本研究採用熱凝聚酵母菌Saccharomyces diastaticus LORRE-316作為酒精醱酵程序的生產菌株，進行一系列的醱酵程序分析與整合。我們分別探討連續醱酵程序和含菌體迴流連續醱酵程序；在不同基質濃度之醱酵的分析，探討質能整合與回收再利用以提高整個程序之效能。本研究的酒精分離與純化部份是，採用蒸餾塔與分子篩等單元，以得到可使用標準的生質酒精。本研究之程序是利用SuperPro Designer軟體來建構，接著分別進行各種整合程序的質能計算，以得到各別的設計結果，並且評估醱酵分離程序的質能利用與效能評估，希冀能找出最佳的整合連續式菌體迴流酒精醱酵程序。

We perform a series of analysis and integration of the bioethanol fermentation process with a thermo self-flocculating yeast, Saccharomyces diastaticus LORRE-316, in this thesis. We discuss these analyses of the continuous ethanol fermentation process, the continuous ethanol fermentation process coupled with cell recycling, and fermentation by different substrate concentrations separately. In order to get the standard ethanol fuel and normalization process, the treatments in the CO2, DDGS (Distillers Dried Grains with Solubles), and ethanol purification used the same settling and unit procedure in this research. These processes of this research are constructed by SuperPro Designer software, and carry out the calculation of various kinds of processes respectively, in order to gain each design result specifically. To evalutate the integration and optimization of the continuous ethanol fermentation process coupled with dell recycling, we assessing the utilities of mass and energy and the process efficiency.
