  • Patent number: 10807019
    Abstract: A valve assembly to extract gas, and thereby recover the gas, to be used or remediated at the well, and as a corrective action for wells slowing flow due to ongoing gas pressure accumulating in the flow lines. The valve assembly includes a container and a valve member disposed in the container. The valve member having an upper portion that includes a stop. The assembly is in a closed state when the stop is in sealing communication with an upper vent opening in the container, and in an open state, allowing for the capture of released gas, when the stop is spaced from the upper vent opening. The stop is guided along a vertical travel of the valve stem which is controlled by the rise and fall of fluid within the chamber.

    Abstract: A degasifier includes a gas chamber, a degasification unit and a resistance applying unit. The gas chamber is separated from a liquid flow path by a transmission member capable of transmitting a gas dissolving in a liquid in the liquid flow path. The degasification unit expels the gas dissolving in the liquid from the liquid by discharging the gas in the gas chamber through a discharge path so that a pressure in the gas chamber is negative. The resistance applying unit applies an inflow resistance to atmosphere which flows into the discharge path so that the gas chamber is maintained at a pressure at which the liquid can be degasified at the time of the discharging by the degasification unit while the discharge path is open to the atmosphere at all times.
