Dual reheat rankine cycle system and method thereof

A method, comprising:

• circulating a working fluid in heat exchange relationship with a hot fluid via a heater to vaporize the working fluid;
• circulating a first vaporized stream of the working fluid from the heater in heat exchange relationship with a first condensed stream of the working fluid via a first heat exchanger of a hot system, thereby heating the first condensed stream of the working fluid to produce a second vaporized stream of the working fluid therefrom;
• and
• circulating the second vaporized stream of the working fluid from the hot system in heat exchange relationship with a second condensed stream of the working fluid via a second heat exchanger of a cold system to heat the second condensed stream of the working fluid before being fed to the heater.

A rankine cycle system, comprising:

• a heater configured to circulate a working fluid in heat exchange relationship with a hot fluid to vaporize the working fluid;
• a hot system coupled to the heater;
• wherein the hot system comprises a first heat exchanger configured to circulate a first vaporized stream of the working fluid from the heater in heat exchange relationship with a first condensed stream of the working fluid, thereby heating the first condensed stream of the working fluid to produce a second vaporized stream of the working fluid therefrom;
• and
• a cold system coupled to the heater and the hot system;
• wherein the cold system comprises a second heat exchanger configured to circulate the second vaporized stream of the working fluid from the hot system in heat exchange relationship with a second condensed stream of the working fluid to heat the second condensed stream of the working fluid before being fed to the heater;
• wherein the rankine cycle system is configured to produce the first condensed stream of the working fluid and the second condensed stream of the working fluid from a common condensing unit.
