Thesis COMPARACIÓN DE SISTEMA SOLAR TÉRMICO CON SOLAR FOTOVOLTAICO PARA REGULAR TEMPERATURA DE ELECTROLITO EN SISTEMA DE ELECTRORREFINACIÓN DE METALES(Universidad Técnica Federico Santa María, 2015) SOTOMAYOR GONZALEZ, CLAUDIO ANDRÉS; KOURO RENAER, SAMIR FELIPE; Universidad Tecnica Federico Santa Maria UTFSM DEPARTAMENTO DE ELECTRONICA; ROJAS MONRROY, CHRISTIANCHILE is a country whose incomes are obtained mainly from mining process, where the electrore ning plant is part of the productive process. Conventionally, this process depends on the energy obtained directly from the AC main. An important part of the energy is used to heat the electrolytic solution, due to it requires a constant temperature to optimize the copper extraction through the electrolisis process. The reached development in the use of renewable energy and its cost reduction, particulary in solar energy is high in the last years. Furthermore, most of electrore ning plants are located in the north of Chile, where the irradiance levels are very high. For those reasons, fed these types of plants with solar energy may be result a bene t to the mining industry and a reduction of foil combustibles and its eects. This research proposes an electrore ning plant fed by solar modules to heat the electrolitic solution in parallel to the Ac main, where the modelling of the thermal plant and electronic solar plant is needed. The use of power converters allow to obtain the maximum power from the solar modules, furthermore to heat the solution is needed only DC current, then the possibility to use only dc-dc converters can reduce the looses avoiding the use of bulky transformers, recti ers and transmissions lines.
