Type: GrantFiled: May 21, 2003Date of Patent: September 12, 2006Assignee: Komatsu Ltd.Inventors: Akiko Konishi, Shotaro Ishii, Kouji Chikaishi, Noboru Kanayama, Tatsuro Nohara

Patent number: 6918949Abstract: A method for contacting large volumes of gas and liquid together on a microscopic scale for mass transfer or transport processes wherein the contact between liquid and gas occurs at the interfaces of a multitude of gas bubbles. Multiple porous tubes assembled in a bundle inside a pressure vessel terminate at each end in a tube sheet. A thin film helical liquid flow is introduced into the inside of each porous tube around and along its inside wall. Gas is sparged into the porous media and the liquid film so that an annular two phase flow with a uniform distribution of tiny gas bubbles results. The gas flow is segregated from the liquid flow without first passing through the porous media and through the liquid film. Nozzles at the lower end of the tubes divert liquid flow to a vessel and redirect the gas flow in a countercurrent direction.Type: GrantFiled: November 5, 2004Date of Patent: July 19, 2005Assignee: Jaeco Technology, Inc.Inventor: Janet K. Peters

Patent number: 6896819Abstract: A method for treating liquid includes directing a pressurized stream of the liquid into a cyclone apparatus having an inlet closed to the atmosphere and a submerged outlet. A liquid vortex is formed along an inner surface of the cyclone apparatus, and a central portion defined by an inner surface of the liquid vortex is substantially evacuated of gases to create a near vacuum condition. Treatment gas may be selectively added to the liquid vortex through the evacuated central portion. Photon energy may be directed through the evacuated central portion and into contact with the treatment gas, or the liquid vortex. Pressure levels within the evacuated central portion are measured using a pressure sensor or gauge. Upon exiting the cyclone apparatus, the liquid is subjected to collision and cavitation forces.Type: GrantFiled: June 24, 2003Date of Patent: May 24, 2005Inventors: Dwain E. Morse, Wade O. Morse, Thomas G. Matherly

Patent number: 6884401Abstract: A high viscosity liquid is fed into a rotation pack bed at a position with a distance far enough from a rotation axis, creating a centrifugal force exerted on the high viscosity liquid overwhelming a drag thereof, so that it can flow radially through the rotation pack bed. A high pressure gas is introduced into the rotation pack bed peripherally and/or a suction force source is connected to a position near the rotation axis, so that a volatile component contained in the high viscosity fluid is entrained in the gas counter currently flowing through the rotation pack bed and withdrawn from the position near the rotation axis, or the volatile component exits from the position near the rotation axis in gas phase, and thus the volatile component is removed from the high viscosity liquid. A second fluid can also be fed into the rotation pack bed to react with the high viscosity liquid, so that a reaction product is formed, and a volatile side product is removed at the same time.Type: GrantFiled: July 17, 2002Date of Patent: April 26, 2005Assignee: Industiral Technology Research InstituteInventors: Sheng Yang, Chia-Chang Lin, I-Min Tseng, Wen-Tzong Liu, Hua-Tang Yu

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.
