WebN2 - The solvent deasphalting (SDA) process is a heavy oil upgrading process and used to separate asphaltene, the heaviest and most polar fraction of vacuum residue (VR) of heavy oil, by using density differences, to obtain deasphalted oil (DAO). The SDA process consists of two main stages: asphaltene separation and solvent recovery. WebAug 13, 2024 · Historically, solvent deasphalting of vacuum residues has been used in the manufacture of lubricating oil to separate out the heavy fraction of crude oil beyond the range of economical commercial distillation, using propane as solvent. The feed to the deasphalting unit is usually a vacuum resid with a 950°F TBP cut point. Over time, this …

The metals concentrate in the solvent-insoluble phase and the deasphalted oil is decreased in metals content. A limitation of art-processes is that as the yield of deasphalted oil increases, so does the metals content. grange hill mr humphries
