3. Life Cicle Inventory for Lead Azide Manufacture
ABSTRACT: Like any other manufactured chemical compounds, explosives are produced using chemical reactants and other utilities (steam, heat, compressed air, feed water and electricity) and generate a set of environmental impacts (waste water, solid and water residue and waste heat, for example). On top of that, one can count the intrinsic hazard characterist

5. DESENVOLVIMENTO DE METODOLOGIA PARA AVALIAÇÃO DA TENDÊNCIA À REOXIDAÇÃO DE PELOTAS DE MINÉRIO DE FERRO REDUZIDAS EM PROCESSO DE REDUÇÃO DIRETA A GÁS / DESENVOLVIMENTO DE METODOLOGIA PARA AVALIAÇÃO DA TENDÊNCIA À REOXIDAÇÃO DE PELOTAS DE MINÉRIO DE FERRO REDUZIDAS EM PROCESSO DE REDUÇÃO DIRETA A GÁS
Among the alternative processes for reducing iron oxide to produce iron and steel, the most currently used is the Midrex technology. The product may be the sponge iron, also called DRI (Direct Reduced Iron), composed mainly of metallic iron and iron oxide, or HBI which is the DRI pressed in the form of briquettes. DRI has a tendency to reoxidation in air, es
