The solubility of ammonia in water exceeds 20%. Synthetic ammonia process is rich in raw materials. Ammonia process takes ammonia as raw material, and its forms can be liquid ammonia, ammonia water and ammonium bicarbonate. At present, the annual emission of sulfur dioxide from thermal power plants in China is about100000 tons. Even if all desulfurization by ammonia method is adopted, the ammonia consumption will not exceed 5 million tons/year, and the supply is completely guaranteed. The biggest feature of ammonia method is that
The recovery of SO2 can recycle the pollutant SO2 into commodities with high added value. By-product ammonium sulfate is a kind of nitrogen fertilizer with excellent performance and has a good market prospect in China.
