Description

technical field [0001] The invention relates to the field of purification of catalytic cracking oil slurry, in particular to an integrated device for viscosity reduction and desolidification of catalytic cracking oil slurry. Background technique [0002] Catalytic cracking slurry (FCCS) mainly refers to the uncracked hydrocarbons at the bottom of the main fractionation tower of the catalytic cracking unit. FCCS can be used as a raw material for the production of carbon black, rubber filler and needle coke, but FCCS contains a large amount of solid particles, and direct processing is likely to cause blockage of production device pipelines and equipment wear, so desolidification treatment is required before FCCS is used. The current desolidification treatment methods for FCCS mainly include gravity sedimentation, centrifugation, filtration, adding sedimentation aids, and electrostatic separation. Among them, the electrostatic separation method has been widely used in the deso...

AI Technical Summary

Problems solved by technology

Before electrostatic separation and desolidification, it is usually necessary to reduce the viscosity of the oil slurry, usually by heating or adding a viscosity reducer, but this method usually has a poor viscosity reduction effect, which affects the subsequent desolidification
