Plantwide control structures design of methyl acetate process

Abstract

Methyl acetate is a fast-evaporating chemical component with many uses as solvent. For its production, methanol is first dehydrated to dimethyl ether and then carbonylated to methyl acetate. For a plant which carbon monoxide available, this may be workable. The two sections of the plant, dehydration and carbonylation section are separately considered. Therefore, the plantwide control strategy is considered for the entire methyl acetate process including two sections above. The control design methodology, wongsri is applied to the plantwide control structures design for reach the control objectives and effectively operating large disturbances in production rate and fresh feed compositions. A commercial process simulator achieves the dynamics simulation of this research, both of steady-state and dynamics conditions.
