The Role of Solvent DE Asphalting SDA in Refining

A Solvent Deasphalting (SDA) unit provides a different approach to molecular management. Solvent deasphalting or SDA is a separation process based on differences in molecular types rather than boiling point differences. SDA is a liquid- liquid extraction process where very heavy molecular weight asphaltenes are separated out of heavy oils.
