Abstract: Conventional exergy analysis can be only used to make a quantitative analysis of the exergy destruction and exergy efficiency of equipment, and cannot reflect the improvement potential of the exergy destruction of the equipment. In order to analyze the energy consumption of the equipment in the condensate recovery process, an advanced exergy analysis is performed on the direct heat exchange process. Advanced exergy analysis is adopted to evaluate the exergy destruction forms of each component to reflect the interaction between components and identify the improvement potential of exergy destruction. The results show that avoidable endogenous exergy destruction of most equipment accounts for the highest proportion of the total exergy destruction, indicating that process improvements should focus on device performance rather than process structure. The most effective measure to reduce process exergy destruction is to improve compressor efficiency, followed by transforming the heat exchange structure of the cold box. A sensitivity analysis shows the effects of various parameters on the four combined exergy destruction forms of DHX tower, deethanizer, de-butane tower, which reveals that exergy destruction can be reduced by further improvement of condensate recovery process.
