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.

Flue gas desulfurization Flue gas desulfurization is commonly known as FGD and is the technology used for removing sulfur dioxide (SO 2) from the exhaust combustion flue gases of power plants that burn coal oroil to produce steam for the turbines that drive their electricity generators.
JANUARY 12, 2018 Cleaning up with FGD Technology: Making Profitable Trade-offs in Desulfurizing Power Alex Forbes. Tightening environmental regulations around the world make flue gas desulfurization (FGD) technology a must for most existing and new coal-fired power stations, but choosing the right technology can be a challenge.
Limestone-gypsum flue gas desulfurization process is the world's most widely used FGD technology. About 90% of Japan, Germany, and the U.S. power plants use gypsum desulfurization process, which is wet scrubbing using a slurry of alkaline sorbent, usually limestone or lime. Joyal has been engaged in limestone grinding for more than 30 years.
