Abstract

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
