FGD Gypsum Production Process – Gypsum Association

FGD Gypsum Production Process. Mineralogically identical to natural gypsum, FGD gypsum, or synthetic gypsum, is produced from gas captured within emission control systems at coal fired electric utilities. An emission that would compromise air quality, sulfur dioxide (SO 2) gas, is the primary contribution coal makes to FGD gypsum.

Gypsum Products | SpringerLink

When gypsum is heated at about 150–160 °C, it loses approximately three-quarters of its water in a partial dehydration process and becomes hemihydrate gypsum (CaSO 4 •½H 2 O) or calcined gypsum; it is also known as beta gypsum (alpha gypsum is made by processing batches of gypsum under elevated pressure). Calcined gypsum or …

Effect of Ball Milling Time on the Performance of Phosphorous

Variation of the specific surface area of PBG. The specific surface area of phosphate gypsum gradually increases as the ball milling time increases, reaching a maximum value of 2813.65 (S/V) at the ball milling time of 50 min, which is a 55% increase compared with the value (1815.23 (S/V)) before the ball milling.
