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 4hour residence time. The results of this study indicate the technical feasibility of producing ammonium sulfate fertilizer from an FGD byproduct.
A continuous countercurrent flow process for converting FGD gypsum to ammonium sulfate and calcium carbonate including countercurrent flows with internal recycle of liquids to maximize the purity of reaction products while minimizing reaction times, and further include embodiments of the process that provide a yield of both ammonium sulfate and calcium carbonate to be 97 to , and ...
Millions of tone of FGDgypsum byproduct may be produced in this decade as a result of the 1990 Clean Air Act Amendments. In this research, benchscale experiments were conducted to obtain process data for the production of ammonium sulfate from FGDgypsum and to help evaluate technical and economic feasibilities of the process.
of FGDgypsum to ammonium sulfate and PCC becomes an attractive process that could improve the economics of FGD systems in Illinois. The overall goal of this project is to assess the technical feasibility for producing the dual commercial products, ammonium sulfate fertilizer and PCC, from FGDgypsum. Specific objectives of this phase of study ...
Manufacture of ammonium sulfate fertilizer from gypsumrich . Mar 12, 2012 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 .
The authors have been developing a process which converts FGDgypsum to ammonium sulfate fertilizer with precipitated calcium carbonate as a byproduct during the conversion. Preliminary cost estimates suggest that the process is economically feasible when ammonium sulfate crystals are produced in a granular size ( to mm), instead of a powder form.

ammoniumsulfate 115 Ammonium Sulfate ( Ammonium Tetraoxosulfate(VI), Mascagnite) is an inorganic salt with brownish to white crystal solid appearance (depending on the purity), odorless, soluble in water and insoluble in most organic solvents.
Manufacture of ammonium sulfate fertilizer from FGDgypsum OSTI. The overall goal of this project is to assess the technical and economic feasibility for producing fertilizergrade ammonium sulfate from gypsum produced as part of limestone flue gas desulfurization (FGD) processes.
[5]: gypsum, elemental sulfur, concentrated SO 2, sulfuric acid and ammonium sulfate (nitrogen fertilizer, abbreviated as Nfertilizer). Considering the commercial value of fertilizer in domestic and international markets, the EBRD report concludes that it is advantageous to link FGD projects with byproduct fertilizer. A number
V. Evaluate the impact of continued use of FGDgypsumderived ammonium sulfate on soil chemical properties. VI. Establish a process flow sheet for the production of ammonium sulfate from FGD gypsum and evaluate the production costs and the market potential for the product. This project is a cooperative effort among the ISGS, UIUC, AUiedSignal, SEME,
Efficient ammonia desulfurization (EADS) technology is the core technology of JET. From the reaction between NH 3 and SO 2, the process is capable of efficiently removing SO 2 from the exhaust gas and also producing valuable fertilizer, ammonium sulfate. Compared to the most widely used limestonegypsum process in boiler flue gas treatment, the EADS process is more efficient, consumes less ...
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 highvalue ammonium sulfate (AS) fertilizer.
The goal of this study is to assess the technical and economic feasibility of producing marketable products, namely fertilizergrade ammonium sulfate and calcium carbonate, from gypsum produced as part of lime/limestone flue gas desulfurization (FGD) processes. Millions of tons of FGDgypsum by ...
