    Optimizing production rate changes and abnormal situations of process plants induce a number of design and performance criteria for Advanced Process Control (APC). In addition to stabilizing control APC must also possess optimal performance within wide operating regions in capacity changes and abnormal situations with changing, preset criteria. This paper deals with the verification of APC against plant specific performance criteria utilizing a safe simulation environment with seamless co-simulation of two rigorous dynamic simulators. The presented simulation environment enables extended hard-testing of the APC capabilities to possess autonomous functionalities and to manage also involved environmental risks in abnormal situations. A refinery process furnace has been presented as a case study of the presented subject.
