Summary This study develops a novel approach to reutilize cryogenic and thermal waste energy on a liquefied natural gas (LNG)‐powered passenger vessel. The waste energy is identified through a series of field tests of the LNG evaporation system and other important machinery systems, including the main engines, on a case ship. An Organic Rankine Cycle (ORC) power generation system is proposed to work between the LNG boiling temperature of −138°C (at 5 bar) and the waste heat temperature level of 400°C from the main engines' exhaust gas. The proposed ORC system is designed in terms of the field testing data and analyzed through simulation using Siemens LMS Imagine.Lab AMESim. Two different arrangements (single stage and 2 stages) of ORC are energetically, exergically, and economically analyzed. Three optimal working fluids are examined in high vacuum and above atmospheric condensing pressures in the temperature range of −110°C to 300°C. The proposed ORC systems are characterized by a significant improvement in thermal efficiency and power production in high vacuum condensing pressures. The 2‐stage ORC presents higher power output and fuel cost saving per year than the single‐stage ORC with almost the same payback time. The higher percentage of exergy destruction occurs at the evaporator of the ORC system. The increase in the exergy destruction on the condenser at higher condensing pressures contributes to the decrease of the exergy efficiency of the ORC systems.

“…The exergo-economics based analysis of thermodynamic processes considers the cost of exergy only not the entire cost of its elements (utility, equipment cost, labour cost, raw materials) for detailed economic analysis. The later approach has been reported to be used in the thermo-economic analysis of some thermodynamic systems which gives more realistic measure of performance such as in oil shale retorting processes with gas or solid heat carrier [34], lowgrade waste heat recovery in Yazd combined-cycle power plant by a CO 2 trans critical Rankine cycle [35], distillation based hybrid configurations for bioethanol refining [36], Organic Rankine cycle for exhaust waste heat recovery of a diesel engine [37], pressure swing adsorption process for bioethanol refining [38], combined supercritical CO 2 (carbon dioxide) recompression Brayton/organic Rankine cycle [39], ORCs (organic Rankine cycles) for low temperature waste heat recovery [40], milk spray dryer exhaust to inlet air heat recovery [41], Dual-purpose Power and Desalination Plants [42] and air energy storage (CAES) system integrated with a wind power plant in the framework of the IPEX market [43]. In addition, significant progress has been made in the design of hybrid system to convert the waste heat in PEMFC to electricity [44,45].…”

“…The estimated geothermal ORCs have an average SIC of 3156 € 2014 /kW for complete projects and 1149 € 2014 /kW for modules. The heat recovery ORC systems are more represented in the middle range, with estimated module costs around 2781 € 2014 /kW (Average calculated excluding the micro-scale diesel engine recovery ORC systems of Yang et al [46]. Including these gives an average heat recovery module SIC of 12,149 € 2014 /kW.)…”

Abstract:The potential of organic Rankine cycle (ORC) systems is acknowledged by both considerable research and development efforts and an increasing number of applications. Most research aims at improving ORC systems through technical performance optimization of various cycle architectures and working fluids. The assessment and optimization of technical feasibility is at the core of ORC development. Nonetheless, economic feasibility is often decisive when it comes down to considering practical instalments, and therefore an increasing number of publications include an estimate of the costs of the designed ORC system. Various methods are used to estimate ORC costs but the resulting values are rarely discussed with respect to accuracy and validity. The aim of this paper is to provide insight into the methods used to estimate these costs and open the discussion about the interpretation of these results. A review of cost engineering practices shows there has been a long tradition of industrial cost estimation. Several techniques have been developed, but the expected accuracy range of the best techniques used in research varies between 10% and 30%. The quality of the estimates could be improved by establishing up-to-date correlations for the ORC industry in particular. Secondly, the rapidly growing ORC cost literature is briefly reviewed. A graph summarizing the estimated ORC investment costs displays a pattern of decreasing costs for increasing power output. Knowledge on the actual costs of real ORC modules and projects remains scarce. Finally, the investment costs of a known heat recovery ORC system are discussed and the methodologies and accuracies of several approaches are demonstrated using this case as benchmark. The best results are obtained with factorial estimation techniques such as the module costing technique, but the accuracies may diverge by up to +30%. Development of correlations and multiplication factors for ORC technology in particular is likely to improve the quality of the estimates.
