The combination of booster-primary and hyper compressors reaches very high pressures in Low Density Polyethylene Plants. Pressure and flow pulsations due to the unsteady flow generate an acoustic energy that interacts with the mechanical system of the plant, causing mechanical vibrations. Pressure pulsation and vibration control on relatively high pressure piping is necessary to prevent failures caused by cyclic stresses due to both internal pressure fluctuations and vibrations generated by the compressor. To increase the compressor performance, safety and reliability designers require advanced methods of simulation to evaluate piping and compressor behavior during the initial stage of the project. The paper will investigate the modeling of the pulsation with the influence of fluid-dynamic aspect related to the gas and the relevant system interaction.
