June 12, 2008 - "Axens’ PetroRiser Converts Residue to Propylene"
Axens announces the commercialization of its new Resid Fluid Catalytic Cracking (RFCC) PetroRiserSM technology for the production of high yields of propylene. This new resid-to-propylene technology is part of the FCC Alliance between Axens, Shaw, Total and IFP.
The PetroRiser technology incorporates a second riser into the RFCC complex. The light cracked naphtha produced in the first riser is sent to an independent cracking riser, enabling each riser to be operated independently, thereby providing optimal conditions to enable both high propylene production and reduce delta coke make. PetroRiser produces 12 wt% propylene compared to a classical RFCC, which produces about 5 wt%. In addition, the economical benefit increases an additional $1.2 per barrel of residue. Additional technology can further improve propylene yield gains by 2-3 wt%.
With gasoline-to-propylene price differentials expected to remain strong, PetroRiser has some unique economic advantages.
