The effective and safe use of FGD gypsum in agricultural land is still debated in some countries even though its effectiveness in soil management has been reported in many studies. Thus, the changes in the levels of soil salinity, alkalinity, crop yield, and other physicochemical properties in different soil types and crops after …

The potential use of flue gas desulfurization fly ash (FA-FGD) as a supplementary cementitious material (SCM) in concrete was analyzed in terms of performance in mortar samples and compared with those obtained with electrostatic precipitator desulfurization fly ash (FA-EPD) with the addition of gypsum (CaSO 4 ·2H …

Flue gas desulfurization (FGD) systems using lime or limestone as the chemical reagent are widely used throughout the world for SO 2 emissions control at coal-fired power plants. Ammonia-based ...

Flue gas desulfurization (FGD) gypsum removes 93.31% of fluoride from 109 mg/L to 7.3 mg/L. Fluoride can be efficiently removed at the optimum pH range of 5–11. Kinetics analysis indicates that the theoretical fluoride capacity at 1 g/L FGD gypsum is 96.9 mg/g. Equilibrium speciation analysis indicates that the decrease of system pH to …

A dynamic model representing an industrial flue gas desulfurization (FGD) unit has been developed. The purpose of this model is to anticipate new SO 2 emission legislation and to study some industrial issues such as the influence of a NH 3 slip (from the selective catalytic reduction (SCR) unit) or fly ashes (from the electrostatic precipitator).

Introduction. In the industrial production of China, the processing of phosphate rock, volcanic eruptions, kerosene combustion and aluminum smelting will lead to flue gas emissions containing a large amount of SO 2.SO 2 is a highly irritating gas. Because SO 2 is freely soluble in water and enters the respiratory tract, it can generate …

In this study we reviewed the Flue Gas Desulfurization processes and the different options to improve its efficiency as Non-regenerable Wet and Dry methods, the …

Abstract The treatment of flue-gas desulfurization (FGD) gypsum, a common solid waste material that is often affected by chloride ions, typically occupies large amounts of land, causes resource was...

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. …

Current study proposes an effective way to modify the properties of super-sulfated cement (SSC) paste and mortar with preheated flue gas desulfurization (FDG) gypsum at different temperatures and durations, and different sulfate compositions. Preheated FGDs with temperatures between 25 and 150 °C and durations between 0 …

Flue gas desulfurized gypsum (FGDG) is an industrial by-product discharged from thermal power plants, smelters, and large-scale enterprise boilers. It is produced when sulfur is removed from flues gases in the flue gas desulfurization (FDG) system, and the formation processes are shown by the following equations (Liu et al., …

This paper presents a comprehensive review of the state of the art in flue gas desulfurization (FGD) technologies for coal-fired boilers. ... gypsum produced from the MEL process may be lighter ...
