The Role of Solvent De-Asphalting (SDA) in Refining

2020-12-15  Deasphalting as the solvent used was propane. • Today, the SDA process can use C3, C4, and C5 or some mixture to further optimize the DAO/Pitch separation. The lighter the solvent, the cleaner the DAO but the lower the recovery. • Additionally, the SDA process has been modified to

Deasphalting FSC 432: Petroleum Refining

Deasphalting. While distillation achieves separation/fractionation of the feed components with respect to differences in their boiling point, deasphalting (as a solvent extraction process) fractionates the feedstock, atmospheric, or more often vacuum distillation residue (VDR), with respect to solubility/insolubility of molecular components in a given solvent.

Deasphalted Oil - an overview ScienceDirect Topics

Solvent deasphalting (SDA) is a unique separation process in which the residue is separated by molecular weight (density) instead of by boiling point, producing a low contaminant deasphalted oil (DAO) that is rich in paraffins. It has the advantage of being a relatively low cost process that has flexibility to meet a wide range of DAO qualities.
