摘要(中)

本研究主要目的在於突破傳統蒸餾方式，利用旋轉填充床產生的高重力場與加鹽效應來達到分離異丙醇及水共沸物。由實驗結果發現，只要所加入的鹽類適量，分離後的異丙醇莫耳組成可突破共沸點，此程序具有和共沸蒸餾相同的效果。除了以上效益外，還可改善一般蒸餾塔加鹽蒸餾容易使鹽結晶與堵塞的缺點。經由經濟評估證明高速旋轉填充床分離共沸物所需之耗能較傳統共沸蒸餾塔低，不僅可以改善傳統蒸餾塔在分離共沸物時，所需大量耗費能源的缺點，更可以大幅縮減設備體積。

摘要(英)

The purpose of this study is to try to find a new way to separate the binary azeotrope of isopropyl alcohol (IPA) and water. Instead of using the traditional distillation tower, we utilized the rotating packed bed, with the alias of Higee (high gravity), and checked the effects of separation by adding different amount of salt.
The results of experiments show that the salt addition with proper quantity can break the azeotropic point. This study essentially brings the same effect of that of the traditional azeotropic distillation. However, the economic evaluation has proved that the operation cost of Higee is lower than that of traditional distillation tower, because it is much less energy consuming. Therefore, we could say Higee is economically superior to the traditional distillation tower, both in energy saving and facility size reducing view of point.
