This paper presents an optimization method for reactive distillation （RD） equipment. The method is based on a mathematical model of the reactive distillation equipment which includes an objective function and a constraint function accounting for the product quality and the reaction conversion. The objective function for the profit was increased by 1.62% in the optimization process for MTBE （methyl tert butyl ether）. The reactive distillation process was also optimized for lactic acid purification with the obiective function for the profit increased by 8.23%. The results illustrate the effectiveness of the reactive distillation optimization process and that considerable economic benefit cart be achieved by optimization.
