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.
