H-Oil® & Solvent DeAsphalting Process (SDA) Combination
Market Trend:
Maximize Conversion
Maximize Middle Distillates production
for higher profitability
Combination of H-Oil® & Solvahl™ (SDA)
Option is to use SDA to eliminate Asphaltenes
OIL REFINING
PETROCHEMICALS
Maximize Heavy Naphtha production for
Petrochemical application
Stability is the limiting factor due to
Asphaltenes condensation
