  • Sulfer Oxides Control in Japan

    Growth in FGD capacity has begun to decline in Japan recently for several reasons. Ambient S02 concentrations in large cities and industrial districts dropped to the 0.02 ppm to 0.03 ppm range; this is close to achieving the ambient standard of 0.016 ppm. The recent downturn in the Japanese economy has affected FGD plant construction.

  • 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.
