Low-temperature geothermal heat sources have the highest share of energy in world. Utilization these for and freshwater generation can play an important role meeting demands. To do so, this study aims to propose a novel trigeneration cycle powered by low-temperature sources. The proposed system, which is integration Kalina humidification-dehumidification (HDH) cycles, used electricity, heating,...

method of thermoeconomic optimization separate section a typical sugar plant. was developed. Since the main part exergy losses is due to heat transfer at finite temperature difference, value drop in each s chosen as an independent variable with corresponding search for their minimum costs. The existence local fact that increasing increases amount energy costs (because increase) and decreases ca...

The anaerobic digestion of the organic fraction municipal solid waste and biogas production obtained from its stabilization are becoming an increasingly attractive solution, due to their beneficial effects on environment. In this way, is considered a resource allowing reduction in quantity it going landfills derived greenhouse gas emissions. Simultaneously, upgrading process into biomethane can...

This study presents a thermal and economic performance analysis of a LT-MEE (low-temperature multieffect evaporation) water desalination system coupled with an LiBreH2O ABHP (absorption heat pump). A 60e78% water production increase over a stand-alone LT-MEE run at the same heat source conditions can be obtained owing to the coupling. A detailed thermodynamic sensitivity analysis of the ABHP-ME...

Incorporation of ecological considerations in decision-making is essential for sustainable development, but is hindered by inadequate appreciation of the role of ecosystems, and lack of scientifically rigorous techniques for including their contribution. This paper develops a novel thermodynamic accounting framework for including the contribution of natural capital via thermodynamic input-outpu...

A large number of resources are dedicated to seawater desalination and will only grow as world-wide water scarcity increases. In arid areas with high temperature and salinity seawater, thermal desalination and power plants (dual-purpose/co-generation plants) are often employed for the production of power and water. In other areas, reverse osmosis is commonly employed. However, both technologies...

Hybrid solar and geothermal utilisation is a promising option for effective exploitation of renewable energy sources. Concentrated power (CSP) systems with preheating are acknowledged as an attractive solution, supercritical CO2 (SCO2) cycle adopted generation thanks to the favourable properties offered by working fluid. In order further improve overall performance such systems, organic Rankine...
