  • Patent number: 8298407
    Abstract: Embodiments of the Gas Vent are comprised of a horizontal float assembly, and a vertical gas valve assembly. The horizontal float assembly is connected via a fluid connection to a surge tank or any other connection to the overall gas processing system. The horizontal float assembly is comprised of a housing; a horizontal float; a flange; a sight glass; one or more sight glass valves; a horizontal float lever arm; a vertical valve hinge arm, and a hinge. The housing of the horizontal float assembly is essentially a large hollow process vessel with various openings and fittings formed by the housing to accept the various devices and. The horizontal float is a large, hollow vessel that partially floats on top of any liquid contained within the horizontal float assembly. As the horizontal float rises and falls in conjunction allowing gas to vent as it is accumulated.

  • Patent number: 6736964
    Abstract: The apparatus for separating and measuring mixed fluids, specifically the separation of crude oil and water and the volumetric measurement of each of the mixed fluids using a mechanical portable device primarily involving a separation vessel, an adjustable float within the vessel which allows the fluid of less specific gravity to be released from the top of the separation vessel through an upper pipeline, the heavier specific gravity fluid to be released from the bottom of the separation vessel through a lower pipeline, with fluid volume meters on each of the pipelines to measure the liquid flowing through the respective pipelines, the apparatus presented as a portable unit transferable from one pumping device to another, allowing for an accurate measurement of the fluids being extracted by the pumping devices.
