On flue gas desulfurization treatment in catalytic cracking
Thread Content
Let’s discuss what technologies are being used and how to deal with issues related to liquid and white substances
Regarding catalytic flue gas desulfurization in China, as far as I know, Sinopec used the Na-based desulfurization process developed by Berger, while CNPC employed the Na-based desulfurization process developed by Norton. In recent years, ammonia-based desulfurization and semi-dry desulfurization methods have been used; it seems there are also systems that employ Consol’s organic amine desulfurization technique. Each of these methods has its advantages and disadvantages. I’ve heard that there is also a sodium thiosulfate-based desulfurization process, but I’m not sure if it has been used in any practical applications. When there is liquid involved, the only situation I’m aware of is when the tower is undersized and the gas flow rate is too high; after all, I’m not a professional technician. It’s best to ask the manufacturer who built your tower about this issue, or consult peers with similar installations and ask them how they handled it:D
Thank you. Thank you very much. Recently been in communication
