2019年12月1日 · Flue gas desulfurization gypsum (FGDG) is an industrial by-product generated during the flue gas desulfurization process in coal-fired power plants. Due to its abundance, chemical and physical properties, FGDG has been used in several beneficial applications.

Flue-gas desulfurization (FGD) is a set of technologies used to remove sulfur dioxide (SO2) from exhaust flue gases of fossil-fuel power plants, and from the emissions of other sulfur oxide emitting processes such as waste incineration, petroleum refineries, cement and lime kilns.

2021年11月1日 · 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 …

2023年11月13日 · Thermal Power Plant generates FGD gypsum as by-product during coal combustion. This study evaluates the characterization (spectroscopic and elemental), potentially toxic elements (PTEs)...

Electric utilities produce more than 11.2 Mt of flue gas desulfurization (FGD) gypsum annually. Approximately 7.5 Mt is used in wallboard production. This article examines the environmental and cost benefits associated with replacement of natural gypsum in wallboard with FGD gypsum.

2023年8月22日 · Flue Gas Desulphurized Gypsum (FGDG) is a by-product generated by the thermal power industry to remove sulfur dioxide (SO 2) from flue gas emissions. This paper provides a comprehensive review of flue gas desulphurized (FGD) gypsum production, property, and applications in the construction industry.

2021年3月5日 · Employing the sintering FGD gypsum, ferric oxide, and graphite carbon as raw materials, the effects of the carbon content, reaction time, and molar ratio of CaO to Fe 2 O 3 on the desulfurization rate of gypsum were studied based on the orthogonal experiment.

Electric utilities produce more than 11.2 million Mg of flue gas desulfurization gypsum annually. Approximately 7.5 million Mg are used in wallboard production. This paper examines the environmental and cost benefits associated with replacement of natural gypsum in wallboard with flue gas desulfurization gypsum.

2016年4月4日 · A recent study has revealed that flue gas desulfurization (FGD) gypsum and lignite humic acid application enhanced the salt leaching and crop production. The purpose of this study was to investigate the effects of applied FGD gypsum and lignite humic acid (powder) on the soil organic matter (SOM) content and physical properties.

2014年1月1日 · F lue gas desulfurization gypsum (FGDG) is a synthetic gypsum that is created during the removal of SO 2 from flue gas by reacting the SO 2 with calcite (CaCO 3) to form calcium sulfite (CaSO 3· 0.5H 2 O), which is further treated with wet limestone and forced oxidization to form calcium sulfate (CaSO 4· 2H 2 O) (Laperche and Bigham, 2002).
