A method of removing sulfur oxides from flue gas produced by the combustion of a fuel to produce a flue gas containing sulfur oxides and water comprising contacting the moist flue gas with hydrated alkaline earth metal hydroxide particles having a temperature sufficiently low to condense the water vapor present in the flue gas onto the particles and recovering a flue gas reduced in sulfur oxides.
