stone slurry FGD systems. Chemistry for this particu-lar process involve a lime or limestone slurry which consists of a solution of calcium compound solids in suspension as well as calcium salts (sulfites and sul-fates) in solution. These dissolved compounds are generally not a significant problem unless the solution is saturated.

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.
