Manufacture of ammonium sulfate fertilizer from gypsum ...

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 from the proposed process

FINAL TECHNICAL REPORT - ISGS

Conversion of FGD-gypsum to ammonium sulfate was tested at temperatures between 60 to 70°C for a duration of four to six hours. A preliminary process flow diagram was proposed, and the economics of the process was estimated. The preliminary data indicated that only when the particle size of a fertilizer grade of ammonium sulfate crystals could ...

The authors have been developing a process which converts FGD-gypsum to ammonium sulfate fertilizer with precipitated calcium carbonate as a by-product during the conversion. Preliminary cost estimates suggest that the process is economically feasible when ammonium sulfate crystals are produced in a granular size (1.2 to 3.3 mm), instead of a powder form.
