RESUMO

The concern with sustainable development has been taking to a constant improvement in the environmental management tools. Life cycle assessment (LCA) is a process, product or activity processes environmental impacts evaluation method using energy, material consumption and waste environmental releases. LCA is four steps constituted: goal definition and scope, inventory analysis, impact assessment and interpretation. In this work, Environmental Impact Assessment methodology was implemented based in LCA for the Hydrogen via natural gas steam reforming production process. A group of environmental indicators was calculated and allocated to the material balance. The secondary (steam generation) and fugitive emissions environmental impacts were also considered. The fugitive and secondary emissions have lower impact when compared to the reformer furnace exhaustion gases emissions of Inert Gases, Carbon dioxide, Water, Oxygen and NOx. The process environmental impacts are Human Toxicity, Acidification and smog effect due to NOx. There is also global warning due to Carbon dioxide emission
