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 ...

Solvent Deasphalting (SDA) - poerner.at

Solvent Deasphalting is one of the most interesting "Bottom-to-Barrel" technologies to process heavy residues in modern refineries. On the one hand due to the major price differences more and more heavy, high-sulfur crudes are used in refinery processes rather than light, low-sulfur crudes and on the other hand it requires more efficient residue processing technologies.

Refining Community » Solvent Deasphalting 101

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.

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.

Further to lighter solvents C 3-C 5 proving their performance in deasphalting, the current literature trends of SDA technology also indicate that the blend of n-alkanes and heavier paraffins like C 5-C 12 (including various types of naphtha, gasoline, treated/untreated naphtha etc.) can also perform SDA more economically as these streams are readily available in refinery at low cost , , , .

SOLVENT DEASPHALTING OF VACUUM RESIDUE IN A

The solvent deasphalting process (SDA) which is based on liquid–liquid extraction by using paraffinic solvents (C 4–C 7) is one of the most efficient approaches to reduce metal and asphaltene contents of heavy oil cuts before sending them to hydro-desulfurization and hydrocracking units.

Effect of temperature on the solubility of SARA

Solvent deasphalting (SDA) is a classical separating process in petroleum refining industry. However, the detailed mechanism is still unclear due to the complex chemical constitution of vacuum residue (VR). In the present work, molecular dynamics (MD) method was utilized to describe the experimental phenomenon at the microcosmic level.
