The relations between capital costs and thermodynamic losses for the devices in the system are investigated. Thermodynamic loss rate-to-capital cost ratios are used to show that, for the devices and the overall system, a systematic correlation appears to exist between capital cost and exergy loss (total or internal), but not between capital cost and energy loss or external exergy loss. This correlation may imply that devices in a successful industrial pasta drying system is configured so as to achieve an overall optimal design, by appropriately balancing the thermodynamic (energy- and exergy-based) and economic (cost) characteristics of the overall system. Thermodynamic loss rate to capital cost values Ren and Rex are obtained as 0.016-0.004, while total energy rate input value to system change between 304.85 and 316.25 kW. Energetic and exergetic efficiencies of the system processes are determined in an attempt to assess their individual performances. The energy and exergy efficiencies of the overall system are found to be as 72.1 and 65.4 per cent, respectively. © IMechE 2007.EnglishCorrelation methodsCostsDryingEconomic analysisEnergy dissipationEnergy efficiencyExergyThermodynamicsCorrelation methodsCostsEconomic analysisEnergy dissipationEnergy efficiencyExergyThermodynamicsExergy efficiencyThermo-economic analysisThermodynamic lossDryingArticle10.1243/09576509JPE481
