  • Sulphur dioxide (SO2) emissions control - Platte River

    The SO2 emissions are controlled using a spray dryer absorber (SDA) flue gas desulfurization system. During the SDA process, hot flue gas with entrained coal flyash passes through large reaction chambers where a mixture of recycled flyash/SDA product slurry, and lime-water slurry (calcium hydroxide) is sprayed and atomized.

    Apr 02, 2019Control measures that reduce SO 2 can generally be expected to reduce people’s exposures to all gaseous SO x. This may have the important co-benefit of reducing the formation of particulate sulfur pollutants, such as fine sulfate particles. Emissions that lead to high concentrations of SO 2 generally also lead to the formation of other SO x.

    An SO 2 scrubber system is the informal name for flue gas desulfurization (FGD) technology, which removes, or "scrubs," SO 2 emissions from the exhaust of coal-fired power plants. A scrubber works by spraying a wet slurry of limestone into a large chamber where the calcium in the limestone reacts with the SO 2 in the flue gas.
