Abstract
AbstractBACKGROUNDControlling the behavior of processes for the recovery of ethyl acetate and isopropanol from industrial wastewater is a hot topic. In this work, dynamic control structures of the extractive distillation process and heat pump combined with feeding preheating extractive distillation process are researched. The control performance of the proposed control structures is tested by adding feed flow and composition disturbance. In these two processes, two‐point temperature control structure is first used.RESULTSThe results show that this structure can maintain product purity within a reasonable range under disturbance. Furthermore, the composition controller is used to improve control performance.CONCLUSIONThe improved structure can effectively meet the requirements of product purity. The heat pump combined with feeding preheating extractive distillation process can use the same control structure as the extraction process and show good controllability. This study has a certain guiding value for the research of chemical dynamic control. © 2021 Society of Chemical Industry (SCI).
