Abstract. The overall goal of this project is to assess the technical and economic feasibility for producing commercial-grade ammonium sulfate fertilizer from gypsum produced as part of limestone flue gas desulfurization (FGD) processes.
Calcium sulfate, which hydrates to become the common mineral gypsum, has a solubility of approximately 2000 mg/L as sulfate. Sulfate reduction below 2000 mg/L has been possible in the past only through expensive technologies such as reverse osmosis (RO) or ion exchange (IX).
Ammonium sulfate has a high sulfur content in the sulfate form, making it readily absorbable by plants. It has a low pH, making it suitable for alkaline soils. As a nitrogenous fertilizer, it competes with urea, ammonium phosphates, and ammonium nitrate.

Calcium from gypsum can help decrease volatilization loss of ammonium nitrogen from applications of ammonia, ammonium nitrate, UAN, urea, ammonium sulfate, or any of the ammonium phosphates. Calcium can decrease the effective pH by precipitating carbonates and also by forming a complex calcium salt with ammonium hydroxide which prevents ammonia .

Ammonium Sulfate WFGD Technology OVERVIEW FOR GENERAL INDUSTRY INFORMATION July 2007 Background Marsulex Environmental Technologies (MET) has developed an effective ammonia scrubbing technology that removes sulfur dioxide (SO 2) from boiler flue gases and produces high-value ammonium sulfate (AS) fertilizer.
Ammonium Sulfate - Swenson Technology. Production. Ammonium sulfate is made by treating ammonia, often as a by-product from coke ovens, with sulfuric acid: 2 NH3 + H2SO4 → (NH4)2SO4. Ammonium sulfate also is manufactured from gypsum (CaSO4·2H2O). Finely divided gypsum is added to an ammonium carbonate solution. Calcium carbonate precipitates.
manufacture of ammonium sulfate fertilizer from gypsum-rich by flue gas desulfurization (FGD)-gypsum to ammonium sulfate fertilizerhas .. for 300 days per year of operation, the plant produces 200,000 tons gypsum per year. ..Ammonium Sulfate, Encyclopedia of Chemical Processing and .
gaseous ammonia is used to react with SO3 gas to produce ammonium sulfate. Ammonium sulfate is then collected by a dry ESP. This method has been used commercially since the 1970s. However, as a high sulfur content in fuel means an elevated SO3 level in flue gas, the production of ammonium sulfate is subsequently increased.
