本研究的目的在於純化乙二醇的分離程序設計,藉由使用適當之溶劑移除乙二醇中的雜質(1,2-丁二醇)。本文首先進行液-液相平衡與汽-液相平衡的量測,再由實驗數據訂定熱力學模式參數後,應用於此一分離程序的穩態模擬,最後以年度總操作成本為目標函數進行程序的最適化。
The objective of this work is to design a separation process for purification of ethylene glycol. By using proper solvent to remove the impurity, 1,2-butanediol, from ethylene glycol. In the first step, the liquid-liquid equilibrium (LLE) and vapor-liquid equilibrium (VLE) data were measured. Using the thermodynamic model with the parameters determined from experimental data, we conducted steady-state simulation for the potential process. Finally, total annual cost (TAC) was taken as the objective function for the process optimization.
