ABSTRACT:
A waste flue gas desulfurizing method in which a waste flue gas containing sulfurous acid gas is contacted directly with sea-water, whereby the sulfurous acid gas is absorbed in the sea-water and concurrently sulfites are formed in the sea-water by the reaction between the sulfurous acid ions and metal ions present in the sea-water, and then the carbonic acid component contained in the sea-water which is then in the acidic region is released therefrom by a decarbonation operation to restore the pH value of the sea-water in the neutral region, and thereafter oxygen contained in air or from other source is introduced into the sulfite-containing sea-water to convert said sulfites into sulfates.
