The purposes of this research are to make a steady state and dynamic process simulations and to analyse process dynamics as well as to calculate the performance of 1DOF IMC on re-refinery used oil distillation column control. The controller for this research is IMC (Internal Model Control), a model based controller. IMC structure used in this research is one degree of freedom-IMC, a type of controller that gives a very good response for set point change (servo problem). First step in this work is to set steady state and dynamic process simulations. Secondly, a simulation on 1DOF IMC controller having a set point change in tray temperature was carried out using software Simulink. Responses of 1DOF IMC on enriching temperature and stripping temperature show that the controller can give good responses for set point change. The integral absolute error (IAE) for 1DOF IMC for a set point change in the enriching temperature are 68.5 for enriching temperature response and 13.59 for stripping temperature response. For a set point change of stripping temperature are 68.12 for enriching temperature response and 35.48 for stripping temperature response respectively.
