Process for the incineration of chlorinated organic materials

Abstract From the Canadian patent

Molecular chlorine level in flue gases from incineration of chlorinated organic materials is reduced by injecting into the incinerator's quench zone an amount of a C1-C4 hydrocarbon which depends on the amount of air fed into the combustion zone, the amount of air being such that there is a 1-40% excess of oxygen. When the wall temperature of the combustion zone is about 800-1500°C the temperature at which the hydrocarbon is added to the quench zone is about 450-1000°C. Hydrogen chloride which, is formed from molecular chlorine and hydrocarbon is more, readily water-scrubbed than chlorine so that less pollut-, ing flue gases are obtained.
