The operation of such reused acetic acid is actually a dehydration process by distillation. The mixture of acetic acid and water is considered to be a close-boiling point distillation. Industrial processes normally add another chemicals as entrainer for energy conservation. A steady-state simulation via Aspen Plus software based on energy consumption for the dehydration process of acetic acid using different entrainers is implemented in this study. Simulation results show that using isobutyl acetate as an entrainer can save larger energy than using other entrainers in this system. In addition, a rigorous dynamic model for the dehydration process of acetic acid based on the modular approach using artificial neural networks (ANN) as phase identification has been developed. Dynamic simulation has demonstrated that phase identification by the developed ANN model is in general consistent with the result of Aspen Plus for this multiphase and multicomponent process. 黃琦聰 2001 學位論文 ; thesis 110 zh-TW
