Catalyst fluidization at the beginning of operation
Thread Content
How can one determine whether the catalyst is flowing properly between the two reactors at the beginning of operation when no crude oil is fed in?
Looking at the inlet and outlet pressure difference, the pressure difference after fluidization is relatively lower.
Once the fluidization is normal, check the amount of material stored in the regenerator; there should be no leakage of material, and the temperature of the lift pipe should also be normal – this indicates that everything is working properly!
