<p>This invention is a combination process for removal of sulfur oxides (SOx) from gases containing both the SOx and oxygen (106). The fluid used to remove the SOx contains sulfuric acid and bromine. The SOx is converted to sulfuric acid and the bromine is thereafter converted to hydrobromic acid. The hydrobromic acid is concentrated and catalytically converted to bromine for ultimate recycling to the SOx removal step (132). The SOx is finally recovered as a strong sulfuric acid (104).</p> |
