Life Cycle Assessment Applied to Naphtha Catalytic Reforming

摘要

Facing the increase of environmental concerns in the oil and gas industry, engineers and scientists need information to assess sustainability of chemical processes. Among the different methods available, Life Cycle Assessment (LCA) is widely used. In this study, LCA is applied to a catalytic reforming process using the Eco-Indicator 99 as life cycle impact assessment method. The main identified environmental impacts are fossil fuels consumption, climate change and respiratory effects due to inorganics compounds. The influence of different process parameters (feed composition, reaction temperature) is determined with respect to environmental impacts. Two allocation methods are analysed (mass and exergetic allocation) and two different process versions are compared in order to determine the effect of some improvements on environmental impact.
