This work evaluates the performance regarding exergo-economic and emissions requirements of Waste Heat Recovery configurations (Organic Rankine cycle, Trilateral flash Kalina cycle) under different operating conditions working fluids. It was found that best economic is presented by Organic cycle operates with Cyclo-Pentane has two intermediate heat exchangers since it pushes expansion temperatu...

Hybrid renewable energy systems (HRES) combine two or more and are an interesting solution for decentralized generation. The exergy exergo-economic approach have proven to be useful methods analyze hybrid systems. aim of this paper is present a review exergy-economic approaches evaluate in buildings. In the first part paper, methodology analysis introduced as well main performance indicators. i...

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...

Major objectives of this study were to produce low-emitting wood pellet biofuel from selected agro-forest tree species, i.e., Kikar (Acacia nilotica), Oak (Quercus semicarpifolia), and Mesquite (Prosopis juliflora), grown in the southern part Khyber Pakhtunkhwa (KP) province Pakistan using indigenously developed technology (pelletizer machine). Primary raw material, such as sawdust was obtained...

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...
