Separation of solvent and deasphalted oil for solvent

Among many existing upgrading processes, solvent deasphalting (SDA), a technology for removing asphaltene-rich pitch and producing higher-value deasphalted oil (DAO) by using paraffinic solvents, is promising because it offers the advantages of low installation cost and flexibility in terms of the control of the quality of pitch and DAO.

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 contains the majority of the residue’s contaminants (metals,

Residue upgrading - DigitalRefining

Solvent deasphalting (SDA) has a key role in today’s refinery, as the technology can be used in a variety of ways for residue upgrading. It is less expensive to build and operate than other residue conversion processes and is especially useful in recovering large quantities of high-quality oils, which can be further upgraded via traditional
