Abstract

A power plant may include a combustion apparatus (11) producing an exhaust gas (12), an absorber (20) receiving the exhaust gas (12), the absorber (20) including a desiccant and producing a first stream of desiccant solution containing water and a first concentration of desiccant, and an apparatus (29, 70, 94) for dehydrating the first stream of desiccant solution while maintaining the water in a liquid phase. The apparatus (29, 70, 94) may include a heat exchanger (71, 110), a crystallizing heat exchanger (74, 96), a separator (78, 98) and a flash tank (112) for dehydrating the desiccant solution while maintaining water in a liquid phase and subsequently recovering water from the solution.
