| 摘要 |
The present invention relates to a method for treating waste gas containing polycyclic aromatic hydrocarbons, comprising a stage of washing by spraying mineral oil in order to trap said hydrocarbons, characterized in that the mineral oil comprises a mixture of aromatic mineral oil and naphthenic mineral oil. The method further comprises the use of a naphthenic mineral oil to reduce the viscosity of an aromatic mineral oil loaded with polycyclic aromatic hydrocarbons, advantageously with an aromatic mineral oil containing at most 30% by volume polycyclic aromatic hydrocarbons. |
