3.5 million tons of catalyst? There aren’t many sets left in the whole country at the moment.
Diagrams with PID values may not be available even if requested from design institutes. These drawings must cost money, right? After all, they are typically technical documents provided by design firms to clients or general contractors, and they are considered confidential files.
This must be kept confidential; generally, a third-party confidentiality agreement is required, and even if it is deciphered, you won’t be able to see it without the decryption key. :lol
I’ve really never seen such a large catalyst before; there aren’t many of them, I hope we can exchange more ideas.
It’s not that complicated; many people have it, they just don’t dare to contribute.
For catalysts of this grade in the surrounding area, they are generally of the JGC type, designed by GS Company, and feature two-stage turbulent bed coaxial regeneration using Shi Wei technology. In China, it may have been developed independently by drawing on UOP’s turbulent bed regeneration technology for pre-coking tanks, or it may have adopted UOP’s process package design, as in the cases of Guangxi Petrochemical, Yunnan Petrochemical, Sichuan Petrochemical, etc. Catalysis technology has now matured, and there is little further progress in research. The experts who specialize in catalytic cracking have aged, and there are no successors.
It’s mainly due to process requirements; anything above 120 can generally be used as a reference
