Understanding the drying kinetics within a food dryer is an important step towards its improvement. This study investigates of potato slices in recently proposed waste-heat based convective dryer. Statistical analyses are conducted for ten dissimilar mathematical models to choose best fit model experimental data at various temperatures (70 °C, 60 and 50 °C). Results show that Midilli et al. des...

This paper aims to present the real improvement opportunities of a simple organic Rankine cycle (ORC) as waste heat recovery system (WHRS) from exhaust gases natural gas engine using toluene working fluid, based on exergy and environmental point view. From energy balances, advanced exergetic analysis was developed determine irreversibilities for improvement. Since traditional exergo-environment...

Geothermal energy is a clean resource, which could significantly contribute to the reduction of greenhouse and other gas emissions by replacing fossil fuels for power generation. In many geothermal sites, resource contains substantial Non-Condensable Gases (NCGs: CO2 contaminants), whose can be limited developing plant schemes suitable complete reinjection. Organic Rankine or closed-loop cycles...

This research presents the energy, exergy, economic, and environmental assessment, multi-objective optimization of a flash-binary geothermal CCHP cycle. A sensitivity analysis production well inlet temperature cooling to power flow ratio on exergetic, parameters was conducted. Furthermore, effects inflation rate plant working hours economic were investigated. Results showed that increasing harm...

This study deals with the life cycle assessment (LCA) and an exergo-environmental analysis (EEvA) of geothermal Power Plant Hellisheiði (Iceland), a combined heat power double flash plant, installed 303.3 MW for electricity 133 hot water. LCA approach is used to evaluate analyse environmental performance at plant global level. A more in-depth developed, components level, through EEvA. The emplo...
