Sulfur Dioxide And Coal - vivinapoli REMOVAL OF ORGANIC SULFUR FROM COAL: THE USE OF LIQUID SULFUR DIOXIDE Duane F. Burow and Boris M. Glavincevski Department of ... Silica . Sulfur dioxide and coal - SourceWatch Coal-fired power plants are the largest human-caused source of sulfur dioxide, a pollutant gas that contributes to the production of acid rain and causes significant health problems, particularly through its role in forming particulates. Coal naturally contains sulfur, and when coal is burned, the sulfur combines with oxygen to form sulfur oxides. New technology removes sulfur from coal - . Luttrell adds, "If we can remove the sulfur, we can increase the value of eastern U.S. coals." Studies at the Center for Coal and Minerals Processing showed that the patented technology can increase the retail value of coal by $2-3 per ton by virtue of the lower sulfur content in the coal. 3.1 Coal sulfur reactions and impacts in oxy . 3.1.1 Sulfur species. Sulfur in coal is released during combustion forming species in the ash and flue gas which have a range of impacts and control options [5, 6]. SO 2 is the dominant species, with some SO 2, H 2 S and COS formed in locally reducing gas conditions of furnace gases.    Read More
