SIMULATORS FOR SUPPORT OF PROCESS AND PLANT MANAGEMENT

Process simulators are increasingly used for plant and process operation purposes. These simulators differ from those used in process design in the user interface. which is identical to the usual operator interface of distributed control systems. The progress of the numerical solution parallels the dynamic behaviour of the real process, and not that of the numerical procedure. The simulation-supported tasks of plant and process operation are: education of operators. training and instruction of operators, support of plant operation by interpretion of plant states and transitions and by helping to formulate operating instructions.These tasks, the available simulation concepts and examples are discussed in detail.
