Simulation of a Vinyl Acetate Monomer (VAM) process design is developed in this work to allow testing of two advanced control strategies within the base PI control scheme Specifically, the two schemes focus on improving the control performance of the azeotropic distillation column A detailed steady‐state and dynamic analysis of the distillation column has been performed to provide insight into the control behaviour of the two composition loops The possible benefits from this type of study include production increase, safer operation and lower operating cost To the authors' knowledge, this paper represents the first time a ratio control scheme and a model predictive controller (MPC) have been applied to the VAM process and presented in the open literature Simulation results are presented to illustrate the effectiveness of the new control strategies
