Abstract: In a method for reconditioning an industrial oil and in an oil recovery system therefor, a used industrial oil is reconditioned by adding a liquid separation booster to the used industrial oil, and then the separation booster with attracted impurities is separated from the used industrial oil while leaving at least one specific additive in the oil. The separation booster is designed to attract impurities in the used oil while not attracting at least one specific additive in the oil.

Abstract: A liquid composition for use in purifying an oil contains a polar polymer, a surface active hydrotrope/solubilizer, and a co-tenside. The polar polymer may be a polyalkylene glycol, such as polyethylene glycol. The hydrotrope/solubilizer may be an anionic sulfonic acid, a phosphate ester-based substance or a non-ionic surfactant from the poly-glycoside family. The co-tenside may be at least one amphoteric co-surfactant, such as sodium caprylimino dipropionate.
