The analysis of material and energy balance can be done using concept of exergy, which is
a measure of available energy in the system [1]. Exergy losses indicate the place of
degradation in the process; thus, it implies improving of selected process.
The aluminothermic reduction process is an attractive method for immobilization of
hazardous waste, and for utilization of valuable elements from the waste [2]. The exergy
calculation relies on the material and energy balance calculation and standard chemical
exergy of the elements. For the purpose of material, energy, and exergy balance calculation
discrete non-commercial software was developed [3]. The waste materials used in these
calculations are Electric-arc furnace dust (EAFD, mostly Fe and Zn oxides) and the Mill
scale (mostly Fe oxides) [4].
Calculated exergy efficiency for aluminothermic processing of waste was 94.6%. All the
heat released by exothermic reactions was used for producing the iron, the slag and the
crude ...ZnO dust. Comparing to the conventional carbothermic reduction process in the DC
electric-arc furnace with the same materials (for which exergy efficiency was 56.5%) this
is much higher. The irreversible exergy losses of the aluminothermic process are 398.2
kWh/t of produced iron. The further processing of slag and dust is required, as well as in
the case of the carbothermic reduction process, so that the real value of exergy efficiency
of the process will be somewhat lower than the calculated.
