Thermoeconomic analysis of oil shale retorting processes with gas or solid heat carrier

Thermo-economic analysis of proton exchange membrane fuel cell fuelled with methanol and methane

“…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].…”

Framework for advanced exergoeconomic performance analysis and optimization of an oil shale retorting process

“…The process simulator Aspen Plus was used to simulate the whole system. This simulator is widely used in modeling and simulation of chemical and energy conversion systems [6,37]. The simulation results obtained should be validated against industrial data [38], after which the models used and the results of the simulation can be applied in system analysis and optimization.…”

“…In this paper, the standard exergies of oil shale ðe q os Þ and shale oil ðe q so Þ are calculated for low ðDh q L Þ and high ðDh q H Þ heating values of shale oil [61]. They are formulated as follows [6,61]:…”

“…For example, Gao et al [4,5] adopted conventional exergy analysis to evaluate a coal based polygeneration process, and Li et al [6] applied conventional exergy analysis to compare three typical oil shale retorting processes. Conventional exergy analysis, however, only allows identification of the location and magnitude of the inefficiencies; it neither offers data on the efficiency of interactions between the components, nor provides detailed information about the potential for improvement of the components [7].…”

Advanced exergy analysis of an oil shale retorting process

“…However, little work has been done to model and simulate the complete FsOSR process, and there is a lack of research analyzing the thermodynamic performance of the whole FsOSR process. Li et al [15] used conventional exergy analysis to analyze and compare three typical retorting technologies: the FsOSR, the gas full-circulation retorting process, and the Dagong retorting method. The obtained results showed that the FsOSR technology had the biggest exergy destruction ratio, 65.7%.…”
