| Abstract: | Performance analysis was taken for heat exchangers with the method of exergy analysis.The formula for completely evaluating heat exchangers was figured out.Energy utilization analysis was taken for heat exchangers of benzene production in producing of aromatic hydrocarbon,and exergy efficiency,exergy loss,exergy benefit per square meter and the new indicator were derived.The results showed heat exchangers with fluid phase change had better performance than those of single phase fluid. |
