| 摘要: | 本論文提供了乳化液膜批式分離有機物的數學模擬以預測其分離效率。模擬中假設薄膜相與萃取相之交界處及薄膜相與剩餘相之交界處呈相平衡狀態。在分離過程的一個短時間內，數學模擬中各相的體積及乳化球的半徑，均假設固定不變，以預測其分離效率，然後調整調整體積及半徑的變化，再預測下一個短時間內的分離效率，連續同此步驟到任何操作時間。本論文所提的數學模擬預測結果，和實驗數據相比較，相當吻合。
A mathematical model for analyzing the extraction of a solute from a mixture by a solvent through dispersed liquid membrane in batch process has been presented. The phase equilibrium between the membrane and the external continuous phases and the phase equilibrium between the membrane and the internal phases are assumed. For a very short time period, the volumes of each phases are assume constant for a very short period, then for the next short time period, the volumes of each phases are recalculated and adjusted. The calculation procedure can continue to any desired operating time. The theoretical results from this model are compared with experimental data. In general, this model gives reasonable representation of experimental data. |
