Description

The Solvahl™ SDA Process produces a high yield of Deasphalted Oil (DAO) containing a minimum quantity of C5 and C7 Insolubles (commonly called Asphaltenes).

Solvents used in the Solvahl™ process can vary from C3 to C6 depending on Feed properties and Downstream Prrocess objectives.

The relative yields of DAO and Asphalt, as well as the characteristics of both Products, are linked to the nature of the Feed, the operating conditions and the Solvent Type.

The Process extracts a maximum amount of High Purity DAO at a low Solvent/Feed ratio, while producing Asphalt with a high softening point.

In general, the specifications for Asphaltenes and Conradson Carbon Residue for Hydrocracking and Fluid Catalytic Cracking are as follows:
• Hydrocracking (HyK): Asphaltenes < 0.02 wt %
• FCC: Conradson Carbon < 2.5 wt %
• Residue FCC: Conradson Carbon < 8.0 wt %.
