A. SOLVENT EXTRACTION AND DEWAXING

A. SOLVENT EXTRACTION AND DEWAXING . 1.Description . Solvent treating is a widely used method of refining lubricating oils as well as a host of other refinery stocks. Since distillation (fractionation) separates petroleum products into groups only by their boiling-point ranges, impurities may remain.

A Review on Solvent Extraction of Nickel - ijert.org

Solvent extraction (SX) is one of the most important separation processes in hydrometallurgy. Solvent or liquid-liquid extraction is based on the principle that solute can distribute itself in a certain ratio between two immiscible solvents [16]. Solvent extraction becomes a popular separation ...

commonly used reactions in solvent extraction of inorganic as well as organic compounds. (Note: the term adduct is often used both for the donor molecule and for its product with the solute.) The next process is the extraction of the complex (Step 4). Even if the solubility of the adduct former TBP in the aqueous phase is quite small (i.e., D
