Abstract: An apparatus has a body with a wall defining at least in part an enclosed chamber. The wall has a first opening providing fluid flow into the chamber and a second opening providing fluid flow out of the chamber. The wall has a vent allowing gas to pass outwardly from the chamber. An outlet tube extends from the second opening into the chamber and an aperture. The aperture allows fluid within the chamber to enter the outlet tube and flow outwardly from the chamber through the second opening. Bubbles within the chamber are prevented from entering the outlet tube regardless of the orientation of the body.

Abstract: A water stream is treated to remove oxygen before injecting the water into an underground hydrocarbon reservoir. The water-oxygen mixture is separated by centrifugal action using fixed spin blades (20). Oxygen is removed from the center of the conduit through a gas pipe (30) coupled to a vacuum pump (50). Nitrogen may be introduced upstream of the centrifuge to dilute the water-gas solution to improve the efficiency of the gas-liquid separation.

The container has an upper open end surrounded by a lip. When the container is filled, de-aerated fluid spills over the lip and falls into the sump.

Abstract: Apparatus and method for degassing liquids particularly cationic monomers. Fluid comprising liquid to be degassed together with sweep gas is admitted tangentially into a column (10) and forced down the column by a tubular baffle (16) which defines, with the inner wall of the column, an annulus (18) that is closed at its top (20). After passing to the bottom of the annulus the fluid forms an even film over the inner surface of the column and gas disengaging from the liquid can rise up the column while liquid accumulates at the bottom of the column. To assist the disengagement of the gas from the liquid the column is preferably of increasing cross section towards the bottom so that the thickness of the film is also reduced.

Abstract: A liquid-gas separator assembly is used in separating gas bubbles from a liquid coolant. 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. The gaseous component of the separated mixture is then expelled from the housing through an outlet in the upper portion of the housing, and the coolant liquid descends through the annular chamber to the bottom of the housing.

Abstract: A degassing device capable of regulating an amount of air dissolved in a liquid. A device for measuring amounts of dissolved oxygen measures the amount of oxygen dissolved in one of a coating liquid which has yet to be degassed, and is to be fed to a film degassing device, and a coating liquid which has been degassed and discharged from the film degassing device. Based on measured results, a control unit regulates the degree of opening of a vacuum valve so as to change the degree of degassing performed by the film degassing device, thereby suppressing fluctuations in an amount of oxygen dissolved in the coating liquid. A load never constantly acts on the film all the time, the film life can accordingly be extended, thus resulting in reductions in running costs.
