2. Research and development status of flue gas desulfurization and denitrification 2.1. Development status of flue gas desulfurization Sulfur dioxide gas is one of the main factors leading to the formation of acid rain. SO 2 reacts with water vapor in the air to form H 2 SO 3, which is oxidized to H 2 SO 4 by O 2 in the air. Acid rain

Flue gas desulfurization (FGD) is the treatment used to eliminate sulfur dioxide; it produces FDG gypsum as a by-product [8]. FGD gypsum takes up a lot of space in landfills and may contaminate the surface and groundwater [8]. The main ingredient of FGD gypsum is the same as in natural gypsum [10,11], so it can be used as a substitute for
