Please discuss the technologies for separating solids from catalytic cracking slurry
Thread Content
Please, experts, discuss the technologies related to the separation of solids from catalytic cracking slurry: including the techniques for using slurry filters； Application technology of slurry solids sedimentation agents. In particular, the solid separation technology for catalytic cracking slurry that produces large amounts of propylene? Thank you! :handshake :handshake :handshake
Is my question too simple? Why is no one paying attention to me? :'( :'( :'(
Oil slurry filters are widely used and seem to work fairly well. However, when the production of propylene increases, the density of the oil slurry rises significantly, and the amount of solids in it also increases, which poses challenges to the long-term, stable operation of these filters. Therefore, it is possible to store oil slurry with a high solid content in separate storage tanks, allowing the solids to settle naturally through static settling – this method also proves to be very effective.
Using the method of letting it settle naturally takes too long, and the solid matter that settles down is difficult to handle!
At present, adding additives by solidification remains the most effective method, with the greatest number of research findings available; this approach could be considered.
There is an oil slurry filter and an ash remover; I don’t know if the original poster is satisfied
Oils with a high solid content can be stored in separate tanks, where they can settle naturally by allowing them to stand still, and this method also yields good results.
Add a sedimentation agent; as far as I know, all filters used do not yield good results. The latest sedimentation agents can reduce the solid content to below 500 ppm, with a sedimentation time of within 48 or 24 hours
Our company has a product that uses a scraper-type high-viscosity medium filter; if you’re interested, feel free to get in touch with me. The filtration precision reaches 1 micron
Maybe centrifugation could be tried. Small size, high processing capacity.

The best method for treating catalytic slurry at present is adding agents for sedimentation; it yields good results, with a removal rate of over 90%, allowing for long-term operation. The initial performance of filtration is good, but the maintenance costs are high over time; its performance during long-term operation is poor, and its effect on sedimentation is very poor
