Submerged plasma slag fuming technology is a process intensification of the traditional (coal-fired) slag fuming technology. A general dynamic model of the plasma-driven slag fuming process has been developed in FactSage 7.0 based on Metallo Belgium’s industrial-scale submerged plasma slag fuming furnace. This model describes the chemical reactions, phase equilibria and heat transfer in each sub-unit operation, and the heat and mass transfer between the subsequent sub-unit operations of the slag fuming process. The model was validated on several process batches. Upon assessing the simulation results, a deviation was found from the industrial process, which can be explained using kinetic factors.
