Abstract

Life cycle assessment is a useful tool to analyze the energy consummation and environmental emissions of the entire life cycle of a product. This paper analyzed the environmental impacts of a compressor rotor in its entire life cycle with an improved tiered hybrid analysis model which combines the process analysis and input-output analysis. Furthermore, the double-counting part was subtracted from the hybrid analysis model through the system incompleteness factor. The results show that primary energy demand (PED) and global warming potential (GWP) are two main environmental impact categories in the life cycle of the compressor rotor. And the usage stage contributes the most environmental impacts because of the large amount of electricity consumed. This study validates the effectiveness of the improved tiered hybrid analysis model. Adding the upstream production stage to the study system by input-output analysis can significantly decrease the truncation errors of process analysis.
