在生產環氧氯丙烷時會產生含甘油的高鹽廢水，這些廢水需要經過多道程序的處理才能排放。本研究主要是在設計出將含甘油的高鹽廢水中移除鹽份的製程，並且回收有經濟利益的甘油。
目前已有一些針對生產環氧氯丙烷時所產生的廢水進行處理之專利出現，方法包括鹽酸洗滌法、醇萃取法、蒸發法等。本研究一開始嘗試專利所提供方法處理含甘油的高鹽廢水，實驗結果顯示使用濃鹽酸鹽析廢水並用過濾裝置將固體鹽分去除的方法有最好的除鹽效果，但需要再進一步處理酸性廢液。本研究提出兩種處理酸性廢液方法，第一種是先加水稀釋酸性廢液再進行蒸餾，但此方式會產生出多餘的鹽酸，第二種則是鹽析後直接蒸餾，此種方法並不會產生多餘的鹽酸，是目前最佳且經濟評估後廢水處理成本最低的方法。

High-salt waste water containing glycerol can be produced in the process of epichlorohydrin synthesis. It needs to be treated by a number of procedures before being discharged. This study is mainly to design a process to remove salt from high-salt waste water containing glycerol and to recover glycerol with economic benefits.
There are a number of patents for the treatment of waste water produced when producing epichlorohydrin, including hydrochloric acid washing, alcohol extraction, evaporation and so on. This study begins by attempting some methods given in patents and then provides a methodology for the treatment of high-salt waste water containing glycerol. The experimental results show that the best salt removal method is achieved by using concentrated hydrochloric acid to separate the waste water and then remove the solid salt by a filtration device. However, this method needs further treatment of acidic waste liquid. In this study, two methods of treating acidic waste liquid are proposed. The first is to dilute the acidic waste water and then distill it. However, this method can produce excess hydrochloric acid. The second uses direct distillation after salting out. This method does not produce excess hydrochloric acid. It is the best method with the lowest cost of waste water treatment method from economic evaluation.
