Purification technology for catalytic slurry
Thread Content
With the increasing heaviness of crude oil and the diversification of catalytic processing techniques, higher demands have arisen for the development of catalytic cracking processes. Currently, catalyst particles can cause problems such as nozzle wear and blockage; meanwhile, fine catalyst particles in the flue gas accumulate on the surface of the heating furnace tubes, resulting in reduced thermal efficiency and increased energy consumption, which in turn makes it difficult to purify the catalytic slurry. There is a need to find a mature purification technology for catalytic slurry – a technology that can remove solid catalyst particles and other impurities from the slurry produced by catalytic cracking units. If you have a solution, please feel free to contact me
1. There is a sedimentation agent that can remove at least 90% of particulates. 2. Filter, resulting in 20PPM after filtration.
By the way, are there many units that still recycle oil slurry?
Could you please provide more specific details? It would be better if you could name a manufacturer. Thank you
1. Slurry clarifiers are available from Nalco and Baker Hughes. 2. For slurry filters, I recommend MOTT’s.
We haven’t carried out reprocessing for a long time; apart from increasing coking in the reaction, reprocessing the slurry doesn’t result in any significant changes in yield
Thank you. Contact them for consultation when you need it
This problem has been solved for over 2 years now, with very good results. You can go to Lihua Yi to take a look – catalytic slurry is filtered before being sent for hydrogenation, and the product used there is from Dalian Zhongkai Chemical.
It seems that the catalyst powder in the slurry is quite difficult to handle
