Good discussion. How Can I predict when I need to stop the FCCU turbo expander related with catalyst loss from regenerator ? During the FCCU regular campaign there is a loss catalyst from the regenerator to turbo expander and it increase. What do I need to measure in order to shutdown the turbo expander if the loss catalyst reach a determined point ? We need to know this point to protect the turbo expander from FCCU loss catalist.
