Abstract

Un procédé et un dispositif pour l'utilisation de la vapeur souterraine supercritique (SC) en combinaison avec des centrales thermiques et hydrauliques supercritiques avec un rendement de 50% utilisent la technologie de forage super-profond en bain métallique fondu, le procédé HydroFrac, et les propriétés particulières de la vapeur souterraine supercritique, telles que l'augmentation drastique de la capacité thermique, la réduction de la viscosité et la solubilité inorganique. L'utilisation multifonctionnelle de ces technologies et des propriétés physiques de la vapeur souterraine supercritique dans le procédé selon l'invention permet la mise en exploitation rapide et économique d'un échangeur de chaleur à vapeur souterraine SC à grande profondeur, tout en rendant possible la production d'électricité, d'énergie, de vapeur de traitement et de chaleur, presque partout, avec réduction des coûts d'un dixième par rapport aux coûts des technologies conventionnelles au fuel, dans des conditions de dépense comparables. La vapeur de traitement supercritique obtenue au moyen d'un circuit forcé fermé "géo-nature" souterrain est utilisée dans des centrales supercritiques, en ayant recours à des technologies classiques de pointe de turbines à vapeur, cependant que la pression restante dans le fluide souterrain est utilisée pour la production directe d'énergie et/ou de courant électrique après dissipation de chaleur par les turbines hydrauliques.
