• 中文摘要： 應用乳化液膜透過法,探討甲苯/對二甲苯混合物之分離。本實驗使用Saponin為界面活性劑,而以正己烷為提取溶劑。文中,吾人有系統地探討程序變數對透過率與分離的影響; 包括改變:進料組成,乳化程度,界面液與進料液之容積比,接觸時間,混合強度,界面劑用量,和系統溫度等。在單階分離操作中,所獲得之平均分離度(Separation factor)為2.4。羅尼氏分離值(Rony's extent of separation)亦利用來計算分離效果,以討論與一般常用之分離度(Separation factor)比較。發現,羅尼氏分離值之特點在於更能定量化表示分離的效應。
• 英文摘要： The separation of a mixture of toluene and p-xylene was studied through the liquid surfactant membrane permeation. Saponin was used as the surfactant and hexane as the permeates-receiving solvent. The permeation and separation were discussed systematically by varying composition of feed, extent of emulsification, ratio of volume of surfactant solution to volume of feed solution, contact time and mixing intensity, surfactant additive and temperature. The separation factor of 2.4 in average was obtained in a single permeation stage. Rony's extent of separation is also expressed and compared with the conventional separation factor. In contrast to the separation factor, the extent of separation is characterized not only by the quality, but also by the quantity of a separation.
