6.7 How does the sulfur get into the atmosphere? The burning of coal. Coal contains 1-3% sulfur and coal burning power plants usually burn about 1 million metric tons of coal a year! S( s ) + O 2 ( g ) SO 2 ( g ) 2 SO 2 ( g ) + O 2 ( g ) 2 SO 3 ( g ) Once in the air, the SO 2 can react with oxygen molecules to form sulfur trioxide, which acts in the formation of aerosols. Burning of sulfur with oxygen produces sulfur dioxide gas, which is poisonous. The Combustion of Coal In a single power plant, 1million metric tons of coal are burned per year. From this, we can calculate the amount of SO 2 released into our atmosphere This amount is staggering! 88 million pounds of SO 2 are released into the atmosphere every year – from a single plant! Some plants that burn higher sulfur coal can produce even more than this! The Combustion of Coal The burning of coal by power plants produces the lion’s share of all sulfur dioxide in the atmosphere The Combustion of Coal The world’s largest smelter is in Ontario, Canada This plant produces nickel and copper ores of nickel and copper sulfides The smelting process produces SO 2 from these ores Even after intensive re-design, this plant and it’s neighboring smelters still produce over 200,000 metric tons of sulfur dioxide every year Is this a bad thing? Check it out… Fig. 6.15 Sudsbury, Ontario Canada – Smelting Plant Wanna live here? The Combustion of Coal Vast quantities of sulfur dioxide released into the atmosphere by smelting and power plants are the primary contributors to acid rain from SO 2 emissions But we noted earlier that SO X

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
