Static and Dynamic Simulation of 1, 3 Butadien Distillation Unit

Dynamic behaviour of chemical, petrochemical and refinerie’s process parameters are very complex. Considerations of system dynamic behaviour with respect to the system disturbances are necessary for proper design of such processes. The study leads to the selection or justification of installing process control system. In the present research a dynamic and static simulation of 1, 3 butadien separation distillation trains were scrutnized with the aim of retrofiting the existing unit with the divided wall columns. Attention on the selection of thermodynamic model revealed that the use of Peng- Robinson thermodynamic model is appropriate. The dynamic behaviour showed insensesivity of purified butadien stream to the feed flow rate.
