Ammonium Sulfate Fertilizer From Fgd Gypsum

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.

Ammonium sulfate is a mixed fertilizer which contains nitrogen and sulfur nutrients (FAO, 2003, Tisdale, 2002). The ammonium sulfate provides the ideal solution that has a quick sulfate release tied in with the season-long availability of degradable sulfur (Hoeft et al., 1985, Dudal, 2002).

Gypsum is not acid soluble and will not change the soil pH. It helps to shift the Ca and Mg levels in soil and offers a readily available form of sulfate sulfur, a valuable secondary nutrient that benefits the soil and crop. The sulfate in gypsum binds with excess Mg in the soil to form soluble Epsom salt, which moves lower into the soil profile.

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.

Dry, powdered ammonium sulfate may be formed by spraying sulfuric acid into a reaction chamber filled with ammonia gas. The heat of reaction evaporates all water present in the system, forming a powdery salt. Approximately 6000M tons were produced in 1981. Ammonium sulfate also is manufactured from gypsum (CaSO 4 ·2H 2 O).
