A new, emerging flue gas desulfurization technology has been described by the IAEA. It is a radiation technology where an intense beam of electrons is fired into the flue gas at the same time as ammonia is added to the gas. The Chendu power plant in China started up such a flue gas desulfurization unit on a 100 MW scale in 1998.
The global flue gas desulfurization (FGD) systems market size was valued at $17,869.1 million in 2018, and is projected to reach $25,063.8 million in 2026, growing at a CAGR of 4.1%. Flue gas desulfurization systems are used to remove sulfur dioxide (SO2) contained in gases formed by the ignition of ...

They will have the capacity of 670 MW each, matching the power plant's two units.
Wet Lime FGD. The process of wet scrubbing typically utilizes an alkaline-based slurry of lime to scrub gases. A shower of lime slurry is then sprayed into a flue gas scrubber, where the SO2 is absorbed into the spray and becomes a wet calcium sulfite. One by-product of that sulfite is it can be converted to salable gypsum.
