Self-Powered Desalination of Geothermal Saline Groundwater: Technical Feasibility
This theoretical study shows the technical feasibility of self-powered geothermal desalination of groundwater sources at <100 °C. A general method and framework are developed and then applied to specific case studies. First, the analysis considers an ideal limit to performance based on exergy analysis using generalised idealised assumptions. This thermodynamic limit applies to any type of proce...
متن کاملPotential for Wind-Powered Desalination Systems in Jordan
Desalination systems driven by renewable energies are limited, and they usually have a limited capacity. They only represent about 0.02% of total desalination capacity. However, many reasons make the use of renewable energies suitable for brackish and seawater desalination. In addition to shortage of fresh water resources, Jordan is suffering from shortages in recoverable commercial energy sour...
متن کاملEntropy Generation of Desalination Powered by Variable Temperature Waste Heat
Powering desalination by waste heat is often proposed to mitigate energy consumption and environmental impact; however, thorough technology comparisons are lacking in the literature. This work numerically models the efficiency of six representative desalination technologies powered by waste heat at 50, 70, 90, and 120 ◦C, where applicable. Entropy generation and Second Law efficiency analysis a...
متن کاملSolar-thermal powered desalination: Its significant challenges and potential
Throughout the world, there are regions of vast extent that have many favorable features, but whose development is principally limited by the lack of fresh water. In arid areas where large-scale development has already occurred, e.g. parts of the Middle East and North Africa, the extraction of fresh water via desalination plants requires very large energy consumption. This motivates the develop...
متن کاملSolar-powered Desalination in a Remote Town in South Australia
Abstract: Coober Pedy is a remote town in South Australia with abundant solar radiation and scarce and low quality water, where a reverse osmosis plant has been operating since 1967. This paper evaluates the feasibility of powering the plant with solar or photovoltaic (PV) panels whilst avoiding energy storage in batteries. Pilot tests were performed in October 2005 with a small scale PV-powere...
