Description
Technical Field
The utility model relates to a petrochemical field, concretely relates to slurry oil coagulation ware that can be arranged in catalytic cracking slurry oil catalyst granule to subside.
Background
The FCC slurry oil is unconverted hydrocarbon with a boiling point of more than 350 ℃ generated in the catalytic cracking process, has extremely special properties, is rich in colloid and asphaltene, has the characteristics of high viscosity and high density, has good economic value, but has great limitation on economic scale and value-added utilization because the FCC slurry oil contains 2000-9000 ppm of catalyst solid powder. The concrete aspects are as follows:
1. when catalytic slurry oil is used as a blending component of heavy fuel oil, if the catalytic slurry oil is not purified, catalyst solid powder in the slurry oil can cause the nozzle of a heating furnace to be worn, so that the problems of serious ash deposition on the surface of the heating furnace tube, reduction of heat efficiency, increase of energy consumption and the like are caused;
2. oil slurry is an important raw material source for carbon black production. Statistically, more than 50% of the world's carbon black feedstock (CBO) is FCC slurry oil. CBO ash (ASTM D-482) requirement of 500ppm, premium ash index of 300ppm or 200 ppm;
3. the slurry oil is a high-quality raw material for delayed coking, can further improve the light-weight rate of crude oil processing as a coking raw material, and more importantly, can be used for producing needle coke for preparing a graphite electrode. The ash content of the oil slurry must be reduced to below 500 ppm;
4. the sources of the raw materials for residue hydrocracking are wide. When the catalytic slurry oil is used as a raw material in a residual oil hydrocracking process, the ash content of the slurry oil must be reduced to be below 500ppm, otherwise, the catalyst powder carried in the slurry oil can cause the blockage of hydrogenation catalyst holes, the increase of pressure drop, the inactivation of the catalyst and the like;
5. the catalytic slurry oil is rich in heavy aromatics more than 60%, and the heavy aromatics are ideal fillers for rubber and plastic processing after solvent extraction. However, the presence of the catalyst powder causes troubles in the operation of the extraction column and in the recovery of the solvent.
It is well known to those skilled in the art that to make full use of the FCC slurry oil, the catalyst solids must be removed from the slurry oil as much as possible.
The existing technology for removing the catalyst solid powder comprises the following steps: natural settling method, assistant settling separation method, filtration method, electrostatic separation method, centrifugal separation method, etc. Except for the industrial application cases of the chemical assistant settling separation method and the filtration method, no industrial application cases exist in other methods.
