Distillation and condensation subsystem (DCSS) control in kalina cycle power generation system
First Claim
1. A method of operating a Kalina cycle power generation system, comprising the steps of:
- directing a stream of vaporized binary working fluid to a turbine;
expanding the vaporized binary working fluid in the turbine to produce power;
directing a first portion of the expanded binary working fluid to a distiller/condenser having multiple heat exchangers;
transforming the first portion of expanded binary working fluid using the multiple heat exchangers, 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, in the distiller/condenser;
directing at least the first concentration binary working fluid to a regenerative heat exchanger;
directing a second portion of the expanded binary working fluid to the regenerative heat exchanger;
transforming the first concentration binary working fluid into a vaporized binary working fluid and the second portion of expanded binary working fluid into a feed binary working fluid, in the regenerative heat exchanger;
directing the feed binary working fluid to a vapor generator;
vaporizing the feed binary working fluid in the vapor generator; and
actively regulating a binary working fluid flow within the distiller/condenser to maintain a relationship between the multiple heat exchangers.

Abstract
A method of operating a Kalina cycle power generation system, includes directing a stream of vaporized 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 having multiple heat exchangers where, using the multiple heat exchangers, 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 directed to a regenerative heat exchanger. A second portion of the expanded binary working fluid is directed to the regenerative heat exchanger where 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. The feed binary working fluid is directed to a vapor generator where it is vaporized. The binary working fluid flow within the distiller/condenser is actively regulated to maintain a desired relationship between the multiple heat exchangers.
