  • Patent number: 10478749
    Abstract: An apparatus introduces a sample into a separation unit of a chromatography system with a mobile phase, including first and second mobile phase components. The apparatus includes first and second pump systems, and an injection unit. The first pump system provides the first mobile phase component, first and second portions of the first mobile phase component flowing through first and second branches, respectively. The second pump system provides the second mobile phase component, a first portion of the second mobile phase component flowing through a third branch. The injection unit receives a combined stream of the first portions of the first and second mobile phase components provided via the first and third branches, respectively, and injects the sample into the combined stream to form a sample-containing stream, which is subsequently combined with the second portion of the first mobile phase component to form a diluted sample-containing stream.

    Abstract: A gas separator on pipe structured to transport a liquid is provided. The gas separator includes a section of piping, located upstream of a pump, having an increased diameter which is in fluid communication with an overhead pocket. Fluid flow in the portion of the pipe having an increased diameter is at a slower rate than other portions of the pipe. The slower fluid speed allows entrained gasses to stratify and float to the top of the pipe whereupon the gas will flow into the pocket. Thus, the fluid downstream from the gas separator has a reduced amount of gas in the liquid flow.

  • Publication number: 20100212406
    Abstract: A system for rapid collection of large volumes of dissolved gases from groundwater pumps the water from a large-diameter passage through a small-diameter restrictor passage, and then into a flow-through collection chamber. The small-diameter passage causes a drop in the hydrostatic pressure of the groundwater traveling therein, causing spontaneous ebullition of gas bubbles, which are then collected in the collection chamber. A treatment station within the passages selectively alters the concentration of dissolved gases within the groundwater. Testing reveals that the gases are collected in proportion to their presence in the groundwater, and thus the system allows accurate quantification of concentrations of dissolved gas in groundwater. The system may beneficially be made easily portable, thereby allowing its use in the field, as well as in laboratory settings.

A mixed liquid/gas stream is obtained at the top. The mixed liquid/gas stream is then separated into a liquid stream constituting the treated aqueous phase, and an offgas stream enriched with said gaseous compound, where the mixed liquid/gas stream is later separated under vacuum by establishing a gas headspace between the liquid stream and the gas stream, and by aspirating the latter.

    Abstract: Carbon dioxide contained within exhaust gas is combined with bivalent metal ions such as calcium ions or the like in concentrated salt water to form precipitated calcium carbonate and then can be expelled out. Such an environmental friendly design is realized by a bottle upside down device with a bottle neck exit on a bottom. A piston inside the device can be elevated to a top portion to produce a near vacuum air pressure inside the device. All the brine, exhaust gas, and oxygen, ozone drawn together into the device can be accelerated to form, at least, precipitated calcium carbonate to reduce carbon dioxide contained within the exhaust gas. Chemical reaction is accelerated by a high voltage discharger below the piston and by flashing a portion of water to atomize the brine. A heater can heat up the near vacuum device to accelerate chemical reaction.

  • Publication number: 20100064892
    Abstract: A gas liquid separator system for a hydrogen generating apparatus includes a collection area for collecting liquid from the generated gases. To empty the collection area occasionally so that liquid does not build up and become entrained again in the dried gas, a vent solenoid is provided in communication with the collection area and a pump is used to create a vacuum periodically on the electrolysis cells. Such arrangement is used to open the liquid gas filter and possibly just the sump to atmosphere occasionally and vacuum generated to draw the liquid from the sump back to the electrolysis cells.

    Abstract: Apparatus (20) for removing gas bubbles from a liquid to be infused to a patient wherein a gas trap (42) is located at the upper end of a vertical column (38, 40, 40a) having a lower inlet (44) and an upper outlet (56). A bracket (39) supports the column above the patient, and a bubble-separator (46, 39a, 47, 66, 63), positioned between the inlet and the outlet, causes gas bubbles to move toward the column axis as they rise so that they are captured in the gas trap (42). Liquid to be de-gasified is supplied from a vertical level above the column outlet and is delivered through the side outlet (56) to the patient below.

  • Publication number: 20090101006
    Abstract: A water deaerating system and method are provided. The first end of an open-ended conduit is placed beneath the surface of a body of oxygen-rich water. The conduit extends into a housing and where the second end of the conduit resides at a location in the housing that is above the surface of the body of oxygen-rich water. A vacuum is applied to a spatial region defined within the housing above the location of the second end of the conduit. The oxygen-rich water is pumped through the conduit and exits the second end of the conduit to enter the spatial region of the housing. The oxygen-rich water descends through the housing due to gravity. The oxygen-rich water's descension is interrupted and the vacuum operates to remove oxygen from the oxygen-rich water so-descending to generate oxygen-depleted water.

  • Patent number: 7513937
    Abstract: A device and method for reconditioning oil or vaporizing volatile fluids from oil of internal combustion engines in order to extend the oil service life is provided. Such a device can include a housing which defines a substantially enclosed open chamber which can receive heated engine oil. An engine oil inlet, a vapor outlet, and a reconditioned oil outlet may be coupled to the housing. In addition, the disclosed oil reconditioning device may be free of direct heating or supplemental heating sources other than the intrinsic heat of the heated engine oil as it enters the open chamber. The reconditioning devices can be configured to introduce engine oil into the open chamber prior to contact with any interior surfaces. Separation of volatile fluids can be affected using either spraying or thin film. The reconditioned oil has a significant reduction in water and fuel content thus allowing for increased service intervals and increased useful oil life.

  • Patent number: 7384451
    Abstract: When a reaction liquid is passed through a gas-liquid separation pipe having a larger volume per unit length than the volume per unit length of a pipe, a headspace part into which gas can be released is formed above the gas-liquid separation pipe, and the byproduct gas generated by the reaction changes into bubbles, moves upward in the reaction liquid, and is continuously released from a gas-liquid interface into the headspace part. While the gas is removed in the gas-liquid separation pipe, the pressure of the headspace part is controlled so as to be constant by a pressure adjustment device.
