Summary of research progress on industrial flue gas desulfurization

Global statistics showed in 1998 that wet limestone desulfurization was the main technology used in flue gas desulfurization in power plants, accounting for 83% of flue gas desulfurization systems [89]. The limestone-gypsum wet desulfurization system mainly involves the absorption section and the oxidation section.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 Preparation of calcium ferrite by flue gas desulfurization gypsum

Flue Gas Desulfurization an overview ScienceDirect Topics

This reaction is of great interest in the study of wet flue gas desulfurization processes. In the case of the normally used absorption additive lime, the oxidation of S(IV) is an essential step in quantitatively producing the final product, gypsum (CaSO 4 2H 2 O). Beside detoxication of S(IV) the dewatering properties of gypsum are improved when a high oxidation yield is Abstract：The flue gas desulfurization method of large coal-fired power plants is gener ally limestone/gypsum wet method.But many equipments of this wet desulfurization syst em during daily operation often cause scaling problems.At present, more literature think s this scale is caused by the mixing of desulfurized gypsum and fly ash in VWHPRIODUJHFRDO ILUHGSRZHU IOPscience

Broiler Litter Ash and 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 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. FGD gypsum was taken from a steel plant located in Panzhihua, China.

Sulfur dioxide removal: An overview of regenerative flue gas

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 andIntroduction. 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 Production and resource utilization of flue gas desulfurized gypsum
