Abstract
Flue gas containing sulfur dioxide, carbon dioxide and other acidic components is desulfurized by washing it with an aqueous washing solution to which ammonia has been added in the stoichiometrically necessary amount for reaction with the sulfuroxides. The addition of the ammonia is so controlled that a predetermined amount of ammonium carbonate is maintained in the washing solution.
