A literature review and bench-scale experiments were conducted to obtain process engineering data. Conversion of FGD-gypsum to ammonium sulfate was tested at temperatures between 60 to 70°C for a duration of four to six hours. A preliminary process flow diagram was proposed, and the economics of the process was estimated.

Normally, calcium sulphate dihydrate (CaSO 4 •2H 2 O) is used as a raw material and a subhydrate such as hemihydrate (CaSO 4 •0.5H 2 O) or anhydrite (CaSO 4) is produced. The subhydrate is the binding material, which reacts with water back to form gypsum. There are three main diagrams that can help us understand this cycle in detail.
Titanium Dioxide - Sulfate Process 2 Gypsum Production - Sulfate Process Titanogypsum (CaSO 4) production can be a unique by-product of the sulfate process.
