  • Patent number: 8640529
    Abstract: An apparatus and method for down hole gas separation from the multiphase fluid flowing in a wellbore or a pipe, for determining the quantities of the individual components of the liquid and the flow rate of the liquid, and for remixing the component parts of the fluid after which the gas volume may be measured, without affecting the flow stream, are described. Acoustic radiation force is employed to separate gas from the liquid, thereby permitting measurements to be separately made for these two components; the liquid (oil/water) composition is determined from ultrasonic resonances; and the gas volume is determined from capacitance measurements. Since the fluid flows around and through the component parts of the apparatus, there is little pressure difference, and no protection is required from high pressure differentials.

  • Patent number: 6679096
    Abstract: A method measures the concentration of the partial pressure of gases, particularly oxygen, in fluids. Know methods for measurements under rough conditions, e.g., measurement of the oxygen partial pressure in grounds, dumps or in the ground water are completely unsuitable. In the present method as described, in the internal area of a hollow vessel closed off to the outside, whose wall consists at least partially of a gas-specific permeable synthetic material that is in contact with the fluid with its external side, the partial pressure change proportional to the gas concentration is measured as a time-scanning of pressure change or as a change of a pressure-dependent physical variable. The measuring principle is very simple and is particularly suitable for the determination and long-time monitoring of the oxygen concentration and of further gases and can also be used in problematic locations.

An increase of one or more detected chemical components signifies an actual or potential electrical problem with the equipment. The preferred apparatus consists of a gas extractor, an infrared gas analysis instrument, and a gas diaphragm pump. Gas and water vapor components are extracted from the insulating fluid by permeating through a membrane in a gas extractor. The gas and/or vapor components are then brought into an infrared gas analyzer by the gas diaphragm pump. A quad detector in the analysis instrument identifies and determines the concentration of three specified gases and/or the vapor simultaneously.
