Through the GMRC research program, the Side Branch Absorber (SBA), an industry proven pulsation control device, was adapted for use at a novel location in the piping system. Efforts to control cylinder nozzle pulsations with minimal losses resulted in a very useful device called the Virtual Orifice (VO). The VO can be installed on both low-speed and high-speed compressors to replace any cylinder nozzle orifices that are consuming large amounts of horsepower. Installation of the VO on a gas transmission compressor has shown significant pulsation reduction and improved efficiency. Vibration reduction achieved with a VO installed was similar to that achieved with an orifice installed. Reciprocating compressor installations require a balance between pulsation control, compressor performance, and mechanical vibration. The VO offers a solution that more effectively manages the cylinder nozzle resonance, thereby maintaining the required system balance.
