Analysis of FGD gypsum performed by various authors (Table 6) shows that FGD gypsum contains 36.9 – 54.4 % of SO 3, 28.1 – 46.7 % of CaO, and 0.01 – 3.81 % of MgO …
What is desulfurization gypsum. Desulfurization gypsum, also known as FGD gypsum (flue gas desulfurization gypsum), is an industrial by-product gypsum obtained by desulfurization and purification of flue gas generated after combustion of sulfur-containing fuel (coal, oil, etc.), and its composition is calcium sulfate dihydrate (CaSO 4.2H 2 O).. How desulfurization …
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 of ...
