摘要: 为了解决催化裂化油浆中固体催化剂颗粒脱除的难题,中国石化长岭分公司(简称长岭分公司)与湖南中天元环境工程有限责任公司联合开发了针对催化裂化油浆过滤处理的耐高温特种陶瓷膜及错流过滤处理技术,建立了100 kt/a的催化裂化油浆膜过滤装置,对该装置进行了工业标定和长周期运行情况分析,结果表明:该装置稳定运行14个月,膜过滤后的催化裂化油浆的平均收率高于85%,灰分(w)低于50 μg/g。该装置的长周期稳定运行,为催化裂化油浆下游产品高值利用奠定了良好基础。

Abstract: In order to removal the solid catalysts in FCC slurry, SINOPEC Changling Company and Hunan Zhongtianyuan Environmental Engineering Co.Ltd. has joint developed a special high temperature resistant ceramic membrane and cross-flow filtration technology for FCC slurry filtration, and established a 100 kt/a FCC slurry membrane filtration unit. The calibration and long period operation demonstrated that after 14 months operation, the average yield of FCC slurry after membrane filtration was over 85%, and the ash mass fraction was less than 50 μg/g. The long period stable operation of the unit layed a good foundation for high value utilization of downstream products of FCC slurry.
Key words: FCC slurry, membrane filtration, asphaltenes, ash, catalyst particle
