Abstract: A combustion turbine power plant (10) incorporating a water recovery apparatus (34). A sulfur stripper portion of the water recovery apparatus uses water (56) to remove suffer from the exhaust (20) of the combustion turbine (12) and to produce a reasonably high concentration of sulfuric acid for subsequent recovery of the sulfur. A water stripper portion (36) of the water recovery apparatus uses an aqueous solution of a desiccant (74) to absorb water from the exhaust gas. The wet desiccant may then be heated or exposed to a sub-atmospheric pressure in a regenerator (102) to recover the water. A sub-atmospheric regenerator may be maintained at a sufficiently high temperature by transferring waste heat from the exhaust gas. The resulting moisture content of the exhaust gas may be below that which can be achieved using traditional cooling heat exchangers.
