What is solvent extraction process?

The solvent extraction process consists of five closely related subprocesses: solvent extraction, meal desolventisation, drying and cooling of the meal, distillation of the miscella and solvent recovery. Extraction is always used when a residual oil content of <2% is desired. Most vegetable oils are obtained by solvent extraction.

Can solvent extraction be used as a re-Rening technology?

This review focuses mainly on solvent extraction used as a re-rening technology, with adsorption as a nishing step. Although solvent extraction gives a well-rened oil, this setup is only useful on a commercial scale. Extracted oil also needs the re-addition of chemical additives to be reused in compatible systems.

Does oil decompose in a solvent extractor?

Oily materials with more than 30% oil by weight tend to decompose in the extractor after most of the oil has been extracted, resulting in poor final extraction and high solvent retention. Solvent extraction is most effective when the oily material contains about 20% of oil.

Are gas-based solvent-assisted mechanical extraction a good choice for industrial applications?

Since extraction remains the most critical step because of its impact on oil quality and quantity, new methods of gas- and solvent-assisted mechanical extraction have been proposed. The wide availability and low cost of petroleum-based solvents made them the best candidate for any industrial application.
