The synthesis of α-calcium sulfate hemihydrate (α-CSH) from flue gas desulfurization (FGD) gypsum is a good way to realize the comprehensive utilization of FGD gypsum.To obtain α-CSH with the satisfactory performances, a facile hydrothermal-aging pretreatment process for FGD gypsum raw materials was proposed, where FGD …
1. Introduction. Wet flue gas desulfurization (WFGD) systems are widely adopted in coal-fired power plants. Flue gas desulfurization (FGD) wastewater is regularly discharged by the desulfurization tower in the process of WFGD to control the chloride (Cl −) concentration in the desulfurization slurry.The accumulation of Cl − in WFGD system …

Guide for conducting FGDs with children – April 2019 5 to find a balance between the pressure for reliable evidence, operational needs, and constraints, and ethical issues such as the specific techniques and safeguards that must be considered when conducting FGDs with children. Before starting to organise and plan for FGDs, we should decide if Focus …
Flue gas desulfurization gypsum (FGDG) is an industrial by-product generated during the flue gas desulfurization process in coal-fired power plants. Due to …
FGD gypsum is a relatively new by-product from the power plant compared with fly ash due to the recent installation of FGD equipment in China. At the end of the 20th century, several researchers have engaged in development of new uses for FGD gypsum. They have identified a number of agricultural and engineering properties of these FGD …
The application of flue gas desulfurization (FGD) gypsum has been recognized as a feasible measure in enhancing the quality of sodic soils. Quantitative evaluation of the effects of FGD gypsum on three-dimension (3D) pore characteristics is beneficial for understanding the reclamation mechanism of FGD gypsum on sodic soils.
We measure the diffusion of FGD from 1970 to 2010 and consider the contributions of unit numbers, unit size, type of FGD (retrofit versus new build) and …
1. Introduction. Hypersaline wastewater generated from industries, including the coal chemical industry, petrochemical industry, pesticide, and flue gas desulfurization (FGD), is becoming an increasing concern for environmental issues [1].Improper disposal of hypersaline wastewater can result in severe environmental problems and threaten …
FGD-gypsum and cover crop effects on soil physical properties. Bulk density (ρb), as a measure of soil compaction, was significantly affected by FGD-gypsum and cover crop managements (Table 7). FGD-gypsum amendments marginally decreased ρb, while the cover crop significantly decreased the ρb by more than 4% compared to …

The use of waste incineration with energy recovery is a matured waste-to-energy (WtE) technology. Waste incineration can reduce the volume and mass of municipal solid waste significantly. However, the generation of high volumes of polluting flue gases is one of the major drawbacks of this technology. Acidic gases are constituents in the flue …
