| 摘 要： | 为解决延迟焦化装置酸性水携带焦粉,造成下游酸性水汽提装置生产波动的问题,通过采用旋流分离技术进行改造,增上酸性水除焦粉系统,对酸性水中的焦粉进行脱除。改造实施后,酸性水中焦粉含量可由24.5~42.7mg/L降至2.13~2.75 mg/L,焦粉脱除率达到91%以上,酸性水浊液中焦粉含量达到463~713 mg/L,焦粉脱除效果良好,脱除焦粉后的酸性水减小了对酸性水汽提装置的影响,达到了预期的效果。

TECHNICAL APPLICATION OF REMOVING COKE POWDER WITH HYDROCYCLONE FROM SOUR WATER IN DELAYED COKING UNIT |
| |
| Abstract: | The coke powder carry-over with sour water in delayed coking unit could result in production fluctuation on the downstream sour water stripping unit. In order to solve the prob-lem , coke powder removing system of the sour water was added by using hydrocyclone separation technology. The content of coke powder in sour water was decreased from 24. 5~42. 7 mg/L to 2. 13~2. 75 mg/L and the removal rate of coke powder was more than 91%, the content of coke powder in sour water emulsion reached 463~713 mg/L and the removal effect was good. Effect of the sour water after removing coke powder on the stripping unit was decreased, and the expec-ted purpose was obtained. |
