A formulation additive for simultaneously improving flue gas desulfurization efficiency and gypsum quality

The effects of different additives, including MgSO4, MnSO4, adipic acid, citric acid, benzoic acid, succinic acid and acrylic acid on SO2 removal from a limestone-gypsum wet flue gas desulfurization (FGD) system and gypsum characteristics were investigated. An optimized formulation additive for simu...
