·Ammonia recovery rate ≥ 99%

gas system

The flue gas enters the desulfurization absorption tower, undergoes cooling, washing, and defogging, and then enters the chimney to meet emission standards.

Absorption system

The absorbed ammonium bisulfite is oxidized to ammonium sulfate, and the ammonium sulfate solution lowers the temperature of the flue gas and evaporates water, further increasing its own concentration.

Ammonium sulfate system

Using the saturated crystallization process, the absorption system produces a certain solid content of ammonium sulfate slurry, which is then subjected to solid-liquid separation, drying, and packaging to produce commercial ammonium sulfate; The use of evaporative crystallization technology involves setting up an evaporative crystallization system to evaporate and crystallize the ammonium sulfate solution produced by the absorption system, followed by solid-liquid separation, drying, and packaging to produce commercial ammonium sulfate.
