8.4.3 Emissions And Controls1 Ammonium sulfate particulate is the principal emission from ammonium sulfate manufacturing plants. The gaseous exhaust of the dryers contains nearly all the emitted ammonium sulfate.
Bench-scale experiments will be conducted to obtain process engineering data for manufacture of ammonium sulfate from FGD-gypsum and to help evaluate technical and economical feasibility of the process. Controlled greenhouse experiments will be conducted at UIUC to evaluate the chemical impact of the produced ammonium …
Semantic Scholar extracted view of "Reaction Kinetics of Production of Ammonium Sulfate from Anhydrite" by G. Cordell. ... The reactivity of flue gas desulphurization gypsum with ammonium carbonate has been studied in the temperature range (20–50) °C. ... This work addresses the optimum design of a phosphoric acid (PA) production process ...
Assessing the potential of using FGD gypsum as a source of sulfur fertilizer, it has been found that both FGD gypsum and ammonium sulfate provide sufficient amounts of sulfur for plants. The production of canola oil varies greatly depending on whether it receives sufficient sulfur, but the source of the sulfur is irrelevant.
The goal of this study is to assess the technical and economic feasibility of producing marketable products, namely fertilizer-grade ammonium sulfate and …

In the field of chemical industry, gypsum is commonly used as a raw material for the production of sulfuric acid, ammonium sulfate, calcium carbonate, and other chemicals containing sulfur or calcium.
Goal is to assess technical and economic feasibility for producing fertilizer-grade ammonium sulfate from gypsum produced in limestone flue gas desulfurization …
The present study aims to synthesize ammonium sulfate from low-grade naturally occurring gypsum found in Rajasthan, India. Ammonium sulfate was prepared by adding a fixed amount of natural gypsum with an appropriate quantity of ammonium carbonate in distilled water at varying temperatures for different contact times in a batch …
The objectives of this phase were to evaluate the chemical properties of ammonium sulfate made from this FGD-gypsum; to estimate its effect on soil productivity; to develop or modify the process in order to purify the gypsum; and to determine engineering parameters and a process flow diagram to aid in the design and construction of a pilot ...
The second system (b) is the most favored because of its availability, relative low cost, and ability to produce a marketable gypsum. The process is designed to produce a high-quality product (gypsum) suitable …

This is the 1st year of a 2-year program among Illinois State Geological Survey, University of Illinois (Urbana-Champaign), Allied-Signal, Marketing Chem. Process Inc., …
Ammono-carbonation reaction of any kind of gypsum (pure, PG or FGD gypsum) with ammonium carbonate known as Merseburg Process is used to produce ammonium sulfate and calcium carbonate.
Solid Ammonium Sulfate: By 2023, Solid Ammonium Sulfate had achieved over 90.0% market share. This form of Ammonium Sulfate is favoured due to its stability, ease of handling and versatility in various applications – often being utilized for agricultural fertilization as well as industrial processes for chemical production or other solid ...
FGD-gypsum from Abbott power plant was used. The scrubber, a Chiyoda Thoroughbred 121 FGD, produced a filter cake (98.36% gypsum and < 0.01% CaSO{sub 3}). Conversion of FGD- gypsum to ammonium sulfate was tested at 60-70{degree}C for 5-6 hr. Yield up to 82% and purity up to 95% were achieved for the ammonium sulfate …
