A new Kalina thermodynamic cycle is disclosed where a multi-component working fluid is fully vaporized in a boiler utilizing waste heat streams such as flue gas streams from cement kilns so the energy can be extracted from the streams and converted to usable electrical or mechanical energy in a turbine subsystem and after extraction, the spent stream is fully condensed in a distillation-condensation subsystem using air and/or water coolant streams. A new method for implementing the improved Kalina thermodynamic cycle is also disclosed.
