Market trends – Global chemicals growth

Integrated “Crude to Chemicals”

complexes

• Maximize chemical derivatives

• Minimize heavy fuels (diesel, fuel oil)

• Proven / demonstrated technology (lower risk)

Drivers

• Growing domestic chemical demand

• Government drive to strengthen domestic

petrochemical industry, back out imports

• Opening up of crude import licenses

• Value chain integration

• Reduce exposure to regulated fuel product

prices / taxes

• Rise of independent companies vs. NOC

Announced crude to chemicals complexes

• New resid technology is required and is being built with

naphtha steam cracker and aromatics

• Additional product and energy integration into a new

petrochemical complex

• FLEXICOKING™ light naphtha: to steam cracker after

treatment

• FLEXICOKING™ heavy naphtha: to reformer after

treatment

• FLEXIGAS and FLEXICOKING™ fuel gas:

• to co-gen provide 100% of power/steam

requirements for aromatic complex & steam

cracker during normal operation
