FCC Technology Features
 Stripper packing
 Prevents the loss of valuable products
 Allows operation at higher ROT for same
regenerator/MAB capacity
 > 60 references, >30 operating
 Feed injectors
 Ensure proper feed distribution to
maximize catalytic reactions while
minimizing thermal reactions
 > 100 references

FCC Technology Features
 Catalyst cooler and MTC (Mix
Temperature Control)
 Allows operation at higher severity/coke
make at full conversion vs. unit mechanical
design
 > 65 references for Catalyst Cooler
 RS² Riser Termination Device and
Vapor Quench
 Ensure limited thermal degradation of
products through reduction of residence
time and HC outlet temperature
 > 25 references for RS², 13 operating

Closing the Heat Balance: Tailor-made Solutions
 Turbulent Regenerator with
Swage and Air Rings
 HCO/Slurry recycle to Stripper or
Riser
 Air Heater & Torch Oil injection
able to operate continuously
 Added benefit: more valuable
energy recovered from flue gas
thanks to a lower acid dew point

 Improved heat balance
MTC usage
 Improved global conversion
ZSM-5 injection
 Enhanced propylene
production through
conversion of
intermediate olefins
Feed processing at Maxi
Distillate optimal conditions
Co-processing of Coker HGO
 Improved margins
Light slurry recycle upstream feed
injection

Potential Opportunities for Similar Scheme
 Coker HGO co-processing (10-15%)
• No penalty on C3= production through severity increase
• Yields interesting quantities of LCO
• No impact on LCN quality
• Helps improving the heat balance
• Marginal impact on downstream hydrotreatment
• Additional revenue could be as high as 16 MMUSD/year
› Compared with conventional VGO
› Price spread considered: 200 USD/ton
 Heavy Aromatics purge / Slurry Oil recycle
• Disposal of low value cuts / Nil fuel oil production
• Direct contributor to the heat balance (coke production)
• Yields minor amounts of valuable products

Conclusions
 More than ever, the FCC unit can hold a predominant
place in the refining scheme, whichever are the
production objectives
 Deeper integrations between refinery and
petrochemical complex pave the way for further
enhancements of the FCC technology oriented
towards petrochemical bases production
 Opportunities must be seized to improve FCC
operation and margins
