1. Introduction. Flue gas desulfurization (FGD) gypsum is a synthetic form of gypsum created as a by-product of carbon-based energy sources (typically coal combustion) (Chen and Dick, 2011; Chen et al., 2014).Limestone forced oxidation scrubbers remove sulfur dioxide from the flue gas stream of sulfur-heavy energy …

1.1. Flue gas desulfurization processes. The flue gas desulfurization (FGD) processes can be separated into two main categories: once-through and regenerable processes, depending on how the sorbent is treated after SO 2 adsorption (Srivastava and Jozewicz, 2001).Once-through, or non-regenerable, processes utilize the sorbent as a …
Synthetic Gypsum Gypsum Doesn't Have To Come From A Mine. It Can Be Made Too. The process of making American Gypsum's Synthetic Gypsum (FGD Gypsum) at our Georgetown, SC facility starts at our partner power plants, where SO2 gas (sulfur dioxide) is passed through limestone that is sprayed in the air pollution control scrubber stack.
Utilities that produce panel-grade synthetic gypsum beneficially reuse FGD sludge rather than landfilling the material. A multistage production process is necessary to transform the SO 2 in flue gas, into panel-grade …

In 2020, global FGD-gypsum production is expected to reach 255 million tons, with Asia accounting for 55%, followed by Europe (22%), North America (18%), and the rest of the world (5%).
manufacturers of wallboard and plaster products. Small quantities of high-purity gypsum, used in a wide range of industrial processes, accounted for the remaining tonnage. At the beginning of 2019, the production capacity of 63 operating gypsum panel manufacturing plants in the United States was about 34.1 billion square feet1 per year. Total
Despite a wealth of deposits, natural gypsum is a less important source of raw material in Chinese gypsum wallboard production than phosphogypsum and synthetic gypsum from flue gas desulphurisation (FGD) at coal-fired power plants. 6 Most reserves are not economically situated, nor of consistent purity, when compared with the …

gypsum board. The production of FGD gypsum reduces the emission of harmful materials into the atmo-sphere and thus reduces air pollution. Natural gypsum and FGD gypsum are calcium sulfate dihydrate (CaSO4·2H2O). The gypsum in natural and FGD gypsum is chemi-cally identical and both are naturally fire-resistant. FGD gypsum has been used …
