Abstract:	本論文主要分兩個案例，第一個案例為工業酒精，以乙烯直接水解方式製造酒精，分別使用苯與正戊烷兩種共沸劑，達到無水酒精純度與產量要求，並比較不同共沸劑之蒸餘曲線圖及其成本分析；其次，結合狹點技術，比較整合前後之能源消耗。第二個案例為纖維酒精，主要針對其純化之程序，先以側流式蒸餾產製粗製酒精，再以變壓吸附方式達到無水酒精所需純度99.5 wt%。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 the thesis, we have conducted two case studies for the production/purification of industrial ethanol and bioethanol, respectively. For the case of the industrial ethanol, we used a direct hydration process to accomplish the making of crude ethanol; then, we used benzene/n-pentane as an entrainer, separately, to achieve the dehydrated ethanol production with a 99.5 mol% purity. We also compare residue curve maps and cost of manufacture with these two different entrainers. In addition, we also combine the pinch technology in the study in order to compare energy consumptions with/without heat integration. For the case of the bioethanol—the production of cellulosic ethanol, we aim mainly at the purification stage by using a side-draw-distillation technique to manufacture the crude ethanol; then, we used pressure-swing-adsorption technique to achieve the dehydrated ethanol production with a 99.5 wt% purity. 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.
