US 2026/0109815 A1 · LIQUID PHASE EXTRACTION OF TRITIATED AND RADIATION-GENERATED IMPURITIES FROM ORGANIC AND ORGANOSILICON OILS

Abstract

A method for removing impurities from a damaged oil including an oil and impurities is provided. The method includes mixing the damaged oil with a solvent to form a mixture containing a solvent phase and a non-solvent phase and separating the solvent phase from the non-solvent phase. The solvent phase contains the solvent, recovered oil, and impurities in a first concentration. The non-solvent phase contains impurities in a second concentration. The second concentration is higher than the first concentration.
