炼油厂高浓度含酚碱渣碳化液萃取脱酚的研究1.脱酚萃取剂的开发

摘要

Based on comparison tests,a complex extractor,30% TBP kerosene solution with high extraction power and suitable to carbonized weak caustic ambient was selected.Under weak caustic conditions of pH 8.5,the percent of single-stage extraction dephenol is higher than 99%.%碱渣碳化液最突出的问题之一是酚的脱除。通过对比实验，选择了适合于碳化液弱碱性环境的高效、高萃取容量的络合萃取剂30% TBP煤油溶液。该萃取剂在pH值为8.5的弱碱性条件下单级萃取脱酚率仍高于99%。
