反应蒸馏的最新进展使人们对许多酯化过程的设计/再设计重新产生了兴趣。对于乙酸戊酯的酯化，存在提供从常规再循环结构到反应蒸馏的逐渐过渡的设计替代方案。四元混合物的相行为立即排除了常规循环结构的可能性，并且在这项工作中，我们探索了两种不同配置的设计，耦合反应器/塔和反应蒸馏塔，用于乙酸戊酯过程。年总成本（TAC）用于评估不同设计的经济优势。系统的设计程序被设计为耦合反应器/塔系统，以及反应蒸馏过程。结果清楚地表明了反应精馏在乙酸戊酯生产过程中的经济优势。乙酸戊酯工艺的独特之处在于具有显著的双液区和高纯度水。
Recent advances in reactive distillation have led to renewed interest in the design/redesign of many esterification processes. For the esterification of amyl acetate, design alternatives exist that offer a gradual transition from the conventional recycle structure to reactive distillation. The phase behavior of the quaternary mixture immediately excludes the possibility of the conventional recycle structure, and in this work, we explore the designs of two different configurations, a coupled reactor/column and reactive distillation column , for the amyl acetate process. The total annual cost (TAC) is used to evaluate the economic advantages of different designs. Systematic design procedures were devised for the coupled reactor/column system, as well as for the reactive distillation process. The results clearly indicate the economic advantage of reactive distillation for the amyl acetate process. Unique characteristics of amyl acetate process include a significant two-liquid zone and high-purity water from ...
