Historically, sulfur dioxide (SO 2) emission limits have not been imposed on aluminum smelters, however increasingly stringent air emission standards are resulting in renewed interest in SO 2 emission reduction. SO 2 emissions in the aluminum smelting industry are primarily a product of the sulfur contained in the anodes.
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).

Dec 14, 2010· Sulfur dioxide (SO2) is one of a group of highly reactive gasses known as "oxides of sulfur." The Clean Air Act requires the EPA to set National Ambient Air Quality Standards (NAAQS) for criteria pollutants, including sulfur dioxide. The largest sources of SO2 emissions nationally are fossil fuel combustion at power plants (73 percent) and ...
The raw coke gas stripped of much of the sulfur content is normally burned as fuel for heating in the Clairton batteries, as well as the other U.S. Steel Mon Valley plants. Upon combustion, the remaining hydrogen sulfide component of raw coke gas largely converts to sulfur dioxide (SO2).
WHO Air quality guidelines Role of the guidelines in protecting public health The WHO measures (e.g. changes in lung function, inflammaair quality guidelines (AQGs) are intended for worldwide use but have been devel-oped to support actions to achieve air quality that
The Clean Air Act of 1990 initiated a tradable permit program for emissions of sulfur dioxide from coal-fired power plants. One effect of this policy was a large increase in the consumption of low-sulfur bituminous coal by coal-fired power plants. However, low-sulfur bituminous coal is also the ideal coking coal for steel production.
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 emission of sulphur dioxide for each coking plant was cal- culated from the volume of underfeed gases consumed and their- content of sulphur dioxide 0 In 1956., the total emission of sulphur dioxide by the mine coking plants amounted to £3,000 tons.
