Abstract
System and method for reducing mutagen levels contained within a volume of petroleum aromatic extracts. The petroleum aromatic extracts are mixed with at least one solvent. This produces a mixture. Once mixed, some of the petroleum aromatic extracts dissolve. Others settle in the mixture. The petroleum aromatic extracts that have settled on the mixture are removed from the mixture and are ready for use. The mixture is heated to evaporate the solvent from the mixture. The evaporated solvent can be recaptured and reused. The residuum of the mixture contains petroleum aromatic extracts that can be partially recovered using traditional hydroprocessing techniques.
