| 摘要 |
Sulfur dioxide is removed from flue gas by scrubbing with an alkaline solution, the thus-absorbed sulfur salts being removed with a weak-base ion-exchange resin. On exhaustion, the resin is regenerated with an ammoniacal solution and the effluent treated with lime to precipitate insoluble sulfur salts and free ammonia. The liberated ammonia is then recycled as a resin regenerant. |
