    What is it the typical turnaround for maintenance of FCCU (feed is gasoil, RCR <0,5) and for CO Boiler ? In our case the typical turnaround for CO Boiler is 40 months (required by law). For FCCU is 5 years (required by law < 6 anos). In this case the FCCU continue in operation and CO Boiler is stopped. The emission (CO mainly) increase a lot and we do not use any additive in the process. What is the recommendation in this situation (FCCU in operation and CO boiler shutdown) in terms of emission ? Stopped both unit ? Anu additive ?
