Naphtha cracking center (NCC) produces several valuable resources such as ethylene, propylene, butadiene, which are used in most petrochemical plants. Naphtha feed is reacted in furnace and produced gas mixture is extracted. This hydrocarbon mixture should be separated in recovery processes that include a series of distillation columns, compressors, and a number of heat exchangers. Since it separates mixture feed using difference in boiling point of each component, a distillation column consumes a large amount of energy. Several researchers have made every effort to optimize the operation of distillation columns in real-time [1]. So the dynamic characteristics of a distillation column must be examined for that purpose. Dynamic simulation can also be applied to controller design, operator training system, fault diagnosis, etc. In this study, the dynamic process simulation is applied to design and tuning controllers for the cold recovery system.
