Abstract: A technique facilitates removal of heat. The technique involves moving a process fluid through a buffer tank which is combined with a heat exchange system. The heat exchange system includes a conduit carrying a coolant fluid which removes excess heat from a heat source. The conduit is routed to the buffer tank so that the cooler process fluid moving through the buffer tank is able to remove heat from the coolant fluid before it is routed back to the heat source for continued heat removal. In a well application, for example, a heat source, e.g. an electric motor, may be located on a transport vehicle and cooled by the coolant fluid. The heat transferred to the coolant fluid from the heat source is removed by routing the coolant fluid through the conduit associated with the buffer tank. This enables the cooler process fluid in the buffer tank to be used in lowering the temperature of the coolant fluid.

Abstract: Apparatus and methods for detecting pump defects in a pumping system comprising multiple pumps. Each pump includes a pump fluid outlet fluidly connected with the pump fluid outlet of the other pumps. Pump defects are detected by generating information related to fluid pressure fluctuations at each pump fluid outlet and determining harmonic frequencies from the information related to fluid pressure fluctuations for each of the plurality of pumps. The amplitude of the harmonic frequencies is indicative of a defective one of the plurality of pumps.

Abstract: Method for analyzing blending mixer performance is provided, which includes providing an apparatus for blending solid particles with a liquid composition, a rotating slinger, and at least one accelerometer positioned adjacent a rotating component for producing a signal that is proportional to an acceleration of the rotating slinger over a frequency range. A recorder for receiving and storing over a time interval the signal is in communication with the accelerometer. The recorded signals are converted to numeric values indicative of a vibrational amplitude of the rotating slinger over the frequency range, and harmonics from the numerical values are identified and used to determine the condition of the rotating slinger.

Abstract: Vessels including an enclosure having an outer perimeter and an interior space, a channel disposed in the interior space, a first port disposed on a surface of the first enclosure at or proximate to a first end of the channel, and a second port disposed on a surface of the first enclosure at or proximate to a second end of the channel, where the channel has a length greater than the shortest distance between the first port and the second port, and where the first port and the second port are in fluid communication with one another. In some cases, the length of the channel is greater than a length of the outer perimeter. Optionally, the vessel may have a second enclosure having an outer perimeter and an interior space with a second channel disposed in the interior space, a third port disposed on a surface of the second enclosure at or proximate to a first end of the second channel, and a fourth port disposed on a surface of the second enclosure at or proximate to a second end of the second channel, where the second port, the third port and fourth port are in fluid communication. In yet some other optional variations, the vessel further includes a plurality of enclosures each having an outer perimeter and an interior space, a channel disposed in the interior space, a port disposed on a surface of the enclosure at or proximate to a first end of the channel, and a port disposed on a surface of the enclosure at or proximate to a second end of the channel, where the channel has a length greater than a shortest distance between the ports, and the second port and the ports disposed on the surface of the plurality of enclosures are in fluid communication. The perimeter shape of the enclosure(s) may be any suitable shape, including, but not limited to, substantially circular, ovate or rectangular.

Abstract: An embodiment of a method of operating at least two pressure vessels to inject a particulate slurry into a high-pressure line, comprises a first operating cycle comprising: isolating a pressure vessel from the high-pressure line, introducing, under low-pressure conditions, particulate solids into the pressure vessel through a particulate solids inlet aperture, a second operating cycle comprising: providing high-pressure flow into the pressure vessel, and providing a high-pressure slurry flow from the pressure vessel into the high-pressure line. The method further comprises causing a pressure vessel to operate in the first operating cycle while operating a pressure vessel in the second operating cycle, and synchronizing switching a first vessel from the first operating to a second operating cycle and switching a second vessel from the second operating cycle to the first operating cycle such that at least one of the vessels is operating in the second operating cycle.

Abstract: A system and methodology facilitates the handling of oilfield material. The oilfield material is stored in at least one silo which enables use of gravity to feed the oilfield material to a blender or other suitable equipment. Each modular silo is transportable and may be engaged with a support structure via a pivot connection. Once engaged, the silo is pivoted to a raised, upright position on the support structure. The oilfield material is then moved to an interior of the silo, and gravity may be used to feed the oilfield material to a blender or other equipment in a controlled manner.
