Abstract:

The properties and characteristics of FCC slurry and the necessity of solid removal treatment were introduced. The principles, characteristics and research progress of several purification technologies, such as sedimentation separation, centrifugal separation, electromagnetic separation and filtration separation were summarized. The industrial application results of inorganic membrane filtration, flexible material filtration and electromagnetic separation were analyzed and compared. The development of FCC slurry solid removal technology was analyzed from the aspects of technology advancement, economy and stability. The results showed that the application of inorganic membrane FCC slurry desolidation technology was the most, the running time was the longest, and the solid content of the slurry was less than 50 μg/g. The mass fraction of Al+Si was less than 15 μg/g, the purified slurry could meet the needs of blending heavy low sulfur marine fuel oil and producing carbon materials.

Key words: FCCU, slurry desolidation, filtration, industrial application
