Summary Report, Sulfur Oxides Control Technology Series

Gypsum presents a greater scaling problem than does the calcium sulfite/sulfate coprecipitate. Gypsum forms a hard scale that is difficult to remove. Sulfite/sulfate coprecipitate scale can be removed easily by a lowered pH, which causes the scale to dissolve. The process was also the first stack-gas desulfurization technology used in the
