  • Publication number: 20190136650
    Abstract: A drilling rig site may include at least one tubular configured to be inserted into a wellbore at the drilling rig, at least one imaging device configured to detect a location of an end of the at least one tubular or a feature of the at least one tubular, and a processor receiving an input from the at least one imaging device and configured to calculate a distance between the end of the at least one tubular and another element, a diameter of the at least one tubular, or movement of the at least one tubular. A method for completing a drilling operation at a rig site, may include capturing an image of a tubular at a rig site, the tubular configured to be inserted into a wellbore at the rig site, detecting a location of an end of the tubular or a feature of the tubular from the image, and determining a diameter of the tubular, a distance between the detected end of the tubular and another element, or movement of the tubular.

  • Patent number: 10247643
    Abstract: System, method, and apparatus embodiments characterize potential air emissions during the pig receiver depressurization. The mass flow rate, pressure, and temperature of exhaust gas released from the pig receiver are ascertained using a mass flow meter, pressure gauge, and temperature gauge, respectively. A flow meter and control valve regulate flow of exhaust gas through a sampling line and into a grab sample collection train. The grab sample collection train includes grab sample containers (e.g., piston cylinders, double-ended cylinders, and evacuated canisters) that collect exhaust gas samples over a range of pressures. The exhaust gas samples are used to determine the concentrations of gas components in the exhaust gas over the range of pressures. These concentrations are interpolated and/or extrapolated to provide a concentration versus pressure curve for each identified component in the exhaust gas.

  • Patent number: 8940077
    Abstract: A method for indirectly monitoring and controlling an electrically resistive adsorption system. Adsorption of a predetermined adsorbate is conducted while indirectly monitoring electrical resistance of a unified adsorbent element. Breakthrough is predicted based upon the indirectly monitored electrical resistance and a previously measured mass loading relationship between the resistance of the unified adsorbent element and the loading of the unified resistance element with the predetermined adsorbate. Adsorption, regeneration and cooling cycles are controlled by a controller without any direct measurement of temperature or resistance of the element and characterizations of mass loading and temperature. Systems of the invention can have no sensors that contact the element, are in an adsorption vessel, and/or are downstream adsorption vessel.

  • Patent number: 8636829
    Abstract: The invention provides gas purification systems for the recovery and liquefaction of low boiling point organic and inorganic gases, such as methane, propane, CO2, NH3, and chlorofluorocarbons. Many such gases are in the effluent gas of industrial processes and the invention can increase the sustainability and economics of such industrial processes. In a preferred system of the invention, low boiling point gases are adsorbed with a heated activated carbon fiber material maintained at an adsorption temperature during an adsorption cycle. During a low boiling point desorption cycle the activated carbon fiber is heated to a desorption temperature to create a desorption gas stream with concentrated low boiling point gases. The desorption gas stream is actively compressed and/or cooled to condense and liquefy the low boiling point gases, which can then be collected, stored, re-used, sold, etc.
