    Abstract: A pulsation control device, coupled to a reciprocating pump with either suction or discharge piping, and having a spherical or cylindrical interior chamber that includes a curved baffle with a pressure drop device, e.g. a choke, separating the interior chamber into two volumes, is disclosed. The pulsation control device forces fluid flow through the pressure drop device, which provides an effective fluid passage that is smaller than the fluid passage for one or both of the inlet to and/or the outlet from the interior chamber. Fluid entering the pulsation control device reacts with fluid contained within the volume thereof on both sides of the baffle. The baffle attenuates pressure pulses within fluid passing through the interior chamber and improves acoustic pulsation energy reduction. The pressure drop device dampens high frequency pulsation magnitudes of pressure pulses within fluid passing through the interior chamber.

    Abstract: A system, apparatus, and method for improving performance of a pressurized system having a natural gas reciprocating compressor pump. The sound attenuation device has a pipe having an outlet connected to one or more tuned loops, where each loop includes a junction that divides a flow into two pipes. Another junction reconnects the two pipes to an outlet pipe, where the outlet pipe of the loops is coupled to the former junction of the loops. The loop has an inlet coupled to the outlet of a reciprocating compressor cylinder. Between the branches one of the branches is longer than another branch by an amount equal to a wavelength within a range of wavelengths of vibrations propagating in a fluid discharged from the reciprocating compressor pumping system.

    Abstract: An apparatus for reducing pressure spikes in a fuel line having a shut-off valve is provided. The apparatus comprises a body housing a biasing member and a moveable separation member. The body has first, second, and third chambers. The first and second chambers are coupled to upstream and downstream sides of the fuel line, respectively. The third chamber is coupled to a return line. When the shut-off valve is open, the separation member is biased toward the first chamber and separates the first and second chambers. When the shut-off valve is closed, the separation member expands the first chamber and places it and the third chamber in fluid communication once the separation member has gained a significant speed. The expanded first chamber accumulates fuel and the third chamber accumulates and vents the fuel such that transient pressure spikes are reduced and unlikely to damage a turbine system.
