127740 - LCA Modelling of Forged Components for Turbomachinery: Improved Approach Based on Production Data 

In the current global scenario, where industries, countries, and international cooperation policy makers are increasing their efforts to fight Climate Change, also turbomachinery sector is needed to contribute. Most turbomachinery components are produced with forging processes due to high material properties requirements. However, there is still a need to develop a more detailed methodology to perform a Life Cycle Assessment on these components, since available commercial software does not always guarantee a customized inventory based on specific material or processes used in turbomachinery industry and their production data may require huge extrapolation, increasing the uncertainty related to their outputs. Additionally, the forging process is strictly dependent on geometry, material, and size of component produced. The aim of this work is to propose a robust and automated calculation process of the environmental impact of a semi-finished forged component considering all the processes required for its production. A tool has been developed, taking energy and material flows as inputs, and based on validated databases and Baker Hughes supply chain real data. In this way a new methodology for a fast estimation of environmental impact is obtained, which considers machine parameters of the processes, estimating the energy consumption. Gas turbine components are used as case study, and pedigree matrix comparison between the two methodologies is reported.
