摘　　要：热泵辅助反应分隔壁精馏塔(HP-RDWC)将热泵技术与反应分隔壁塔相结合,集成了两种过程强化技术的优势。但由于HP-RDWC具有强耦合性和强非线性等特点,其控制方案的设计一直是研究重点之一。以HP-RDWC生产乙酸甲酯过程为研究案例,基于稳态过程的可控性指数筛选出兼具稳定性和鲁棒性的基础控制结构,为HP-RDWC的工业应用提供理论基础。Heat pump assisted reactive dividing wall column(HP-RDWC) is the integration of heat pump technology and reactive dividing wall column, which simultaneously has the advantages of both process intensification techniques. However, due to the strong coupling and nonlinear characteristics, the research of HP-RDWC is still insufficient in terms of control and operation. In this paper, the process of producing methyl acetate in a heat pump assisted reactive dividing wall column was taken as a study case. Based on the controllability index of steady-state process, the basic control structure with stability and robustness was selected, which would help promote the industrial application of HP-RDWC.
