The scrubbing process is widely used to free flue gas from sulfur dioxide, and FGD gypsum is a by-product that originated in due process [6]. 'Wet-type scrubbing' and 'dry or semi-dry scrubbing' methods are generally employed for desulfurizing flue gas. However, wet-type scrubbing is extensively utilized in the majority of power plants [7].
Introduction. In an attempt to control SO 2 emission, various flue gas desulfurization processes are adopted in the coal-fired power plants, and the limestone-gypsum wet flue gas desulfurization (WFGD) is one of the most widely used technology due to a high SO 2 removal efficiency, whereas the problem of fine particle emission is …
Goal is to assess technical and economic feasibility for producing fertilizer-grade ammonium sulfate from gypsum produced in limestone flue gas desulfurization (FGD). 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., …
Since the 1990s, captured sulfur from flue gas has resulted in the production of high-quality gypsum, hydrated calcium sulfate: CaSO 4-2H 2 O. That synthetic gypsum can then be beneficially used ...
Flue gas desulfurized gypsum mainly comes from thermal power plants, smelters, and large-enterprise boilers, and contains industrial by-products produced through a wet desulfurization combustion process, where SO 2 gas and lime slurry react under strong oxidation conditions. The main component of this gypsum is calcium sulfate …
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.
