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

Potential Opportunities for Similar Scheme


17

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
