Abstract: A device for capturing gas included within a produced-water stream is described. Gas and water pressure coordination is not required. Controls prevent liquid entry to the gas system and prevent gas entry into the water system. A gas/liquid separator receives an inner vessel lower end. A separator inlet receives a combined fluid stream. A liquid line passes into the inner vessel and down into the separator below the inlet so that liquid separated from the combined stream will flow up the liquid line. Motor valves are in the liquid line and in a gas line. The gas line extends from the inner vessel upper end. The gas line conveys gas from the inner vessel upper end to a gas collection system. A top float in the inner vessel activates the gas line motor valve. A bottom float in the inner vessel activates the liquid line motor valve.
Abstract: Method and apparatus for producing an oxygenated fluid. In accordance with various embodiments, a flow of pressurized fluid is established. A flow of oxygen is injected into the flow of pressurized fluid to provide a fluid/oxygen mixture. The mixture is passed through a venturi assembly in the presence of a magnetic field established by an adjacent magnetic assembly. The mixture is next flowed from the venturi assembly to a gas/liquid separation tank, where a liquid component of the mixture is passed downstream with a selected dissolved oxygen content and a gas component is directed back for injection into the pressurized fluid flow.

Abstract: An air conditioning system for automobile having a heater core capable of heating the interior in good efficiency is to be provided. Such a heater core is supplied with the coolant having bubbles removed, and thereby the efficiency of heat exchange is enhanced and the noise is reduced. On the internal combustion engine is mounted a water outlet (bubble separating means) 3 having a receiving chamber 8 that the coolant after cooling the engine flows in. In the downstream position of the chamber 8 is formed a communicating portion 9 of narrowed sectional area and a feeding chamber 10 of increased sectional area in turn. The flowing velocity of the coolant is increased in the communicating portion 9 and decreased in the feeding chamber 10 and thereby it is possible to make bubbles in the coolant float up and separate out. As a result, the coolant without bubbles may be fed to the heater core 7 through a feeding portion 11.

Abstract: The piping with a coolant inlet is provided with a partition wall within a body part. In the body part, a flow path having a U-turn region changing the flow direction of a coolant by about 180° degrees is defined. Much of the air contained in the coolant returning from a communicating hole to the body part floats up in a region leading to the U-turn region and is released from an inlet to the outside. By using this configuration, it is possible to provide a piping with a coolant inlet having a structure capable of efficiently releasing the air generated in a coolant circulation path.

Abstract: A long-term, reliable high pressure reference electrode for high temperature applications was disclosed. This reference electrode has inner and an outer liquid junction plugs. The inner plug provides the function of restraining the outflow of the internal reference electrolyte. The outer plug is chemically and mechanically robust in the external fluid where the reference electrode is used and protects the inner plug from the mechanical and chemical attacks by the harsh external fluid. Therefore, the inner plug can be selected from many of the well-characterized liquid junction plugs used in regular low temperature reference electrodes, without the need for the inner plug to be chemically and mechanically stable in the external fluid, as long as it has the thermal stability. A method for preventing the formation of gas bubbles inside a high pressure reference electrode in the electrolyte-filled section, and thus eliminating the gas bobble effect on the electrical continuity, was also disclosed.

Abstract: In an upflow reactor for reacting heavy hydrocarbons with hydrogen gas in a liquefied catalyst slurry, that mixture is recirculated down through a downcomer having an upper degassing section which includes a frusto-conical upper surface. The mixture is caused to flow along that surface in a downward helical path, such that heavier components are centrifugally urged outwardly, and lighter components, e.g., gas, migrate inwardly. The gas bubbles can thus coalesce such that small bubbles become bigger bubbles having a greater tendency to rise out of the downcomer. Baffles placed on the upper surface can maximize the residence time of the mixture in the degassing section.

Abstract: A mechanical vessel may effectively and simultaneously displace a first undesired gas from within water with a second desired gas, and remove at least one alkaline species and oily matter from the water. The vessel raises the pH of the water and reduces the lime requirement for subsequent lime softening.

Each gasification chamber may have a mechanism that ingests and mixes a second gas into the water thereby physically displacing at least a portion of the first gas into a vapor space at the top of each gasification chamber from which it is subsequently removed. There is an absence of communication between the vapor spaces of adjacent chambers. An acid is added to remove the alkaline species, where the first gas is an optional by-product that is also removed.

The due operation and/or maintenance of the device is associated with the formation of inclusions (3) inside the channel (1) of a fluid or gas distinct from the aforementioned medium. The channel (1) is configured in such a manner that the inclusions are moved towards a channel exit (4) by capillary forces. The invention also relates to a method for removing inclusions (3) from corresponding devices.
