Description

technical field

[0001] The invention relates to the technical field of purification treatment of oil slurry, in particular to an electrostatic separation device for removing solid particles in catalytic cracking oil slurry, a process and an oil slurry purification device. Background technique

[0002] Catalytic cracking oil slurry is a by-product produced by the catalytic cracking process. Because the catalytic cracking oil slurry contains a large number of solid catalyst particles, its utilization is greatly limited. For catalytic cracking oil slurry, refineries generally take countermeasures to reduce the oil slurry re-refining ratio and increase output of part of the oil slurry. For oil slurry dumping, many domestic refineries currently use it as a blending component of fuel oil. Although it effectively solves the problem of the actual outlet of oil slurry, the utilization rate of oil slurry is still relatively low. In addition, the solid particles in the catalytic crack...
