An Analysis of Limestone Gypsum Desulfurization Systems

Abstract:

Limestone-gypsum desulfurization (LGD) technique is rather popular with the Electric Utility industries in their desulfuration operation. It’s been proved that, Control of PH Value and the concentration of gypsum may prevent scaling. Adoption of rubber or plastic linings based on the medium traits and the types of desulfuration system can prevent corrosion. Simple internal structure, control of pH Value of absorption liquid between 5.6 ~ 5.8, and limestone of the particle size ≤325 meshes particle above 90% may raise the efficiency of absorption tower, and promote its longevity. Control of the concentration of Chloride ion (Cl-) may guarantee a high quality of gypsum products.
