On-line diagnostic of the gaseous effluent of a fly ash treatment plasma process: Set-up of a chemical balance

Abstract : Plasma processes are today considered as one of the most promising techniques for the treatment of industrial or domestic waste incineration for they are fast and cheap in terms of energy consumption. The most important part of this paper relies on the development of a clean-up and GC/MS analysis protocol for fly ash volatile organic compounds identification, and on the monitoring of metallic oxides and chlorides evaporation during the plasma treatment by optical emission spectroscopy. Thermal and chemical balances were evaluated in order to optimize the process, also in regards to environmental regulation constraints.
