Sulfate Ion → Carbon Dioxide

Participants

Reaction Steps

oxidizing the regeneration bleed and then reacting the oxidized material in a first stage reactor with a calcium carbonate slurry, whereby alkali bisulfite is oxidized to alkali sulfate and sulfuric acid in the oxidation step and the sulfuric acid reacts with the calcium carbonate in the first stage reactor to produce calcium sulfate and carbon dioxide, which may be stripped off by an air stream fed to the bottom of the first stage reactor;
