Gypsum Byproduct Processing Solutions
Download the gypsum processing flow sheets. Gypsum Processing Solutions. Gypsum Dewatering. Wet flue-gas desulfurization (FGD) systems generally operate in a pH of 5.0 or above and require feed of reagent to remove sulfur. Limestone slurry is the most commonly used reagent. The quantity of slurry depends mostly on the sulfur levels in the coal.
Processing Gypsum Drywall for Recycling
The two major objectives of processing are separation of gypsum from the paper and the size reduction of the gypsum itself. A big issue associated with drywall processing is dust, and this is addressed by containing as much of the processing system as possible (placing indoors) or by providing water in the form of a mist to minimize emissions. ...

Preparation of α-calcium sulfate hemihydrate from …
gypsum, flue gas desulfurization (FGD) gypsum and phosphogypsum (PG) have the largest output. FGD gypsum originates from the flue gas desulfurization installations by sorption of SO 2 in power stations. For example, in the wet-lime desulfurization method, the sorption reaction occurs via the reaction formulas (1, 2) (Roszczynialski et al., 1996a).
Understanding gypsum in 3 diagrams
According to Lavoisier and Le Chatelier, 9 the reaction is a process of dissolving hemihydrate to create a super saturated solution of gypsum, from which gypsum is formed. This is possible due to the lower solubility of gypsum compared to hemihydrate. This theory is proven by Figure 4a - 4i and it shows why gypsum can act …
