H-Oil® & Other Technologies Combination

Market Trend:

Maximize Conversion

Maximize Middle Distillates production for higher profitability

Combination of H-Oil® & existing coker unit

OIL REFINING

PETROCHEMICALS

Maximize Heavy Naphtha production for Petrochemical application

Combination of H-Oil® & Solvahl™ (SDA) Take advantage of existing assets for Carbon rejection

With increased conversion, the stability is the limiting factor due to Asphaltenes condensation

One option is to use SDA to eliminate remaining Asphaltenes
