Fossil-fueled power plants utilize different air pollution control machines, commonly referred to as flue gas desulfurization units or scrubbers, to decrease sulfur dioxide emissions (sulfur dioxide from power plants is the leading cause of acid rain).Gypsum Products SpringerLink
Desulfurization gypsum is an industrial by-product, with gypsum dihydrate (CaSO 4 2H 2 O) as a main component, produced by the use of limestone-gypsum wet desulfurization of coal-fired flue gas. During wet desulfurization, 1 t of SO 2 produces about 2.7 t of desulfurization gypsum [5], causing annual emissions of desulfurization gypsum The seawater desulfurization process includes the following three steps. (1) Absorption: the seawater contacts and absorbs the flue gas in the packed tower, and the pH of the seawater after absorption is 2–3. (2) Oxidation: dilute with fresh sea water and introduce aeration to oxidize sulfite.Summary of research progress on industrial flue gas desulfurization

With more than 12,000 agitators sold worldwide to over 1,500 FGD plants, EKATO is the No.1 agitator supplier in this market. For a detailed reference list worldwide or for a specific region please contact us.Desulfurization gypsum is an industrial by-product formed by desulfurization of flue gas generated by power plants, petrochemical plants, steel plants and other industries [1]. China is the world's largest coal producer and consumer [2]. The large consumption of coal leads to huge stockpiles of desulfurization gypsum [3].Calcium sulfate whisker prepared by flue gas desulfurization gypsum
Peanut (Arachis hypogaea L.) requires calcium (Ca) and phosphorus (P). Flue gas desulfurization gypsum (FGDG) and broiler litter ash (BLA) could be used as Ca and P fertilizer for peanuts. A pot study was conducted to determine the effects of BLA and FGDG on peanut yield and nutrient uptake compared to superphosphate (SP). Peanut Abstract The application of flue gas desulfurization (FGD) gypsum to ameliorate saline-alkaline soils not only provides a new use for FGD gypsum, but also provides a new method for improving saline Prospects of using flue gas desulfurization
The semi-dry flue gas desulfurization ash (SFGDA) is an industrial waste generated by the semi-dry desulfurization process, and its resources have been continuously attracted attention. Through the method of heat decomposition, the SFGDA decomposed into CaO and SO2 has emerged as a prominent research topic. This paper Purpose Soil salinization is a major obstacle to the development and utilization of land resources in coastal areas. The purpose of the study is to explore the desalting effect of flue gas desulfurization gypsum (FGDG) on coastal saline-sodic soils by evaluating changes of soil chemical properties (soluble ions, exchangeable cations, and Desalting effect of flue gas desulfurization gypsum (FGDG
At present, the continuous accumulation of the flue gas desulfurization (FGD) gypsum in steel plants leads to the serious environmental issues and resource waste. To achieve green and sustainable development for the steel industry, it is significant to improve the usage of by-product gypsum. Employing the sintering FGD gypsum, ferric The major bottleneck in SO 2 desulfurization from flue gas is the constituents of the flue gas itself. A typical flue gas from coal-firing plant with medium to high sulfur content has 75–80 vol% N 2,12–15 vol% CO 2,1800 ppm SO 2,500 ppm NOx, 5–7 vol% H 2 O, 3–4 vol% O 2,< 100 ppm CO, and 10–20 mg Nm −3 of particulates andSulfur dioxide removal: An overview of regenerative flue gas
Flue gas desulfurization (FGD) is the treatment used to eliminate sulfur dioxide; it produces FDG gypsum as a by-product [8]. FGD gypsum takes up a lot of space in landfills and may contaminate the surface and groundwater [8]. The main ingredient of FGD gypsum is the same as in natural gypsum [10,11], so it can be used as a substitute forWet flue gas desulfurization (WFGD) simultaneously removes Hg and SO2 from coal-fired power plant flue gas streams. Hg0 re-emission occurs when the dissolved Hg(II) is converted to a volatile form(PDF) Basic characteristics and comprehensive utilization of FGD gypsum
Flue gas desulfurization (FGD) gypsum is a waste material produced in desulfurization of flue gases in power stations and heating plants in high amounts. However, the industrial use of FGD gypsum is insufficient considering the amount of its production. Nowadays, it is mostly used for the production of gypsum plasterboards only, and the Crystals 2020, 10, 709 3 of 13 2.2.
