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.
Proprietary to and Patented by Marsulex Environmental Technologies In the Ammonium Sulfate (AS) process, the absorption of SO 2 is accomplished with either anhydrous or aqueous ammonia and converts the captured SO 2 into a high value crop fertilizer. This advanced technology provides a unique solution enabling power generators to achieve regulatory compliance producing significant revenues .
DR.James G. Speight, in Environmental Inorganic Chemistry for Engineers, 2017. 3.3.4 Ammonium Sulfate. Ammonium sulfate ((NH 4) 2 SO 4) is an inorganic salt with a number of commercial uses.The most common use is as a soil fertilizer since the chemical contains 21% .
The new process takes waste gypsum or chalk and purifies it so that it can be used as high-grade white filler in plasterboard and cement. Firstly, impure gypsum is placed into a solution of ammonium sulfate around 90–100°C, together they form a complex. This complex sinks into the solution, releasing any impurities in the gypsum.
Gypsum (calcium sulfate) The least expensive option, gypsum, made up of calcium sulfate, is an excellent soil amendment for soils that are deficient of both calcium and sulfur. Gypsum contains 15% sulfate, which is the only absorbable form of sulfur for plants. Manure
ammonium sulfate production from gypsum. Sales Inquiry Ammonium Sulfate Production From Gypsum; USGS Fact Sheet: Coal Combustion Products Sulfate is the preferred form of sulfur readily assimilated by crops, and ammonium sulfate is the ideal sulfate compound for soil supplements because it also provides nitrogen from the ammonium.
The sulfate content of the wastewater can be lowered to 4000 to 5000 mg/L, with the resulting gypsum easily dewatered in a filter or belt press. Approximately 1.8 pounds of gypsum are precipitated per pound of sulfate. Since this is pure gypsum, no special handling or disposal permits are required. Step 2 -- Metal Hydroxide Precipitation
