Compressor stations where both centrifugal and reciprocating compressors operate can exhibit operational problems due to low frequency pulsations. Avoiding these problems requires an understanding of the mechanisms that generate the pulsations, the transmission and attenuation of the pulsation, as well as their effect on the operation of the centrifugal compressor and the accuracy and reliability of flow measurements. The pulsation frequencies in question are typically lower than vortex shedding frequencies and blade passing frequencies. This paper will provide insight into the mechanisms and effects of pulsations and will describe approaches to avoid them.
