Acoustic Study of Gas Compressor Sound Power Spectrum for Gas Compression Station

SERVICE:

Sound Power Level Measurements of Gas Compression Equipment

DESCRIPTION:

Tech collected an array of sound pressure level measurements in May, 2015 along the vertical face of a 75-foot compressor stack using a manlift. The measurements covered multiple sections of the stack and the stack top exhaust from a CAT G3616 gas compressor engine. Measurements were converted to sound power levels, for both 1\1 and 1\3 octave bands, using ANSI Standard S12.56. Tech also measured the narrow- band spectrum of the compressor stack with 1-Hz resolution for the low-frequency range of 6 to 200 Hz. These data were supplied to the electric utility for use in engineering design for the plant.

Key Points

• Tech collected measurements of a compressor stack covering multiple sections of the stack and stack top exhaust.
• Using the measurements collected, Tech converted them to sound power levels and supplied all data for future design use.
