Modeling of thermal treatment of solid wastes in electric arc melters for material recovery
31 Dec 1996
Abstract
Processing hazardous solid wastes in a DC arc melter offers several advantages over other competitive methods, including the ability to vary the mixture chemistry without impacting the energy input. This decoupling allows the melter to be operated in conditions which enhance material recovery. Predictive models can play a useful role in suggesting feed additives or operating conditions to achieve this goal. This paper describes the use of a model to investigate metal recovery through volatilization in batch melters. Chlorinated species are shown to be an effective additive; the potential to simultaneously treat solid wastes and chlorinated organics is also confirmed. At similar oxidation-reduction potentials the amount of chlorine, irrespective of molecular form, is found to determine the volatilization, with a linear relationship between chlorine feed amount and volatilization. In more reducing conditions, greater metal volatilization occurs.
