本論文主要進行二氧化碳回收再利用之化工設計與整合，分別整合三個程序：(1) 二氧化碳回收轉製合成氣；(2) 合成氣製造甲醇及；(3) 甲醇轉製汽油。研究中並針對「甲醇轉製汽油」程序進行狹點技術與換熱器網路分析，吾人比較其熱能整合前後的能源需求以及成本花費，最後選擇出最佳方案。 論文中主要利用兩套軟體進行研究：“Aspen Plus” 與 “SuperTarget”。前者主要是用於程序合成、設計與模擬；後者則是進行狹點分析與換熱器網路合成。 In this thesis, we have presented a chemical process design and integration for the recovery and utilization of carbon dioxide. Essentially, it consists of three processes: (1) recovery and utilization of carbon dioxide and conversion to the making of synthesis gas; (2) methanol production from the syngas, and (3) production of gasoline from methanol. In the study, we have also carried out a pinch analysis and heat exchanger network synthesis for the “production of gasoline from methanol”. At last, we have compared the energy consumption and capital costs of the process with/without heat integration and selected the optimal case.
Two kinds of software were utilized in the research-Aspen Plus and SuperTarget. The former was used for the process synthesis, design, and simulation; the latter was used to carry out the pinch analysis and the synthesis of heat exchanger network.
