Abstract
A method of operating a Kalina cycle power generation system, includes directing a stream of superheated binary working fluid to a turbine where it is expanded to produce power. A first portion of the expanded binary working fluid is directed to a distiller/condenser where it is transformed into a first concentration binary working fluid, having a first concentration of a component of the binary working fluid, and a second concentration binary working fluid, having a second concentration of the component. At least the first concentration binary working fluid is directed to a regenerative heat exchanger. A second portion of the expanded binary working fluid is also directed to the regenerative heat exchanger. The first concentration binary working fluid is transformed into a vaporized binary working fluid and the second portion of expanded binary working fluid is transformed into a feed binary working fluid in the regenerative heat exchanger. The feed binary working fluid is directed to a vapor generator where it is vaporized. The second concentration binary working fluid is combined with the vaporized feed binary fluid to form the superheated binary working fluid. The flow of binar…
