Title

Using Hydrogen Peroxide Or Ozone To Enhance The Incineration Of Volatile Organic Vapors

Abstract

The destruction of certain hazardous Volatile Organic Compounds (VOCs) by incineration requires high temperatures and long residence times. This oxidation process occurs by a complex series of chemical reactions, initiated and propagated by the reactive radicals: hydroxyl (OH), oxygen atoms (O), hydrogen atoms (H), and hydroperoxyl (HO2). It was postulated that the addition of radical sources-such as hydrogen peroxide (H2O2) or ozone (O3)-to a heated stream of VOCs in air, would enhance the kinetics of the thermal oxidation. In practice, addition of enhancers to post-flame gases in a real incinerator should result in lower incineration temperatures or shorter residence times to obtain the required destruction and removal efficiency (DRE). In this work, the VOCs studied include n-heptane, chlorobenzene, and isopropanol; less extensive experiments were also conducted on trichloroethylene and heptane/chlorobenzene mixtures. The reactor was a 200 cm long, 6 mm diameter quartz tube, externally heated in a Lindberg tube furnace. The experiments were run isothermally for temperatures from 637°C to 750°C with residence times varying from 0.25 to 1.0 seconds at four or five different concentrations of H2O2 or O3. The results of these experiments show that the introduction of H2O2 clearly enhances the destruction of the VOCs tested. Ozone was these to be less versatile than hydrogen peroxide because it was effective in the incineration of the alkane but not on the other compounds. © 1993.
