摘　　要：采用催化裂化油浆柔性脱固(RSFF)技术在中国石化上海石油化工股份有限公司5 kt/a油浆脱固侧线试验装置上进行了油浆过滤试验。结果表明:侧线试验中脱固油浆产品收率为90%左右,脱固油浆中(Al+Si)质量分数为10μg/g左右,RSFF技术可有效脱除粒径小于1μm的颗粒;在过滤开始阶段,过滤压差快速上升,然后缓慢上升,压差拐点与进料量呈正相关关系;提高再生触发压差可有效延长过滤周期。基于上述试验结果,在茂名外联石化有限公司300 kt/a装置上进行了工业应用试验,结果表明,脱固油浆产品平均收率达到92%以上,脱固油浆中灰分为100μg/g以下,灰分脱除率达到98%以上。RSFF油浆脱固技术不需要大量物流循环,对设备磨损低,既适用于加工直接来自催化裂化装置的油浆,也适用于加工来自罐区的油浆甚至外购油浆。FCC slurry filtration test was carried out in the 5 kt a side-stream test unit using the remove solid flexible filter(RSFF)technique in Shanghai Petrochemical Corporation.The results showed that the yield of the de-solid slurry was about 90%and the mass fraction of(Al+Si)in the de-solid slurry was about 10μg/g.The particle size smaller than 1μm could be effectively removed by RSFF technology.In the initial stage of filtration,the filtration pressure difference rose rapidly and then slowly.The inflexion of filtration pressure difference had a positively correlation with the feed flow rate.Based on the above results,an industrial application test was carried out in a 300 kt/a unit of Maoming Wailian Petrochemical Company.The results showed that the average yield of the de-solid slurry was over 92%,the ash content in the de-solid slurry was less than 100μg/g,and the ash removal rate was about 98%.RSFF technology does not need a lot of material circulation and has low wear to equipment.It is suitable for processing slurry directly from FCC unit and even purchased slurry.
