Costs for constructing and operating a conceptual plant based on a proposed process that converts flue gas desulfurization (FGD)-gypsum to ammonium sulfate fertilizer has been calculated and used to estimate a market price for the product. The average market price of granular ammonium sulfate ($138/ton) exceeds the rough estimated cost of ammonium sulfate

Dec 31, 1995· FGD-gypsum from Abbott power plant was used. The scrubber, a Chiyoda Thoroughbred 121 FGD, produced a filter cake (98.36% gypsum and < 0.01% CaSO {sub 3}). Conversion of FGD- gypsum to ammonium sulfate was tested at 60-70 {degree}C for 5-6 hr. Yield up to 82% and purity up to 95% were achieved for the ammonium sulfate production.

Gypsum has historically been used in crop production as a soil amendment, where calcium is needed to reclaim sodic soils. One provides nitrogen, and the other provides calcium. Sulf-N ammonium sulfate is a readily-available source of sulfur that also supplies 21 units of nitrogen in the highly-stable ammonium form.
