Flue gas desulfurization Wikipedia

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

Influence of flue gas desulfurization FGD installations

Additionally NH 4 was expected to be emitted into the atmosphere along with gypsum slurry entrainment since excessive NH 3 as a reducing agent slipped from the SCR is partly absorbed by the recirculation slurry in an FGD where ammonium NH 4 is formed from NH 3 and accumulates to relatively high concentrations
