ABSTRACT:
Prior to passing through pumping apparatus effluent gas containing hydrocarbons is subjected to washing by being sprayed with aromatic type oil in oil-recirculating washing apparatus. Polycyclic aromatic hydrocarbons contained in the effluent gas are trapped by being absorbed in the oil. The method is suitable for treating effluent gas coming from an installation for chemical vapor deposition or infiltration using a reagent gas containing a precursor for pyrolytic carbon, or else coming from a cementation installation.
