new so2 process For determining the quality

sulfur dioxide (SO2) from the exhaust flue gases emitted by coal- or oil-burning power plants. The SO2 is created when the power plants burn coal or oil to produce steam to power the steam turbines that drive the electricity generators. The tall flue gas stacks of a power plant disperse the gas emissions by diluting the pollutants in ambient air.

    Jan 19, 2021 · Sulfur Dioxide (SO2) Primary Air Quality Standards. The Clean Air Act requires EPA to set national ambient air quality standards (NAAQS) for sulfur dioxide and five other pollutants considered harmful to public health and the environment (the other pollutants are ozone, particulate matter, nitrogen dioxide, carbon monoxide, and lead). The law also requires EPA to periodically review the standards to ensure that they provide adequate health and environmental protection, and to update those
