摘　　要：采用自建的动态静电分离试验装置,开展针对某炼油厂的催化裂化油浆的动态静电分离试验研究,考察静电分离时间、电压、温度等工艺参数对静电脱除效果的影响,并采用扫描电镜(SEM)、能谱分析(EDS)和X射线衍射(XRD)等方法对固体颗粒进行表征分析。试验得出优化工艺条件为:静电分离时间为120 min,电压12 kV,温度200℃。在此条件下经过两级静电分离,催化裂化油浆的固含量降低至50μg/g以下,固体颗粒脱除率高达99%,实现了油浆中固体颗粒的高效脱除,满足油浆高纯度净化要求。The dynamic electrostatic separation experiment research of FCC slurry in a refinery is carried out by using the self-built dynamic electrostatic separation experimental device.The influences of process parameters such as electrostatic separation time,voltage and temperature on electrostatic separation removal are investigated.The solid particles in the slurry are characterized by SEM,EDS and XRD.The results show that the optimal process conditions are as follows:the electrostatic separation time is 120 min,the voltage is 12 kV,and the temperature is 200℃.Under these conditions,after two-stage electrostatic separation,the content of solid particles in the slurry is reduced to below 50μg/g,and the removal rate of solid particles is as high as 99%.The high-efficiency removal of solid particles in the slurry is realized,which meets the requirements of deep purification of the slurry.
