2020-9-1  Abstract. Solvent deasphalting of vacuum residue using carbon dioxide-toluene mixture was studied to assess the effect of the process parameters and mixture composition on the yield and composition of deasphalted oil (DAO) produced. An insignificant effect of the toluene content in the mixture on the DAO yield was found at a concentration above ...

Solvent Deasphalting - Chevron Lummus

The CLG Residue Solvent Refining Solvent Deasphalting (RSR) process is a specialized solvent extraction process that separates by molecular type instead of by boiling point, as in the vacuum distillation process. RSR recovers a low-contaminant, relatively high in hydrogen content, deasphalted oil product (DAO) from the residue.

Solvent Deasphalting (SDA) Lummus Technology

Solvent deasphalting (SDA) is a separation process in which residues are selectively separated by molecular type by mixing with paraffinic solvents and precipitating out of solution asphaltenes and other residue heavy components. SDA produces a low-contaminant, relatively high hydrogen deasphalted oil product (DAO) and a pitch product that ...

1997-10-12  Solvent deasphalting is a proven process for extracting a high purity deasphalted oil (DAO) from atmospheric or vacuum residues. The residual asphalt concentrates asphaltenes, metals and other contaminants. As a general trend, when the DAO yield increases, its purity decreases while asphalt becomes harder and more difficult to handle.
