sulfur dioxide is an acidic gas, it will dissolve to form sulfurous acid and eventually form sulfuric acid so it should be removed from any emissions before being discharged into the atmosphere, you could use any basic substance to remove it, as it will simply undergo a neutralisation reaction. Probably the cheapest substance would be lime (CaO) from the decomposition of calcium carbonate, or sodium hydrogen carbonate or even sodium hydroxide would remove it
