Beschreibung
Zusammenfassung:	The invention relates to a method for treating aromatic mineral oils or mixtures of aromatic mineral oils and naphthenic mineral oils, said oils or mixtures of oils being loaded with polycyclic aromatic hydrocarbons. The method comprises the following steps: a-optionally removing polycyclic aromatic hydrocarbons having a molecular weight greater than or equal to 200 from aromatic mineral oils loaded with polycyclic aromatic hydrocarbons or a mixture of aromatic mineral oils and naphthenic mineral oils; b-extracting the polycyclic aromatic hydrocarbons having a molecular weight of less than 200 dissolved in the oil or the mixture of oils obtained in step (a) at a pressure of less than atmospheric pressure; and c-recovering the polycyclic aromatic hydrocarbon-depleted oil or oil mixture. 本发明涉及一种处理芳香族矿物油或芳香族矿物油与环烷族矿物油的混合物的方法，所述油或油的混合物加载有多环芳烃，其特征在于，所述方法包括以下步骤：a-从加载有多环芳烃的芳香族矿物油或芳香族矿物油与环烷族矿物油的混合物中任选地去除分子量大于或等于200的多环芳烃；b-在低于大气压的压力下，对步骤(a)中获得的溶解在油或油的混合物中的分子量低于200的多环芳烃进行提取；c-对多环芳烃贫化的油或油的混合物进行回收。
