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 d’un premier fluide de travail (W1) contre au moins un premier courant chaud (C1), la détente du premier fluide de travail (W1) dans un premier organe de détente coopérant avec un générateur électrique de façon à produire de l’énergie électrique, puis la condensation d’au moins une partie dudit premier fluide de travail (W1) contre au moins un premier courant froid (F1) puis élévation de pression dudit premier fluide de travail (W1) et fermeture du premier cycle. Le deuxième cycle de Rankine comprend la vaporisation d’au moins une partie d’un deuxième fluide de travail (W2) contre au moins un deuxième courant chaud, la détente jusqu’à une deuxième pression basse Pb2 dans un deuxième organe de détente coopérant avec un générateur électrique de façon à produire de l’énergie électrique, puis la condensation d’au moins une partie dudit deuxième fluide de travail (W2) contre au moins un deuxième courant froid (F2), puis élévation de pression et fermeture du deuxième cycle. Selon l’invention, le deuxième courant chaud du deuxième cycle de Rankine est formé au moins en partie par le premier fluide de travail (W1) condensé dans le premier cycle de Rankine et le premier courant froid (F1) est formé par le deuxième courant froid (F2) issu du deuxième cycle de Rankine. Figure de l’abrégé : Fig. 3The invention relates to a method of 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 a first working fluid (W1) against at least a first hot current (C1), the expansion of the first working fluid (W1) in a first expansion member cooperating with an electric generator so as to produce electrical energy, then the condensation of at least a part of said first working fluid (W1) against at least a first cold stream (F1) then raising the pressure of said first working fluid (W1) and closing the first cycle. The second Rankine cycle comprises the vaporization of at least a part of a second working fluid (W2) against at least a second hot current, the expansion down to a second low pressure Pb2 in a second expansion member cooperating with an electric generator so as to produce electric energy, then the condensation of at least part of the said second working fluid (W2) against at least a second cold current (F2), then pressure rise and closure of the second cycle . According to the invention, the second hot stream of the second Rankine cycle is formed at least in part by the first working fluid (W1) condensed in the first Rankine cycle and the first cold stream (F1) is formed by the second stream cold (F2) from the second Rankine cycle.
