Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A method for boosting a multiphase fluid is provided. The method may include separating the multiphase fluid into a liquid phase and a gaseous phase in a separator, compressing the gaseous phase in a compressor, and discharging the compressed gaseous phase from the compressor to the discharge line. The method may also include draining the liquid phase from the separator to a liquid reservoir, passively actuating an inlet control valve to flow the liquid phase from the liquid reservoir to a liquid tank, and actively actuating an inlet actuation valve to flow a motive gas from the compressor to the liquid tank to thereby pressurize the liquid phase contained therein. The method may further include passively actuating an outlet control valve to discharge the pressurized liquid phase from the liquid tank to the discharge line, and combining the compressed gaseous phase with the pressurized liquid phase in the discharge line.

Abstract: Methods for retrofitting a turbomachine are provided. A first trip cup of the turbomachine may be replaced with a second trip cup. The first trip cup may include a throw-out arm connected to a first trip cup spring. The second trip cup may include a plunger disposed in a hole defined by the second trip cup and a plunger spring encircling the plunger in the hole. The first trip cup may be removed from the turbomachine and the second trip cup installed such that a location of the plunger in the turbomachine is the same as a location of the throw-out arm in the turbomachine when the first trip cup was installed on the turbomachine. The tension in the plunger spring may be adjusted such that, when a speed of the turbomachine exceeds a predetermined value, the plunger actuates a trip paddle located adjacent the second trip cup.

Abstract: A sealing system for process gas leakage from a turbomachine casing is provided. The sealing system may include a seal assembly housing coupled to or integral with the turbomachine casing. The seal assembly housing defines a bore configured to receive a rotary shaft and a sealing assembly. The sealing assembly includes a plurality of carbon rings mounted circumferentially about the rotary shaft. The plurality of carbon rings may include an inboard carbon ring configured to prevent flow of a separation gas inboard of the barrier seal, an outboard carbon ring configured to prevent flow of contaminates into the seal assembly housing, and an intermediate carbon ring interposed between the inboard carbon ring and outboard carbon ring. A pressure differential is maintained across the inboard carbon ring, such that the separation gas is prevented from flowing inboard across the inboard carbon ring by a residual portion of a seal gas.
