ABSTRACT:
A power generating system is powered by a circulating working fluid that is heated by heat of condensation deposited in a concentrated brine solution. The brine solution is concentrated by introducing a relatively dilute brine solution at a first location in a brine concentrator and collecting a relatively concentrated brine solution formed from the relatively dilute brine solution at a second location in the brine concentrator. A dry air flow is introduced at the second location and directed toward the first location to maintain a differential partial pressure between the air flow and the brine solution effective to evaporate solvent from the brine solution as the brine solution moves from the first location to the second location.
