Recycling of FGD gypsum to calcium carbonate and

A combined chemical and biological process for the recycling of flue gas desulfurization (FGD) gypsum into calcium carbonate and elemental sulfur is demonstrated. In this process a mixed culture of sulfate-reducing bacteria (SRB) utilizes sewage digest as its carbon source to reduce FGD gypsum to hydrogen sulfide. The sulfide is then oxidized to elemental sulfur via reaction with ferric

Three Factors Affect Limestone Desulfurization Efficiency

 · Generally the content of calcium carbonate in limestone should be above 85 . If the calcium carbonate content is too low it will cause some problems for the desulfurization because of the impurities in limestone leading to the increase of absorbent consumption and transportation cost. The quality of limestone is decided by the content of CaO.
