Jp. Aittola et al., FORMATION OF CHLOROAROMATICS AT A METAL RECLAMATION PLANT AND EFFICIENCY OF STACK FILTER IN THEIR REMOVAL FROM EMISSION, Chemosphere, 32(1), 1996, pp. 99-108
Sampling and analyses of chloroaromatic compounds emitted from the met
al reclamation plant of Kuusakoski Ltd in Heinola, South Finland, were
continued in order to find out formation pathways and to follow the i
mpact of process improvements done in 1991-92. Especially, process gas
cleaning by baghouse filter at aluminum smelter plant (ALS) and by sc
rubber at car schredding (CSH) were successful in emission control. At
ALS, reductions of polychlorinated dioxins, furans, planar PCB's and
dibenzothiophenes were better that 90, naphthalenes 78, other PCB's 73
, chlorobenzenes 51 and chlorophenols 43 per cent. CSH scrubber gave s
imilar results.
