摘要
为解决氨法精制直馏柴油使用乙醇作破乳剂时，存在乙醇用量与损耗大、溶剂和油比例高以及溶剂再生能耗高等问题，使用前期工作已开发出的SW－1破乳剂，考察氨法精掉的最佳的实验室操作条件。试验结果证明，SW-1破乳剂能满足氨法精制直馏柴油的防乳化要求，与使用乙醇破乳剂时相比，该工艺溶剂循环体积下降58．3％～75．0％；产品（氨精制柴油）酸度0．21mgKOH／100mL，无水分、氨、水溶性酸碱，钢片腐蚀合格，质量满足产品指标要求，优于碱洗电精制柴油。
Alcohol is normally used as the demulsifier in ammonia treating of straight－run diesel oil， which has the disadvantages of high dosage and consumption of solvent as well as the high energy consumption In solvent recovery． A newly developed demultifier named SW－1 was tested in the laboratory． The test result showed that SW－1 ean fulfil the demulsifying requirement． In comparison with alechol， the recycle volume of the demulsifier decreases by 58． 3％ to 75． 0％， the quality of the treated oil， including low acidity， free of water， ammonia and water soluble acid＆alkali， and qualified copper strip test， etc， meets the diesel oil specification and is better than the diesel with caustic washing．
