碩士 === 國立成功大學 === 化學工程學系碩博士班 === 91 === By addressing both flowsheeting and scheduling issues, an integrated design method for the batch azeotropic distillation systems has been developed in this work. The design method can be applied in two stages. First, the optimal flowsheet (state-task network, STN) is synthesized with an integer program (IP). A mixed integer linear programming (MILP) model is then constructed accordingly for generating the optimal schedule. The implementation procedure of the proposed design approach is demonstrated with a series of case studies in this thesis. From the numerical results obtained in various examples, it can be clearly observed that the performance of a batch azeotropic distillation process can be greatly affected by the STN structure. Consequently, the importance of the proposed integrated design approach can be confirmed indirectly.
