Energy, exergy and economic analysis of a novel geothermal energy system for wastewater and sludge treatment

Alternative Fuels for Combined Cycle Power Plants: An Analysis of Options for a Location in India

“…Taken as a reference, 1990 emission limits of Greenhouse Gases (GHGs) concentrations should decrease to 50% until 2050 [1][2][3]. On this pathway, different policies have been defined in favor of energy production from clean sources [4][5][6] to support Sustainable Development Goals (SDGs) [7].…”

Thermal effects

“…A novel system for electric and thermal generation was proposed by Di Fraiaa, Macalusoa, Massarottia, and Vanoli (2019) to deal with the sewage sludge from energy, exergy, and economic perspective. The proposed system reduced the conveyance and disposition of 73% sludge and produced the electricity of 962 MWh every year, corresponding to 1.68 kWh electricity production in treating per kilogram sludge.…”

A preface to the special issue of optimization and engineering dedicated to SDEWES 2019 conference

“…The Water engineering problems have been addressed and studied by a number of papers, where the water-energy nexus has been most significantly investigated (Urbaniec et al 2016). The water-energy nexus studies investigated the desalination unit and the heat transfer inside of its preheater system (Hamid et al 2014), the geometry optimization of oscillating water column for wave energy converters (Ulazia, et al 2020), optimization of net power density in reverse electrodialysis (Ciofalo et al 2019), optimization of modular system for power generation from a salinity gradient (Altaee and Cipolina 2019), optimization of water-energy nexus in shale gas exploration (Oke et al 2019), optimization of a polygeneration system producing heat, cool and fresh water (Calise et al 2019), combining of the heat exchanger network and water network (Ahmetović et al 2014), and in the later study by Ibrić et al (2016), optimization of hot water production in different climates using solar thermal collectors (Kalogirou et al 2019), a novel geothermal energy system for wastewater and sludge treatment (Di Fraia et al 2019).…”
