One common method is solvent extraction, where the neutral oil is washed with solvents like furfural or phenol. Bleaching: Passes the oil through bleaching clays to adsorb any remaining color compounds and trace metals.
How Food Grade Mineral Oil Is Made: Key Purification and Additive Processes
However, in industrial lubricants, you might find additives like antioxidants to prevent degradation, pour point depressants to improve low-temperature flow, or anti-wear agents to enhance lubrication. " Key Purification Processes Solvent Extraction: Uses selective solvents to remove unwanted aromatic compounds and impurities.
These solvents selectively dissolve the unwanted aromatic compounds and other impurities, leaving behind a more saturated hydrocarbon chain. This unrefined mixture contains a vast array of hydrocarbons, ranging from light gases to heavy, viscous compounds.
