Title

Comparison of Extractive and in Situ FT-IR Measurements During Incineration of Chlorinated Hydrocarbons

Abstract

Many technologies are emerging for improved incineration of hazardous wastes. The environmental impact of thermal destruction systems can be compounded by the fact that thermal treatment of halogenated wastes may result in the production of secondary wastes more toxic than the primary waste. The production of air toxics was investigated during the pyrolysis and combustion of benzene and o-dichlorobenzene (o-DCB) with in situ and extractive Fourier transform infrared (FT-IR) spectroscopy as well as off-line gas chromatography/mass spectrometry (GC/MS). The combination of FT-IR and GC/MS analyses was able to elucidate the effects of temperature and Cl concentration on the formation of polynuclear aromatic hydrocarbons (PAHs). We were also able to identify potential indicators of air toxic formation which can be used for on-line process control of hazardous waste incineration.
