| 摘要 |
<p>The invention concerns a method and an installation which consists in scrubbing a flue gas containing hydrocarbons by spraying aromatic oil in a scrubbing device (30) while recycling the oil before it passes through a pumping device (60). The polycyclic aromatic hydrocarbons contained in the flue gas are trapped by absorption in the oil. The method is suitable for treating flue gas derived from a chemical vapour infiltration or deposition installation using a reactive gas containing a pyrolytic carbon precursor, or a carburizing installation.</p> |
