Abstract:
Noble gases liquefying has an important application in industries. Different methods and Costs are up and a problem in industries. So, in this paper, the best cycle thermodynamically and economically was achieved by thermoeconomic analysis. For this purpose, first we investigated some applicable cycles and then chose liquefying cycle. Then thermoeconomic equations including exergy balance, entropy and energy balance were written for each component in order to optimize cycle. At last, thermodynamically and economically optimized values, were investigated. Performance coefficient values for dual pressure and pre-heated Linde Hampson cycles are achieved respectively by 2 and 1.8 times multiplying by simple cycle. Also the best performance coefficient of each compressor pressure ratio were evaluated in low ratios comparing to other pressure ratios. On the other hand it was illustrated that very low and very high pressure ratios are far from optimum circumstance and just for compressors we have the best efficiency in relatively low pressure ratios
