Since the dawn of the natural gas industry, pulsation in pipes has been a misunderstood problem. Because pulsation causes vibration, vibration causes fatigue, and fatigue causes potentially catastrophic failures, the accepted way to attenuate pulsation has been to dissipate its energy as quickly as possible with friction. Unfortunately, friction causes pressure loss which decreases compression efficiency. The long sought silver bullet is pulsation attenuation with negligible pressure loss.
The truth is that pulsation energy is valuable and should be conserved, not dissipated. Pulsation attenuation pipe networks (PAN) are carefully designed systems that cancel, interleave, and reflect pulsation energy to conserve almost all of it.
PAN systems have been field-proven to provide essential pulsation attenuation with negligible pressure loss.
