摘要： An inlet valve system for a cylinder chamber of a reciprocating compressor and a method for unloading the inlet valve system are provided. The inlet valve system may include an unloader, a valve assembly including a cylindrical valve body circumferentially disposed about a central axis of the inlet valve system, and a control valve actuator including a control valve body circumferentially disposed about the central axis of the inlet valve system. A control valve passage of the control valve body may extend along the central axis of the inlet valve system, a control valve element may be disposed in the control valve passage, and a control pressure source may be fluidly coupled to the control valve passage.

摘要： A fluid distribution system (208) is provided for a reactor vessel (200) defining a reaction chamber (202). The fluid distribution system (208) may include a radial distribution component (224) positionable within the reaction chamber (202) and adjacent a vessel inlet (212) at an end portion of the reactor vessel (200). The radial distribution component (224) may include one or more annular distribution conduits (230) configured to receive a fluid mixture provided to the reactor vessel (200). The fluid distribution system (208) may also include an axial distribution component (226) positionable within the reaction chamber (202) to extend from the radial distribution component (224) along a longitudinal axis of the reactor vessel (200). The axial distribution component (230) may include a plurality of helical conduits (236) fluidly coupled with the one or more annular distribution conduits (230) and configured to receive the fluid mixture from the one or more annular distribution conduits (230) and to disperse the fuel mixture uniformly within the reaction chamber (202).

摘要： A hydraulic fracturing system that includes a fixed-speed gas turbine assembly having a gas generator and power turbine, both mounted to a semi-trailer. The system further includes a hydraulic pump mounted to the semi-trailer and connected to an output shaft of the power turbine and a hydraulically-driven fracturing fluid pump mounted to the semi-trailer and being in fluid communication with the hydraulic pump, the hydraulic pump supplying fluid pressure to the hydraulically-driven fracturing fluid pump. The system is configured such that the hydraulically-driven fracturing fluid pump receives fracturing fluid containing chemicals and proppants and pressurizes the fracturing fluid to a pressure sufficient for injection into a wellbore to support a hydraulic fracturing operation.

摘要： An internally-cooled diaphragm for an internally-cooled compressor is provided. The internally-cooled diaphragm may include an annular body configured to cool a process fluid flowing through a fluid pathway of the internally-cooled compressor. The annular body may define a return channel of the fluid pathway, and a cooling pathway in thermal communication with the fluid pathway. The return channel may be configured to at least partially diffuse and de-swirl the process fluid flowing therethrough, and the cooling pathway may be configured to receive a coolant to absorb heat from the process fluid flowing through the return channel.

摘要： A liquefaction system and method for producing liquefied natural gas (LNG) is provided. The liquefaction system may include a heat exchanger to cool natural gas to LNG, a first compressor to compress and combine first and second portions of a single mixed refrigerant from the heat exchanger, a first cooler to cool the single mixed refrigerant from the first compressor to a first liquid phase and a gaseous phase, and a first liquid separator to separate the first liquid phase from the gaseous phase. The liquefaction system may also include a second compressor to compress the gaseous phase, a second cooler to cool the compressed gaseous phase to a second liquid phase and the second portion of the single mixed refrigerant, a second liquid separator to separate the second liquid phase from the second portion of the single mixed refrigerant, and a pump to pressurize the first liquid phase.

摘要： A method is provided for fabricating a carbon nanotube metal matrix composite. The method may include forming a molten mixture by combining carbon nanotubes with a molten solution. The carbon nanotubes combined with the molten solution may be dispersed therein. The method may also include transferring the molten mixture to a mold and applying a magnetic field to the molten mixture in the mold to substantially align at least a portion of the carbon nanotubes with one another. The method may further include solidifying the molten mixture in the mold to fabricate the carbon nanotube metal matrix composite, where at least a portion of the carbon nanotubes may be substantially aligned in the carbon nanotube metal matrix composite.

摘要： A system and method for controlling the acoustic signature of a turbomachine having a plurality of valves wherein an operating load is identified and an arc of admission across a plurality of nozzles is associated therewith. A valve sequencing scheme is selected and implemented to activate the arc of admission for a particular operating load so as to minimize valve noise by adjusting valves simultaneously rather than consecutively.

摘要： A shaft of a compressor may include a first shaft section defining a first cavity axially extending therein and a second shaft section defining a second cavity axially extending therein. A plurality of inlet holes may be defined on an outer surface of the first shaft section, and a plurality of outlet holes may be defined on an outer surface of the second shaft section. The plurality of inlet holes may be in fluid communication with the first cavity and the plurality of outlet holes may be in fluid communication with the second cavity. The first cavity and the second cavity may form a passageway fluidly coupling the plurality of inlet holes and the plurality of outlet holes.

摘要： A clamping and support system for a turbine is disclosed. The clamping and support system may include a support bar coupled with a lower diaphragm portion of the turbine. The support bar may have a protuberance extending from a first end portion thereof that may at least partially extend into a slot formed in the lower diaphragm portion of the turbine. The clamping and support system may also include a clamping bar coupled with a second end portion of the support bar. The clamping bar may at least partially extend into a slot formed in an upper diaphragm portion of the turbine such that at least a portion of the lower diaphragm portion and at least a portion of the upper diaphragm portion are interposed between the clamping bar and the protuberance of the support bar, thereby coupling the lower diaphragm portion with the upper diaphragm portion.
