Abstract

L’invention concerne un procédé de production d’énergie électrique mettant en œuvre au moins un premier cycle de Rankine et un deuxième cycle de Rankine, ledit premier cycle de Rankine comprenant la vaporisation d’au moins une partie dudit premier fluide de travail (W1) contre au moins un premier courant chaud (C1), puis la détente du premier fluide de travail (W1) dans un premier organe de détente coopérant avec un premier générateur électrique de façon à produire de l’énergie électrique, la condensation d’au moins une partie dudit premier fluide de travail (W1) contre au moins un premier courant froid (F1), l’élévation de la pression dudit premier fluide de travail (W1) jusqu’à la première pression (Ph1) et fermeture du premier cycle, et le deuxième cycle de Rankine comprenant la vaporisation d’un deuxième fluide de travail (W2) contre au moins un deuxième courant chaud (C2), la détente du deuxième fluide de travail (W2) dans un deuxième organe de détente coopérant avec un deuxième générateur électrique de façon à produire de l’énergie électrique, la condensation d’au moins une partie dudit deuxième fluide de travail (W2) contre au moins un deuxième courant froid (F2), l’élévation de la pression dudit deuxième fluide de travail (W2) et fermeture du deuxième cycle. Selon l’invention, le premier courant froid (F1) du premier cycle forme le deuxième courant froid (F2) du deuxième cycle. Figure de l’abrégé : Fig. 2The invention relates to a method for producing electrical energy implementing at least a first Rankine cycle and a second Rankine cycle, said first Rankine cycle comprising the vaporization of at least a part of said first working fluid (W1 ) against at least a first hot current (C1), then the expansion of the first working fluid (W1) in a first expansion member cooperating with a first electric generator so as to produce electrical energy, the condensation of at at least a portion of said first working fluid (W1) against at least a first cold stream (F1), raising the pressure of said first working fluid (W1) to the first pressure (Ph1) and closing the first cycle , and the second Rankine cycle comprising the vaporization of a second working fluid (W2) against at least a second hot stream (C2), the expansion of the second working fluid (W2) in a second expansion member cooperating with a second g electrical generator so as to produce electrical energy, condensing at least part of said second working fluid (W2) against at least a second cold stream (F2), raising the pressure of said second working fluid (W2) and closing the second cycle. According to the invention, the first cold current (F1) of the first cycle forms the second cold current (F2) of the second cycle. Figure of the abstract: Fig. 2
