  • Patent number: 11795776
    Abstract: This disclosure includes manifolds, subsea valve modules, and related methods. Some manifolds and/or subsea valve modules include one or more inlets, each configured to receive hydraulic fluid from a fluid source, one or more outlets, each in selective fluid communication with at least one of the inlets, and one or more subsea valve assemblies, each configured to selectively control hydraulic fluid communication from at least one of the inlets to at least one of the outlets, where at least one of the outlets is configured to be in fluid communication with an actuation port of the hydraulically actuated device.

  • Publication number: 20220412251
    Abstract: Typically, an engine-compressor for compressing natural gas for use as a fuel has a single cooling circuit to cool both its combustion unit and compression unit. A single cooling circuit design is not ideal because the optimal temperature for the combustion unit is higher than the compression unit of the engine-compressor. The present invention provides a dual zone cooling system to cool the combustion unit separately from the compression unit.

  • Patent number: 11346335
    Abstract: Most multistage compressors specify a maximum inlet pressure that may be supplied to the compressor to stay within designed limits. If the supply gas to be compressed is at a higher pressure than the specified maximum inlet pressure, then its pressure must be reduced before connecting it to the compressor. This pressure reduction is inefficient. The present invention avoids reducing the inlet pressure by routing the supply gas directly to the appropriate compression stage depending on its inlet pressure such that the compressor loads are still within the specified limits of the equipment.

  • Patent number: 10968867
    Abstract: When a natural gas compressor completes its compression cycle, residual pressurized natural gas remains in the cylinders, valves, and conduits of the compressor. Gas leaks into the environment increasing greenhouse gas emissions and introducing safety concerns. The systems and methods herein provide ways for substantially reducing or eliminating leakage of natural gas to the atmosphere while the system sits idle between compression cycles.

  • Publication number: 20210095614
    Abstract: An apparatus includes a valve and an actuator. The valve has a portion movably disposed within a valve pocket defined by a cylinder head of an engine. The valve is configured to move relative to the cylinder head a distance between a closed position and an opened position. The portion of the valve defines a flow opening that is in fluid communication with a cylinder of an engine when the valve is in the opened position. The actuator is configured to selectively vary the distance between the closed position and the opened position.

  • Patent number: 9316178
    Abstract: This application concerns systems and methods for compressing natural gas with an internal combustion engine. In a representative embodiment, a system for compressing a gas comprises a reciprocating internal combustion engine including at least one piston-cylinder assembly comprising a piston configured to travel in a cylinder and to compress gas in the cylinder in multiple compression stages. The system can further comprise a first pressure tank in fluid communication with the piston-cylinder assembly to receive compressed gas from the piston-cylinder assembly until the first pressure tank reaches a predetermined pressure, and a second pressure tank in fluid communication with the piston-cylinder assembly and the first pressure tank. The second pressure tank can be configured to receive compressed gas from the piston-cylinder assembly until the second pressure tank reaches a predetermined pressure.

  • Publication number: 20120107921
    Abstract: Embodiments of the present invention include model-based controls to control photobioreactor operation and the growth of algae for use as a biofuels feedstock. In some embodiments, the model-based control can accounts for future conditions such as weather, product pricing, customer demands and/or other variables to operate the reactors in a manner that optimizes product revenues, minimizes costs or energy, maximizes photosynthetic or energy balance efficiency, and/or any combination of the aforementioned factors.
