Dynamic system analysis is fundamental to study and optimize the overall behavior of an industrial plant. Centrifugal compressor trains are generally exposed to risk of surge and require adequate protection through dedicated control systems. These one shall be designed to meet normal operating - as well as transient - conditions. Possible process plant modifications may be identified by the outcomes of the analysis. To this purpose CST performs full plant dynamic simulation studies focusing on key risk areas: compressors, drivers, piping system, control valves, and control system.
