Sažetak
During 2016 large-scale project with the aim to provide monitoring, analysis and tuning of more than 350 control loops at the Rijeka Refinery process units was carried out. Control loop audit included diagnostics of the field instrumentation and control valves, define sources of variability and oscillation, and poor control loop performance. The analysis was the foundation for control loops optimization which resulted with decreased number of control loops in manual mode, reduced variability of controlled variables and more stable operation.
