Abstract

The main objective of this project is to control the temperature of styrene reaction inside jacket reactor by manipulating refrigerant flow of jacket for the learning process of the process control course. Mathematical modelling inside the reactor and the jacket was carried out through moles and energy balances. The temperature control system was implemented using pneumatic valve, sensor-transmitter and dynamic simulation using SIMULINK. The proportional-integral controller reached steady state in a low time and the reaction temperature error was lower than that reached by the proportional controller. Also, the proportional-integral controller reacted fast to the step change in the set point of reaction temperature with a good performance. Likewise, the proportional-integral controller performed very well against a step change in the inlet temperature of polymer.
