The temperature control and the composition control for the production process was used to evaluated a method to control the quality of methyl ester production in a reactive distillation column. The optimum condition at steady state was selected as the base case condition for the control study by using Aspen Dynamic Simulation. In this work, two controller settings for PID controller of each control loop were based on the Zeigler-Nichol and the Tyreus-Luyben tuning formulae. The controllability and performance of both control structures were compared. The result shows that the control loop using the Ziegler-Nichols setting gave better control performance than the other using the Tyreus-Luyben setting. It also found that the control structure based on temperature control gives the same control performance as the other based on composition control, but less expensive and less complicated to implement.

Real Process

The development of mathematics model especially non-square open-loop dynamic model has grown rapidly since four decades. Because of the need of simplicity and accuracy, industrial world is demanding a dynamic mathematical model as simple as possible but it still can represent the whole real process. Therefore, to meet those needs, an open-loop dynamic model of methyl acetate production process by using reactive distillation column has been built. Feed ratio, reflux ratio and reboiler duty were chosen to be the manipulated variables to make a better performance rather than only reflux flowrate and reboiler duty. Methyl acetate fraction in distillate and water fraction in bottom were still be selected as controlled variables, so a non-square open-loop dynamic model was formed.
