Abstract (en)
[origin: WO2019123243A1] A cascade process for the production of power from variable temperature heat sources, comprises: circulating a main working fluid selected from perfluorinated compounds (like Perfluoro-2-methylpentane/Perfluoro-i-hexane) in a main circuit (2) according to a main supercritical organic Rankine cycle, operatively coupling in a boiler (4) a variable temperature heat source (9) with the main working fluid of the main circuit (2) to heat and vaporize the main working fluid; circulating an auxiliary working fluid in an auxiliary circuit (3) according to an auxiliary Rankine cycle; thermally coupling in cascade the expanded main working fluid of the main Rankine cycle with the auxiliary working fluid of the auxiliary Rankine cycle, in order to cool the main working fluid and heating the vaporizing the auxiliary working fluid by heat transfer from the main Rankine cycle to the auxiliary Rankine cycle before the expansion of the auxiliary working fluid in an auxiliary expander (12).
