Abstract
A method of operating a power generation system is provided. The system includes a turbine, a distiller/condenser, a boiler, and a superheater. The turbine expands a superheated multicomponent working fluid to produce power. The distiller/condenser transforms the expanded multicomponent working fluid into first and second concentration multicomponent working fluids. The first concentration multicomponent working fluid has a first concentration of a component of the multicomponent working fluid. The second concentration multicomponent working fluid has a second concentration of the component which is different than the first concentration. The boiler vaporizes a feed multicomponent working fluid. The superheater superheats the vaporized feed multicomponent working fluid to form the superheated multicomponent working fluid. In operating the system, the temperature of the vaporized multicomponent working fluid is sensed. The first and second concentration multicomponent working fluids are combined to form a third concentration multicomponent working fluid. The third concentration multicomponent working fluid has a third concentration of the component which is different than the first and second concentrations. The third multicomponent working fluid is combined with the vaporized multicomponent working fluid to adjust the temperature of the vaporized multicomponent working fluid and thereby regulate the temperature of the superheated multicomponent working fluid.
