Abstract (en)
[origin: WO02087722A1] The invention relates to an economical method and devices for obtaining distillate-quality drinking water and high-percentage brine containing varying amounts of salt. Combined with a thermal power generation process, the system also provides electric current with a fuel utilization rate of more than 85 %. The inventive method uses waste heat and works with an evaporation-saturated air circulation system over a temperature interval with recuperative pre-warming of untreated water. Said systems can consist of a very large number of evaporation modules and can therefore be adapted to all drinking water requirements. The evaporation modules work in up to 4 system pressure stages and can use waste heat from the higher ranking system pressure stages in the pressure stages disposed downstream therefrom. Heat consumption values of less than 10 kWh/m<3> of drinking water can thus be obtained. The modular design can meet capacities of 3.0 -1000 m<3>/h drinking water using standard gas turbines/generator sets. Smaller amounts of drinking water can be obtained by using the waste heat from internal combustion engines.
