Solvent Deasphalting (SDA) - poerner.at

Solvent Deasphalting is one of the most interesting "Bottom-to-Barrel" technologies to process heavy residues in modern refineries. On the one hand due to the major price differences more and more heavy, high-sulfur crudes are used in refinery processes rather than light, low-sulfur crudes and on the other hand it requires more efficient residue processing technologies.

Refining Community » Solvent Deasphalting 101

Solvent Deasphalting (SDA) is a highly efficient crude oil pretreatment– a separation process within the oil refining process typically utilized in a crude oil process or bitumen upgrader. It separates the crude according to molecular type, dissolving certain components and then leaving behind a residue which contains contaminants.
