The average market price of granular ammonium sulfate ($138/ton) exceeds the rough estimated cost of ammonium sulfate from the proposed process ($111/ ton), by 25 percent, if granular size ammonium sulfate crystals of 1.2 to 3.3 millimeters in diameters can be produced by the proposed process.

MARKETABLE AMMONIUM SULFATE FERTILIZER AND FINE …

two marketable products, ammonium sulfate fe rtilizer and precipitated calcium carbonate (PCC), from wet limestone flue gas desulfurization (FGD) by-product gypsum. The wet FGD process, although effectively removing SO2 by using limestone, produces a large amount of solid gypsum. Power plants burning high-sulfur coal and using the FGD

Producing Ammonium Sulfate from Flue Gas Desulfurization ...

Dec 27, 2011 · High yields (up to 83%) of ammonium sulfate with up to 99% purity were achieved under relatively mild conditions. The optimal conversion condition was observed at 60°C and a 4-hour residence time. The results of this study indicate the technical feasibility of producing ammonium sulfate fertilizer from an FGD by-product.
