本研究之目的為探討熱耦合節能設計之碳酸二苯酯反應蒸餾程序之製程設計與控制。在商業化製程中，一般以光氣法來進行合成碳酸二苯酯，然而光氣法容易造成設備損害及環進汙染等問題。而本研究將以低汙染的碳酸二乙酯與乙酸苯酯作為反應物，經轉酯化後生成碳酸二苯酯及副產物乙酸乙酯。
一般未經熱耦合之蒸餾系統內常存在著容易造成熱負載量上升之再混和效應，而熱耦合設計可以避免或減少再混和效應的發生。本研究先以不同過量反應物設計兩製程，藉由改變兩製程之內部設計規格並以最低之低年總成本為基礎，最適化兩不同設計。緊接著以蒸餾塔內組成分佈中找尋發生再混合效應發生之區域，並以熱耦合設計的方式減低或移除再混和效應，最後再比較兩不同過量設計之最低年總成本。經由熱耦合設計節能設備後，過量乙酸苯酯設計相較於過量碳酸二乙酯設計能省下將近6.7 % 的年總成本。
在動態控制策略上，庫存環路採取基本之設計，品質控制環路方面，先以靈敏度分析找出相關單元之敏感板，以不同的操作變數控制敏感板溫度以維持產品出料規格，最後再給予不同產能擾動與進料組成干擾，以判斷控制環路之可行性。

The purpose of this research is studied the designing and controlling of diphenyl carbonate (DPC) process by using diethyl carbonate (DEC) and phenyl acetate (PA) through the reactive distillation (RD) with thermally coupled arrangement. The NRTL and power law is used to describe the thermodynamic and kinetic model. Two type of excess reactant designs are discussed for finding the minimum total cost (TAC). On the other hands, thermally coupled arrangement can reduce the total energy by eliminating the remixing effect. By observing the mole fraction profile, the remixing effect can be found between RD and separation columns. The total heat duty may be greatly decreased by eliminating the remixing effect. Based on the original RD configurations, two thermally coupled cases have been studied in this research.
After adding the thermal coupling and reducing the total heat duty, the lowest TAC will do the dynamic simulation and control. The product can be maintained the specification by temperature controller scheme when the ±10 % throughput and -5, -10 % composition disturbance.
