Fluid catalytic cracking features

With this decision made, Ashland set out to develop a new residual oil conversion process which could effectively produce a greater amount of transportation fuel from each barrel of crude processed. It was concluded that a new process would take the best features from the fluid catalytic cracking process and couple them with innovative improvements in related key areas such as unique... 

PetroFCC [Petrochemicals Fluid Catalytic Cracking] A modified FCC process that increases the yields of propylene and butene for use in petrochemical manufacture. The modifications are mainly to the engineering and involve a dual reaction zone with a single regenerator. One feature is RxCat technology, which involves mixing some of the spent catalyst with regenerated catalyst in a separate chamber. Developed by UOP in 2000 and licensed for use in the Philippines in 2008. 

Application When the process objective is maximum propylene production, specific technology features must be added to the fluid catalytic cracking (FCC)/resid FCC (RFCC) unit. The challenge is particularly great when the feedstock contains residue. 

Figure 4.1 Schematic of principal features of a modem fluid catalytic cracking (FCC) reactor system.

The DuPont process incorporates design features of fluid catalytic cracking (Chapter 14) in addition to many features that are unique to chemical synthesis reactors.
