Resumo: | There are many processes capable of decontamination of polychlorinated biphenyls in several matrixes. The set of inputs, materials, operation conditions and efficiencies are wide. The base catalyzed dechlorination process shows application potential in great scale, mainly due mild chemical reaction conditions and low cost raw materials. The KPEG is a familiar process of base catalyzed dechlorination. This decontamination treatment was developed mainly on mineral insulating oil. Few information is found related to process residues, usually in reaction sludge means, limited to inform that its destination must fulfill specific territorial laws. In these work KPEG treatment process was performed on decontamination of mineral insulating oils containing between 200 and 330 ppm of polychlorinated biphenyls to evaluation of reaction residues and of the decontamination percentage. Chemical characterization of these residual material allows achievement of important information to explore procedures for recovery, regeneration and/or right disposal. The analysis performed on the residues showed the presence of reaction products containing unsaturation, absents on neat polyethylene glycol, possible organic complexes products with alkali metal as also the presence of chloride ions. In oil was verified the presence of less chlorinated biphenyls, probably formed by partial dechlorination of highly chlorinated biphenyls. |

The KPEG is a familiar process of base catalyzed dechlorination. This decontamination treatment was developed mainly on mineral insulating oil. Few information is found related to process residues, usually in reaction sludge means, limited to inform that its destination must fulfill specific territorial laws. In these work KPEG treatment process was performed on decontamination of mineral insulating oils containing between 200 and 330 ppm of polychlorinated biphenyls to evaluation of reaction residues and of the decontamination percentage. Chemical characterization of these residual material allows achievement of important information to explore procedures for recovery, regeneration and/or right disposal. The analysis performed on the residues showed the presence of reaction products containing unsaturation, absents on neat polyethylene glycol, possible organic complexes products with alkali metal as also the presence of chloride ions.
