Patent ID: 8555643

Claim:
A method for implementing a thermodynamic cycle comprising: expanding a fully vaporized and superheated third saturated vapor stream, transforming a portion of thermal energy into a usable form in a turbine assembly to form a spent stream; mixing the spent stream with a third reduced mixed liquid-vapor stream to form a basic solution stream, condensing the basic solution stream in a condenser or first heat exchange unit using an external coolant to form a fully condensed basic solution stream, pressurizing the fully condensed basic solution stream to form a pressurized basic solution stream, mixing the pressurized basic solution stream with a first saturated vapor stream to form a first or once enriched stream, where the pressurized basic solution stream fully absorbs the once saturated vapor stream, pressurizing the once enriched stream to form a pressurized enriched stream, partially vaporizing the pressurized enriched stream in a second heat exchange unit using heat from a cooled external heat source stream to form a partially vaporized enriched stream and a spent external heat source stream, separating the partially vaporized enriched stream in a first separator to form the third saturated vapor stream and a first lean liquid stream, fully vaporizing and superheating the third saturated vapor stream in a third heat exchange unit to form the fully vaporized and superheated third saturated vapor stream, reducing the pressure of the first lean liquid stream via a first throttle valve to form a first reduced pressure mixed liquid-vapor stream, feeding the first reduced pressure mixed liquid-vapor stream into a third separator to form the first saturated vapor stream and a third lean liquid stream, and reducing the pressure of the third lean liquid stream via a third throttle valve to form the third reduced pressure mixed liquid-vapor stream, where all of the stream are derived form a multi-component working fluid.
