In this study, advanced exergy analysis of the nitrogen liquefaction unit was performed using the cryogenic liquefaction method. Advanced exergy analysis consists of four different splitting. These; endogenous/exogenous and avoidable/unavoidable exergy destruction. In the study, forward exergy analysis was performed for each component and endogenous, exogenous, unavoidable and avoidable values of these components were calculated. In the result of the study, the highest endogenous exergy degradation was found in the CM1 compressor with 32.56 kW, the highest exogenous exergy destruction was in the HE3 heat exchanger with 25.8 kW, the highest unavoidable exergy destruction was in the CM1 compressor with 22.55 kW and the highest avoidable value was in the HE1 heat exchanger with a value of 17.76 kW. Total exergy destruction of system were calculated as 755.08 kW.eninfo:eu-repo/semantics/closedAccessAdvanced Exergy AnalysisCryogenic SystemExergy AnalysisLiquefaction UnitConference Object50N/A39
