· Flue gas desulfurization (FGD) gypsum from the coalfired power plant is a combustion byproduct produced in high quantities. In China, more than 40 million tons of FGD gypsum had been produced by 2010 (Yu et al. 2014). In case of resource conservation and environment protection, it is highly important to investigate the recycling and ...
Alternatively, gypsum can be produced from FGD waste, which is a useful byproduct. Note that "mist eliminators" installed at the spray tower outlet or downstream ductwork collect slurry droplets and remove moisture from the flue gas. In some installations, the flue gas is reheated to avoid corrosion downstream in the power plant. Many scrubbers have gasbypassing capability, which can be used ...
This reaction is of great interest in the study of wet flue gas desulfurization processes. In the case of the normally used absorption additive lime, the oxidation of S(IV) is an essential step in quantitatively producing the final product, gypsum (CaSO 4 2H 2 O). Beside detoxiion of S(IV) the dewatering properties of gypsum are improved when a high oxidation yield is achieved.
