Abstract: In this paper, an advanced exergoenvironmental analysis is conducted for a steam methane reforming process for the production of hydrogen. The approach for calculating pollutant formation is generalized and the assumptions required for applying the analysis are discussed in detail. These are the main contributions of this work to the development of exergy-based methods for the analysis of energy-intensive chemical processes. In an advanced exergoenvironmental analysis, the environmental impact associated with the exergy destruction within a component as well as the component-related environmental impact and a component-related pollutant formation are split into unavoidable/avoidable and endogenous/exogenous parts. This splitting improves our understanding of the sources of thermodynamic inefficiencies and their effect to the formation of environmental impacts and pollutants, and facilitates a subsequent improvement of the overall process. Finally, some improvement options developed on the basis of the results of the advanced exergoenvironmental analysis are discussed.
