Axens PetroRiser converts residue to propylene

Axens announces the commercialization of its new Resid Fluid Catalytic Cracking (RFCC) PetroRiser 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 reduced 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 USD1.2 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.
