8. ■ Crude Oil selection
 Looking to crude origin may impact a lot on the CapEx
 Only API & sulfur content of the crude is not enough to select the correct
configuration and process units
■ Ensure flexibility of your assets over several decades years
■ Holistic approach to evaluate the choices of products, configurations and
technologies.
■ Envisage the future by different price set scenarios, long term contract on crude
and product

■ Breakdown of the economics taking into account 3 different blocks:
 Naphtha production (LN/HN)
 Aromatic complex: HN to
aromatics valorization
 Steam-Cracker: LN to olefins
valorization
■ Calculation is done as if the
three blocks were three
separated entities
■ Price set of the utmost
importance to evaluate the
complex:
 Delta price between olefins
and naphtha
 Delta price between aromatics
and olefins
