Solvent deasphalting – Petroleum Refinery,Petroleum ...

Solvent deasphalting is a pretreatment process for inferior residual oil. A petroleum product refining process for removing petroleum oil and bitumen oil from the vacuum residue obtained by distillation of crude oil (sometimes also from atmospheric residue) to obtain deasphalted oil and simultaneously producing petroleum pitch.. Raw materials: heavy oil such as vacuum residue

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.

Solvent Deasphalting 101 - Refining Community

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.
