Application of Virtual Simulation Environment to Fluid Catalytic Cracking Unit Control Haruo TAKATSU* Takashi NOZAKI, Kenji OKADA** Abstract: This paper reports how to utilize a virtual simulation environment using a dynamic process simulator for the purpose of process operation and control system design in industrial production systems. It also aims for the integrated engineering environment including all process life cycle phases such as process design, engineering, implementation, and maintenance. Virtual simulation environment using rigorous model based dynamic simulator and multi-variable model predictive optimizing control covering large process unit has been developed and applied to the fluid catalytic cracking unit control. Effectiveness of the environment has been confirmed from the viewpoint of not only process engineering but also control engineering. Virtual simulation environment is also applicable to the evaluation of other operation and control systems. Keywords: Advanced Process Control and Optimization, Dynamic Simulator, Fluid Catalytic Cracking Unit, Modeling and Simulation I. INTRODUCTION From the viewpoint of plant life cycle management, primary industries such as petroleum refineries and petrochemicals have been shifting from the age of high-growth production to the age of stable-growth production. In the high-growth production age the mass-production cycle makes it possible to realize cost reduction and improvement of production efficiency resulting in a new subsequent investment. On the other hand, in the stable-growth production age the flexible amount production cycle is required to respond to rapid market demand changes and to shorten the product cycle of plan, design, production and sale, resulting in the acquisition of customer expectations. Furthermore, industrial societies have been facing with complex issues related to production activity. For example on the design of a production control system, not only key performance i
