Processes PetroFCC

The PetroFCC process changes an FCC unit from a gasoline-producing device to a source of petrochemical feedstocks. It can provide both aromatic naphtha to an aromatics complex and light olefins to a polyolefins complex. Feedstock utilization can be further improved by recycling the raffinate by-product from BTX solvent extraction back to the PetroFCC reactor for conversion to light olefins. 

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. 

The PetroFCC process employs several measures to improve the yield and selectivity of propylene and lower the 5deld of dry gas ... 

HOCC [High-Olefin Catalytic Cracking] A general name for such processes, including CPP, DCC, and PetroFCC.
