摘要：

介绍了焦油加工馏分洗涤脱酚的反应原理和工艺流程，对中性酚盐含酚量低的问题进行了分析，对洗涤原料质量、稀碱浓度、反应温度、分离界面等工艺指标进行了优化和调整，改进后洗涤质量明显好转，中性酚盐含酚量由原来的16.39%提高到21.79%，脱酚萘油平均含酚量降低了0.06%，销售价格增加了510元/t左右。

Abstract:

The reaction principle and process flow of distillate scrubbing dephenolization of tar processing are described. The problem of low phenol content in neutral phenolate is analyzed. The process indexes, such as quality of scrubbing raw material, diluted soda solution concentration, reaction temperature, separation interface etc. are optimized and adjusted. The scrubbing quality after improvement takes a favorable turn. The phenol content in neutral phenolate is raised from 16.39% to 21.79%; the average phenol content in naphthalene oil for dephenolization is reduced by 0.06%; the sale price is increased by approximate 510 RMB yuan/t.
