“…The reactions that can occur between the identified species and free radicals were taken from propane combustion models (GRI-Mech 3 [12]) and from publications concerning TCE combustion in a flame [6,7,13,14], for a total of 330 reactions. The Cl to Cl 2 recombination reaction, Cl ?…”

This work deals with incineration of organic liquid wastes using an oxygen thermal plasma jet, submerged in water. The results presented here concern incineration of trichloroethylene (TCE). During a trial run, the CO 2 and CO content in the exhaust gas is continuously measured; samples taken periodically from the solution are analyzed by appropriate methods: total organic carbon and chlorine content are measured. Process efficiency during tests with a few L/h of TCE is given by the mineralization rate. The trapping rate of chlorine as HCl is near 100 %. The TCE destruction and removal efficiency, measured by MS/GC, is better than 99.9999 %. A simplified kinetic model of gas quenching was constructed from a single-phase plug-flow reactor model taking into account 14 species and 34 reactions. It satisfies the requirements of heat balance and major components analysis, and reveals the major role of the OH radical on the concentrations of CO as well as HCl and/or Cl 2 in the off-gas stream.

“…The chlorinated compound thus can be exposed to temperatures in the normal operating range for incinerators (1100 to 1500 K for liquid injection incinerators, and 900 to 1600 K for rotary-kiln incinerators (Oppelt, 1987))or to lower temperatures to simulate incinerator failure modes. A complete description of the experimental facility and methods is published in Fisher (1990). Figure I shows the apparatus and sampling system as used for these studies.…”

“…Compensation of this effect may well occur because the co-injected N, cools the same region by dilution, thus reducing the maximum temperature experienced by CHC. Gas sampling and measurement techniques are described in detail elsewhere and are summarized here (Hall et al 1991;Fisher, 1990). Gas samples are collected through quartz probes and stainless-steel tubing (type 304; 4.8 mm 00).…”

“…Ethyl chloride (C 2H sCI) was chosen as the first compound for study because it was easy to handle and the Icast toxic of the chlorinated hydrocarbons. Findings of its thermal destruction characteristics, reported elsewhere (Fisher et al 1990) are summarized here and discussed in the context of this overall study of chlorinated C, and C 2 hydrocarbons. Methyl chloride (CH,CI) and I, I, I-trichloroethane (I, I, I-C 2H 3CIJ ) were studied also.…”

Although hazardous waste incinerators attain high destruction efficiencies during steady-state operation, off-design conditions may pose emissions problems. Our goal has been to stimulate certain incinerator failure modes and investigate their impact on destruction efficiency and evolution of byproducts from chlorinated wastes. The experimental simulation involves injecting a small quantity of the chlorinated hydrocarbon (CHC) of interest into the post-flame region of a turbulent combustor. The temperature and environment to which the compound is exposed are characteristic of incinerator failure conditions. The chlorinated C, and C, compounds studied include CH,CI, C,H,CI and I, I, I-C,H,CI" We observe the breakdown of each compound under varying temperature conditions. In the highest temperature cases destruction of the CHC is quick, and observed product species are HCl, CO, H 20 and CO,. As the injection temperature is decreased, both chlorinated and non-chlorinated byproducts are observed. The reactions are modeled, assuming plug flow and the measured temperature profile, using CHEMKIN with the SENKIN driver program. Our chemical kinetic mechanism distinguishes between the isomers of all the C 2 chlorinated species. We examine and compare the influence of temperature, chlorine loading and molecular structure on destruction efficiency and by product distributions for the C, and C, compounds.
