摘要： This process avoids the disadvantages of admixing hot molten ammonium bisulfate with ammonium sulfites solutions. Overflowing hot molten ammonium bisulfate is admixed with a stream of aqueous ammonium bisulfate solution, said solution being preferably circulated in a closed loop. A portion of the resulting solution is then used to acidify the ammonium sulfites solution.

摘要： A SO.sub.2 containing gas, for example a stack gas, is purified according to a multi-step process, which comprises washing said gas with an aqueous ammonia solution, treating the resulting solution with hydrochloric acid, whereby SO.sub.2 and an aqueous ammonium chloride solution are obtained and separated. The ammonium chloride solution is then reacted with magnesium oxide to recovery ammonia and the resulting magnesium chloride is cracked to produce hydrochloric acid and magnesium oxide, the ammonia, hydrochloric acid and magnesium oxide being recycled to the process.
