摘　　要：针对新型侧反应精馏集成技术生产醋酸甲酯的工艺生产过程,采用基于独立反应量的系统设计方法获取最佳的反应精馏集成结构与稳态模拟结果。针对最佳稳态工艺设计结构,在传统控制回路的设计基础上,进行醋酸甲酯质量分数与灵敏板温度多变量模型预测控制模块设计,并通过在Aspen流程模拟软件建立醋酸甲酯侧反应精馏动态流程模拟系统,验证控制方案的有效性。To obtain the optimum integrated structure and the steady-state simulation of SRC for methyl acetate production, the systematic design approach based on the concept of independent reaction amount is applied to the process of SRC for methyl acetate production. And based on the basic control loops is designed, multi-variable model predictive control modular with methyl acetate concentration and temperature of sensitive plate is designed. At last, SRC of methyl acetate dynamic simulation based on process simulation software Aspen is used to verify the effectiveness of the control scheme. The effectiveness of control structure is demonstrated by fluctuations in methyl acetate concentration and temperature of sensitive plate. The simulation results show good control precision, robustness and dynamic follow performance of the control scheme.
