Flue gas desulfurization (FGD) technologies can be used to remove SO 2 from flue gas. FGD technologies can be divided into wet, semi-dry, and dry systems. Wet limestone FGD systems, which use water to enhance performance, are the most common and achieve the highest SO 2 removal. Semi-dry FGD, which uses spray drying, is applied when low-to medium-sulfur fuels are being burned.

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.
