Chlorinated aromatics from the combustion of hazardous waste
- 1985

Tidskriftsartikel (refereegranskat)abstract
- The production and emission of chlorinated aromatics from a hazardous waste incinerator were shown to be influenced by the operating conditions. The emissions of chlorinated benzenes, PCDD and PCDF show statistically significant correlations to the chlorine input. Different substance groups also correlate, and the results presented correspond well with a general formation mechanism of chlorophenols via chlorobenzenes as indicated by others.

- Here we present results from our tests with PCB-incineration at the SAKAB hazardous waste incinerator in Norrtorp, Sweden. Combustion tests were made with PCB both as a fluid (Arochlor 1242) and as a contaminant of solid waste (Arochlor 1016 in capacitors). A general conclusion was that the incineration of considerable amounts of PCB did not effect the production of PCDD and PCDF in this combustion plant.

Tidskriftsartikel (refereegranskat)abstract
- A large quantity of emission data for PCDD and PCDF have been reported to date. Less information is available concerning the controlling parameters for the production of chlorinated aromatics from waste combustion. Here we report results and conclusions from investigations carried out in the Scandinavian countries to date.

Emission and chlorination pattern of PCDD/PCDF predicted from indicator parameters

- The emission and chlorination pattern of polychlorinated dioxins and dibenzofurans from waste combustion shows a close covariation with that of chlorinated benzenes and phenols. This covariation can be utilized to predict the emission levels of specific isomers as well as the pattern of congeners.

- The production of polychlorinated dioxins and dibenzofurans shows a strong correlation with the production of hexachlorobenzene. Hexachlorobenzene can be used as an indicator for the production of chlorinated aromatics.

- Relations between different chlorinated aromatics have been evaluated in 66 samples from various industrial activities. For municipal waste combustion partial least squares modelling with latent variables (PLS) can explain 86 % of the variance in PCDD/PCDF from the isomerspecific analytical data for chlorinated benzenes and phenols.

Metal catalyzed formation of chlorinated aromatic compounds : a study of the correlation pattern in incinerator fly ash.

Tidskriftsartikel (refereegranskat)abstract
- Chlorinated aromatics are unintentionally formed and released from combustion and other thermal processes involving organic matter and chlorine. The catalytic activity of incinerator fly ash in the low-temperature formation of chlorinated aromatics has been demonstrated in both laboratory experiments and full-scale trials. Copper has been shown to be an effective catalyst, but several other transition metals possess a similar activity. Here results are reported from a series of full-scale combustion trials with different fractions of household and industrial wastes, with waste from forestry as a reference fuel. The composition of elements and chlorinated aromatics in the fly ash was evaluated with principal component analysis and partial least squares regression. The observed correlation pattern indicates that metals other than copper are of equal importance for the catalytic activity. Chromium and nickel are two of these metals, which may contribute to the de novo formation of chlorinated benzenes, phenols, PCDD and PCDF.
