  • Patent number: 10913279
    Abstract: A liquid material filling device and method are provided which are intended to prevent air bubbles from remaining along an entire length of a flow passage extending from a liquid material reservoir (51) to a discharge port (53). The liquid material filling device includes a chamber (10) of an airtight structure, a pressure regulator (70) for regulating pressure in the chamber (10), and a control device (100). The liquid material is filled as follows. A negative pressure supply source (71) is communicated with a chamber communication pipe (90) and with a discharge device communication pipe (91) to reduce the pressure in the chamber (10) and pressure in an upper space of the reservoir (51) to a vacuum or a low pressure level close to a vacuum, and a resulted low-pressure state is maintained for a certain time to expel out air bubbles in the liquid material.

  • Patent number: 9068580
    Abstract: A venting device for a hydraulic control unit, designed as a diaphragm in a bore in the control unit, so that collected air can escape, via the diaphragm, to outside the housing. A membrane, which is permeable to air and oil when under pressure, closes the diaphragm bore with respect to the outside. The housing bore and the diaphragm form an inside space that can be vented, via the membrane. The inside space being delimited, during operation, by the diaphragm and an oil column which passes from the control unit into the housing bore and is continually maintained at a defined pressure at which oil, in the housing bore, either does not pass through the membrane or only a minute amount passes therethrough. The oil column remains in the housing bore so that only air, contained in the oil, is vented to the outside without any air being drawn into the control unit from outside.

  • Publication number: 20130180404
    Abstract: An apparatus and process to effectively create an active drain for high and low pressure gas-liquid separator. The invention accomplishes a deterministic drainage rate of variable volume and viscosity liquid fractions from the separator. The mechanisms and methods thereof create a flow path from the separator that dramatically favors controlled liquid flow over a wide range of flow rates and viscosities while restricting gas flow. The invention is a superior method of drainage over conventional systems that employ pressure, vacuum, isolation valves and/or passive flow restrictors to achieve drainage of the separators. The embodiments are primarily directed to the fields of preparative supercritical fluid chromatography (SFC) and supercritical fluid extraction (SFE). An advantage of one embodiment allows the economical conversion of typical HPLC systems to state of-the-art supercritical fluid chromatography (SFC) systems with minimal modification to system components.

The flare line is operatively connected to the vent port and includes an igniter to burn gases before they are vented to the atmosphere. The sand trap and the separator can be used as conditions require to treat fluids from a well before the fluids enter the tank.

  • Patent number: 7959715
    Abstract: Various embodiments of the present invention are directed to limiting a presence of air bubbles in fluidic media in a reservoir. Air passages may allow air to escape from fluidic media in a reservoir. Membranes may allow for trapping air bubbles in fluidic media before fluidic media enters a reservoir. A membrane may allow air to flow from a first reservoir containing fluidic media to a second reservoir while plunger heads within each of the reservoirs are moved within the reservoirs. An inner reservoir with a membrane may be moveable within an outer reservoir to allow air to move from the outer reservoir to the inner reservoir. An inner reservoir containing pressurized gas may allow fluidic media to be transferred to an outer reservoir.

  • Patent number: 7935228
    Abstract: A process to reduce emissions discharged from a natural gas processing system wherein the processing system includes a glycol dehydrator for absorbing water, moisture and absorbable hydrocarbons, a reboiler for heating water rich glycol, a still column in communication with the reboiler and a reflux condenser. The process includes the steps of directing vapors and gases from the still column and reflux condenser to a condenser in order to condense vapors to liquid. The gases and liquids from the condenser are directed to a condensate separator in order to separate by gravity. Non-condensible vapors and water from the condensate separator are delivered to a vaporization chamber immersed in the reboiler. Water is re-vaporized into steam and permitted to mix with non-condensible vapors in the vaporization chamber. The steam and non-condensible vapors are inducted into a combustion zone in a firetube in the reboiler. The hydrocarbons in the vapors are combusted in the firetube.

  • Patent number: 7935179
    Abstract: A method and apparatus for exhausting gas from a coating material. The coating material is fed in the bottom part area of a drum (3) rotating around an essentially vertical axis inside a vacuum tank (1), whereby the rotating motion of the drum causes the coating material to rise up the inner wall of the drum and to discharge from the upper edge of the drum as a thin film against the inner wall of a vacuum tank, wherefrom the coating material flows downwards. The coating material is arranged to rise up the wall of the drum stepwise, so that the coating material will form a thin veil-like film on at least two different step levels (10-12), whereupon the gas bubbles in the coating material will break and be discharged from the coating material.
