Reduction of organochlorine emissions from municipal and hazardous waste incinerators

Formation of chlorinated aromatic hydrocarbons by thermal decomposition of vinylidene chloride polymer

“…Since this pyrolysis was performed without flame, it is not strange that the profile of pyrolysis products in this experiment was different from that of incinerators. Dougherty and Collazo-Lopez (25) reported formation of polychlorinated pyrenes or fluoranthenes by thermal destruction of poly(vinylidene chloride) at 1000 °C. None of them was detected in this experiment.…”

“…Ballistreri et al observed the formation of dichloroethylene, trichlorobenzene, and tetrachloronaphthalene by pyrolysis of poly(vinylidene chloride) in an ion source of mass spectrometer (24). Dougherty and Collazo-Lopez (25) showed that compounds tentatively identified on pyrolysis products of poly(vinylidene chloride) at 1000 °C were hexachlorobenzene, pentachlorophenol, chlorinated styrenes, chlorinated naphthalanes, PCBs, chlorinated polynuclear aromatic compounds, etc. Recently, Yamaguchi et al (26) presented the emission of a fairly large amount of polychlorinated benzenes and PCBs from the reclaimed land in Japan and also suggested that the compounds might come from thermal decomposition of polymers containing chlorine substituents.…”

Thermal Treatment of 1,2,3,4-Tetrachlorodibenzo-p-dioxin by Reaction with Ca-Based Sorbents at 23−300 °C

“…A possible answer to the fate of chloroaromatics in CaO systems may have been reached by Dougherty and Collazo-Lopez (9) when they tested the gaseous emissions from the thermal destruction of polyvinylidene chloride in a 1000 °C tube furnace. The emissions were passed through a fluidized CaO bed resulting in a 300-fold decrease in aromatic polychloride effluents.…”
