介绍分浓度水洗促进剂CBS工艺：通过对促进剂CBS半成品离心脱水得到的母液按照高、低浓度分别存放，分类使用；高浓度母液在蒸馏釜蒸馏回收环己胺，低浓度母液进行二次利用，代替部分工艺水水洗半成品。采用分浓度水洗工艺，生产1 t促进剂CBS的洗水用量可减小2~3 m3，废水处理费用降低，效益提高。

The washing process of accelerator CBS was improved by fractionation method. The semi-ifnished product was separated by centrifuge into high concentration part and low concentration part. The one with high concentration was then further processed by distillation and the solvent, cyclohexylamine, was recycled. The one having low concentration was used as part of the washing water. With this improved process, the water consumption was reduced by 2~3 m3 for 1 t production of CBS. Thus the waste water treatment cost was reduced, and the proiftability was improved.
