Focuses on a thermodynamic analysis to determine whether it is suitable to predict the heavy metal (HM) speciation during the Municipal Solid Waste Incineration process. The fate of several selected metals (Cd, Pb, Zn, Cr, Hg, As, Cu, Co, Ni) during incineration was theoretically investigated. The equilibrium analysis predicted the metal partitioning during incineration and determined the impact of operating conditions (temperature and gas composition) on their speciation. The study of the gas composition influence was based on the effects of the contents of oxygen and chlorine on the HM partitioning. The results of the thermodynamic study were compared with those of characterization of real incinerator residues, using complementary techniques. These analyses were performed to determine experimentally the speciation of the three representative metals Cr, Pb, and Zn. |
