摘　　要：中国石油兰州石化公司炼油厂延迟焦化装置在正常生产过程中会产生5～8t／h的酸性水。该焦化装置酸性水中的焦粉含量（w）平均为0．2％左右。含有焦粉的酸性水易造成酸性水处理装置的塔盘沉积焦粉，使酸性水汽提装置由于塔盘堵塞而停工，影响全厂的酸性水处理。为解决酸性水携带焦粉问题，应用酸性水脱除焦粉技术对该装置进行了改造。装置改造后焦粉脱除率达到91％以上，解决了酸性水携带焦粉问题，保证了下游装置的长周期平稳运行。The delayed coker in Lanzhou Petrochemical Co. produces normally 5--8 t/h sour water with coke powder content （zv） about an average of 0.2%. The powder is easy to be deposited on the trays of the acid water treatment device, resulting in sour water stripper tray jam and suspension of the unit. In order to solve the problem, the acid water treatment unit was revamped by adopting a powder removal technique. The coke powder removal rate reaches more than 91% after the revamping, leading to a long period running of downstream device.
