Flue-gas desulfurization - The Full Wiki

A new, emerging flue gas desulfurization technology has been described by the IAEA. [6] 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.
