Abstract
Direct contact hygroscopic condensation of water vapor on concentrated aqueous brine films, while simultaneously producing water vapor from adjacent water films flowing on the other side of the wall, is explored theoretically and experimentally. This process is the heart of an “internal” power cycle based on concentration differences and is driven by the difference in the partial pressures of the water in the brine and that of pure water. The basic thermodynamic limitations are derived, showing the advantage of the proposed internal direct-contact simultaneous condensation-evaporation process over the power cycle based on external heat transfer.
