Sulfate Removal Technologies A Review
The CESR process requires lime addition and a pH of about 11.3 for ettringite formation, and can achieve sulfate concentrations far below the gypsum solubility limit (Reinsel, 2001). Sulfate concentrations are typically limited only by the amount of reagent added and reaction time. Disadvantages are the large amount of sludge generated, and the fact that high sodium concentrations inhibit the

FGD Gypsum Production Process – Gypsum Association
FGD Gypsum Production Process. Mineralogically identical to natural gypsum, FGD gypsum, or synthetic gypsum, is produced from gas captured within emission control systems at coal fired electric utilities. An emission that would compromise air quality, sulfur dioxide (SO 2) gas, is the primary contribution coal makes to FGD gypsum.

Dry Scrubber
However, washing the FGD gypsum, as is commonly done for wallboard grade gypsum, would remove most of the halogens. For spray dryer-based dry FGD systems, the presence of elevated halogen levels in the flue gas will alter droplet drying characteristics, due to the deliquescent nature of the calcium salts of these halogen acids.
