Degasifying Means For Liquid Patents (Class 96/155)
  • Patent number: 11098402
    Abstract: A novel method, composition and storage and delivery container for using antimony-containing dopant materials are provided. The composition is selected with sufficient vapor pressure to flow at a steady, sufficient and sustained flow rate into an arc chamber as part of an ion implant process. The antimony-containing material is represented by a non-carbon containing chemical formula, thereby reducing or eliminating the introduction of carbon-based deposits into the ion chamber. The composition is stored in a storage and delivery vessel under stable conditions, which includes a moisture-free environment that does not contain trace amounts of moisture. The storage and delivery container is specifically designed to allow delivery of high purity, vapor phase antimony-containing dopant material at a steady, sufficient and sustained flow rate.

  • Patent number: 9868076
    Abstract: In a process, a portion of a liquid mixture flow is vaporized to produce a vapor and a depleted flow of liquid. The vapor is introduced to a brine which is adapted to exothermically absorb one or more components therefrom, and heat is withdrawn, to produce at least a flow of heat and a flow of brine which is enriched in the one or more components. The heat previously withdrawn is transferred, to drive the vaporization. This transfer can be associated with the change of a working fluid from a gaseous into a liquid gate. In this case, the heat withdrawal involves the change of the working fluid from the liquid to the gaseous state. In the liquid state, the working thud flows only by one or more of gravity, convection and wicking. In the gaseous state, the working fluid flows only by one or more of diffusion and convection.

  • Patent number: 8858682
    Abstract: In order to control bubble removal or mixing in a flow channel, bubble transfer between flow channels (1, 2) is controlled by disposing first flow channel (1) for flow of a first fluid of liquid or gas and second flow channel (2) for flow of a second fluid of liquid with, interposed therebetween, gas exchange unit (5) through which while no liquid can pass, a gas component can be transferred, and by providing a pressure difference between the flow channels (1, 2) with the gas exchange unit (5). By rendering the pressure of the second flow channel (2) higher than that of the first flow channel (1), any bubble transfer from the first fluid to the second fluid is prevented, or bubbles within the second fluid are transferred into the first fluid to thereby attain deaeration.

The vessel has an upper end that tilts downwardly towards a distal end and has a diverging bounding wall so as to define a top wall having a first inclination angle and a bottom wall having a second inclination angle greater than the first inclination angle. A fluid inlet interface at the vessel's upper end discharges a gas stream, having entrained liquids and particulates, into a freeboard portion formed adjacent the top wall above a gas/liquid interface formed below the fluid outlet. A cross-sectional area of the freeboard portion causes precipitation of the entrained liquids and particulates therefrom for collection in a belly storage portion formed below the interface.

The tank flow center has the regular geothermal operation configuration, a system flush configuration, and a refill configuration. The tank flow center may be elevated above the circulation pump a distance to produce a water column that is greater than a minimum cavitation avoidance head pressure for the circulation pump.

  • Patent number: 8540799
    Abstract: A method is provided for degassing a transport chamber (1) of a metering pump. The method is based on performing impulse generation, wherein gas bubbles arising from the gas-forming fluid and adhering to the inner surfaces in the transport chamber (1) are released from the surfaces, wherein the gas bubbles (4.4?, 8.8?) present in the transport chamber (1) accumulate, perform a motion (c) in the direction of the pressure valve (6), and form an accumulated gas bubble (7) on the transport chamber side of the pressure valve (6). An increase in pressure causes the accumulated gas bubble present at the pressure valve (6) to escape from the transport chamber (1) as discharged gas bubbles (7?) into the pressure line. A metering pump having a device present in the transport chamber for performing the impulse generation is also provided.

  • Publication number: 20130242006
    Abstract: Ink in an ink tank is fed through a dissolved gas control filter to a printer head. A gas pressure changing mechanism reduces pressure in a gas pressure control tank. In response, the dissolved gas control filter removes gas dissolved in the ink. The gas pressure control tank is placed under pressure corresponding to a sum of the pressure reduced by the gas pressure changing mechanism and the pressure of the gas having been removed from the liquid. A gas pressure measuring part measures the sum of these pressures as pressure in the gas pressure control tank. Then, a controller determines when time of exchange of the dissolved gas control filter has come based on the magnitude of a gradient of gas pressure variation in the gas pressure control tank.

  • Publication number: 20130199368
    Abstract: The system is provided for continuously separating landfill gas in a raw multi-phase stream coming from a landfill gas collector. The system includes an atmospheric tank and an elongated separator vessel mounted substantially upright above the tank bottom. The elongated separator vessel includes a mid-level inlet that is configured and disposed to be in fluid communication with the landfill gas collector pipe, an upper gas outlet located vertically above the mid-level inlet, and a bottom-opened discharge end that is located vertically below the mid-level inlet. A method of pretreating a raw multi-phase stream captured from a landfill site is also disclosed. The proposed concept provides a relatively simple arrangement that can be made sufficiently rugged to perform a pretreatment of the raw multi-phase stream in a continuous manner and with a very minimal intervention from landfill operators under almost any weather and operating conditions.

  • Patent number: 8491707
    Abstract: A fluid storage tank including an entrained air removal mechanism is provided. The entrained air removal mechanism assists in consolidating small air bubbles entrained within the fluid into larger bubbles such that the air bubbles have sufficient buoyancy to escape the fluid flow. The entrained air removal mechanism may be in the form of a plurality of saw toothed slots communicating different chambers within the fluid storage tank. The fluid storage tank can also be configured to direct fluid flow towards the sidewalls of the fluid storage tank as the fluid transitions from one chamber to another to promote heat transfer out of the fluid storage tank and to avoid the fluid within the tank acting as a thermal insulator.

  • Patent number: RE43941
    Abstract: An apparatus for separating natural gas from production streams comprising a liquid dispersion of water, sand, and natural gas is provided for. The separator comprises a vessel having an interior surface defining a spherical interior space. The interior space allows a production stream introduced therein to experience a velocity drop sufficient to allow separation of the natural gas from the sand and water components. The separator also comprises a stream inlet port in the vessel, a liquid drain in the lower end of the vessel, and a gas outlet port at the upper end of the vessel remote from the stream inlet port. A baffle is mounted in the interior of the vessel in the path of the production stream between the stream inlet port and the gas outlet port. The baffle is effective to spread and direct a high pressure production stream introduced into the interior space via the stream inlet port downward toward the liquid drain.
