Abstract: Effective use of catalytic cracking slurry resources has been a great problem for the refinery enterprise. It has become a common practice to send catalytic cracking slurry to coking unit for blending. As the increasing demand for heavy marine fuel oil with low sulfur content, SINOPEC Zhenhai Refining & Chemical Company has built a new set of 0.2 MM TPY catalytic slurry solids removal facility in order to reduce the low sulfur heavy bunker fuel cost of blending. It usesd inorganic ceramic membrane filtration technology to purify catalytic slurry. The purified slurry can be directly mixed with low sulfur heavy marine fuel oil according to the sulfur content or sent to the residue hydrogenation unit of the fluidized bed, and the concentrated slurry is sent to the coking unit. Inorganic ceramic membrane filtration technology has been successfully applied in industrial practice.
