A method is described for utilizing sensible heat energy supplied by a high-temperature heating fluid for power generation, employing a multi-component working fluid thermodynamic cycle, wherein a solution having a higher concentration of lower boiling component or components (hereinafter ''rich solution'') is heated in a vapor generator in counter-current heat exchange with the heating fluid to produce a vapor-liquid mixture which is introduced into a lower zone of a rectifier and separated therein into a solution having a lower concentration of the lower boiling component or components (hereinafter ''lean solution'') and a vapor mixture; the enthalpy of the vapor mixture in counter-current heat exchange with the heating fluid at its highest temperature; the vapor mixture is then expanded to a low pressure level thereby to perform the function of the cycle; and the spent vapor mixture is introduced into an absorber wherein it is dissolved in the lean solution, under heat rejection to an external coolant, so as to regenerate a rich solution.
