FGD Gypsum Introduction

Introduction to FGD Gypsum. FGD Gypsum is a unique synthetic product derived from flue gas desulfurization (FGD) systems at electric power plants. Sulfur dioxide emission control systems used by coal-fired power plants remove sulfur from combustion gases using "scrubbers." One particular type of scrubber that uses lime or limestone reagent (i.e ...

The second most common use of CCPs is flue gas desulfurization (FGD) gypsum in wallboard. This material is produced by emissions control systems (scrubbers) that remove sulfur and oxides from power plant flue gas streams. Residues vary, but the most common uses in construction applications are FGD gypsum (or "synthetic" gypsum).
