実験手順
In a process for desulfurizing a sulfur dioxide-containing gas stream where the gas stream is contacted, in a wet scrubbing unit, with an aqueous solution of magnesium scrubbing components which react with sulfur dioxide to form magnesium sulfite and magnesium bisulfite, and a portion of the resultant aqueous solution containing magnesium sulfite and magnesium bisulfite is removed from the wet scrubbing unit and oxidized in an oxidizing unit to form an aqueous solution of magnesium sulfate containing a minor amount of about 500-600 ppm of magnesium bisulfite and magnesium sulfite as impurities, with the aqueous solution of magnesium sulfate contacted with lime to form calcium sulfate, which is removed therefrom, and an aqueous suspension of magnesium hydroxide containing a minor amount of calcium sulfite which is returned to the wet scrubbing unit, the improvement comprising:
