Switch FCCU from Partiall Burn to Fulll Burn

[SparshK]

Does anyone know if it is simple to switch a CO boiler at an FCCU from partial burn to full burn?

Dear Mr. Sparsh,
Switching of FCCU regenerator from Partial to full burn mode may call for change in MAB as the requirement of O2 increases or alternatively enriched oxygen may be used.
Increasing air flow increases superficial velocity in regenerator cyclones, which may call for change in cyclones or dia of regenerator also. All these parameters needs to be studied and analysed carefully before planning to shift from partial to full burn mode.

Medi.Ram-

Thank you for your answer. Do you have any literature or other insight that I can research to learn more about how these parameters can affect HCN production.

Best,
Sparsh
