In order to optimize the operation of reactive distillation plant, the content and characteristics of the optimization of reactive distillation process were analyzed. A set of effective optimization strategies was put forward. The typical process was established with the goal of economic benefit and the process constraints and quality And conversion rate constraints optimization mathematical model. MTBE device operation optimization analysis, can improve the annual economic benefit of 1.62%. The integrated optimization idea of reactive distillation process is put forward. Through the integrated optimization analysis of the lactic acid purification reactive distillation unit, the optimal design parameters of the process can be effectively identified and the annual economic benefit can be increased by 8.23%. The calculation results show that this model and its algorithm can be effectively used in the optimization analysis of reactive distillation. By optimizing the calculation can be significant economic benefits.
