Abstract: The present disclosure provides backup systems for air compressors. The systems can detect an air compressor failure and/or low instrument air pressure and activate a backup inert gas power source to maintain functionality of compressed air-powered pneumatic devices at a wellsite. The backup systems can provide a working fluid in the form of an inert gas to the compressed air-powered pneumatic devices.

Abstract: The present disclosure provides systems and methods for converting a pneumatically controlled separator system, such as a liquid-gas separator system, to a separator system having electrically actuated controllers, pumps, and valves. The electrically actuated separator system of the present disclosure meets emissions standards and reduces (or eliminates) methane emissions that are harmful to the environment. The electrically actuated components of the system of the present disclosure may be powered with solar energy, which also reduces (or eliminates) carbon dioxide emissions.

Abstract: A valve stem lifter assembly which operates to alternatively open and close a valve, includes a rotatably mounted rotary shaft having a top end axially aligned with a riser with a rigidly connected pull shaft and an opposite end axially aligned with an operator for selectively producing rotational movement of the rotary shaft and corresponding axial movement of the riser and pull shaft. The rotary shaft is rotatably connected to the riser by radius set screws positioned horizontally in the grooves of the rotary shaft. A plurality of guide shaft rods passing through the riser interconnects the riser to the valve stem lifter assembly to prevent axial separation of the riser and rotary shaft, and rotation of the riser, while permitting free relative rotation of the rotary shaft and axial movement of the riser and pull shaft.

Abstract: The present disclosure provides systems and methods for determining, in real-time, emissions savings. The systems and methods are configured to determine emissions savings achieved by converting natural gas-powered pneumatic control systems to compressed instrument air systems. An amount of methane and/or carbon emissions savings is determined by calculating, in real-time, the amount of compressed air used by a pneumatic system and converting the amount of compressed air into an equivalent amount of methane and/or carbon emissions that would have been emitted into the atmosphere had the pneumatic system been operated by natural gas and/or electric power.

Abstract: A valve stem lifter assembly which operates to alternatively open and close a valve, includes a rotatably mounted rotary shaft having a free end axially aligned with a pull shaft and an opposite free end axially aligned with an operator for selectively producing rotational movement of the rotary shaft and corresponding axial movement of the pull shaft. The rotary shaft is rotatably connected to a valve riser element by radius set screws positioned axially in the grooves of the rotary shaft. A plurality of guide shaft rods interconnects the riser to the valve stem lifter assembly to prevent axial separation of the riser and rotary shaft while permitting free relative rotation of the rotary shaft and linear movement of the pull shaft.
