於化工產業中，蒸餾程序為最為耗能之分離程序。於2003年中東戰爭開始後，國際油價即不斷上漲，造成化工產業之成本不斷攀升。因此各種節能之熱整合方式如多效熱整合、熱耦合組態等因應而生。本研究嘗試結合多效熱整合及熱耦合組態之優點設計一新式複合型(Hybrid)熱整合組態，同時達到總能耗下降及能源再利用之目標。
研究上，以IIp理想反應蒸餾程序及具回流較真實之DPC反應蒸餾程序作為範例，進行複合型熱整合組態與其他傳統熱整合組態之節能效益比較。穩態設計以Aspen plus做為模擬工具，動態響應之研究則是利用Aspen plus dynamics來進行。
穩態模擬結果顯示，複合型熱整合組態於節能及減少操作成本方面皆有最傑出之表現，兩程序之複合型熱整合組態分別能節能50.4%及35%。複合型熱整合組態也可消除再混合效應，但與熱耦合組態相比其第二座蒸餾塔冷凝器浪費之能源較少。與多效熱整合相比複合型熱整合組態可減少兩塔間熱傳所需之熱傳面積。動態模擬結果顯示利用一壓力補償控制架構即可消除產能調整及組成擾動之影響。

In chemical industry, distillation process is famous on its high energy consumption. The price of crude oil continuously increases since 2003 A. C.. The energy-saving methods such as multi-effect configuration, thermally coupled configuration have been widely studied in open literatures. In this research, the design and control of a hybrid heat-integrated configuration through the combination of multi-effect and thermally coupled concepts has been studied in IIp type of reactive distillation (RD) process to improve energy efficiency and reduce overall energy requirement simultaneously.
The ideal IIp RD process and the diphenyl carbonate (DPC) RD process are used to demonstrate the steady state design advantage and dynamic performance of hybrid heat-integrated configuration. The steady state simulation result shows both of the cases can save the most energy and annul operating cost than other configurations. Energy saving percentages for both cases are 50.4 % and 35 %, respectively. The remixing effect still can be eliminated by hybrid heat-integrated configuration and the energy waste in condenser of second column is lower than thermally coupled configuration. The additional energy transfer area in the heat exchanger is also smaller than multi-effect configuration. The dynamic simulation result shows the products of both cases can be maintained in their specifications during the throughput and composition disturbance.
