Intake and exhaust manifold systems are integral parts of modern high-performance reciprocating engines, enabling major increases in efficiency, specific power output and emissions control. In contrast, the intake (suction) and exhaust (discharge) systems of compressors are generally an after-thought having the primary purpose of reducing pressure pulsations to tolerable levels. Compressor “manifold” systems reduce pulsations by adding damping that causes pressure losses, reducing the overall compression system efficiency. Improperly designed pulsation control systems increase the adiabatic horsepower required from the compressor cylinders, especially on higher speed compressors. Research over the last five years has explored the development of compressor suction and discharge systems that reduce system pressure losses, while simultaneously augmenting and increasing the compressor efficiency and specific flow output. Previous GMC papers have reported the results of computer simulation studies, lab testing, and field testing of reciprocating compressors with tuned performance augmentation networks (PANTM). Simulations and actual tests confirmed that properly configured PANs were effective in controlling compressor pulsations with very little system pressure loss. Field testing, in cooperation with El Paso Corporation, further confirmed that pulsation bottles, choke-tubes and orifices could be successfully eliminated from reciprocating compressor systems, replaced by PANs that demonstrated excellent pulsation control, acceptable vibration, and 60 to 80 percent less system pressure loss on low ratio, variable speed pipeline applications. While earlier papers reported PAN developments that utilized a combination of wye-branches and delay loops to control pulsations with reduced system pressure losses, this paper focuses on more recent research with advanced compressor manifold systems that (similar to modern high-performance engines) tune the entire compressor system to
