FIELD: petrochemical industry; methods and the installations for treatment of the exhaust gases containing hydrocarbons.
SUBSTANCE: the invention is pertaining to the field of treatment of the exhaust gases containing polycyclic aromatic hydrocarbons, namely, to the treatment of the exhaust gases produced by the industrial installations for the chemical deposition or infiltration of the vapors for the purpose of formation on the substrates of the deposit of the pyrolytic carbon or compaction of the porous substrates by means of the mould made out of the pyrolytic carbon. The exhaust gases containing the hydrocarbons, before passing into the pumping out device (60) are exposed to cleansing by the method of sputtering of the oil of the aromatic type in the cleansing device (30) with the recirculation of the oil. The polycyclic aromatic hydrocarbons contained in the exhaust gases are trapped due to the absorption in the oil. The invention allows to ensure the good level of absorption of the resins of the exhaust gases, to eliminate the clogging of the channels, pollution of the environment by these resins and to limit the losses of the head.
EFFECT: the invention ensures the good level of absorption of the resins of the exhaust gases, elimination of the clogging of the channels, pollution of the environment by these resins and limitation of the losses of the head.
