SULPHUR PROFILE IN COAL – MSK

The primary forms of sulfur in coal are pyritic sulfur (FeS 2), sulfate sulfur (CaSO 4. 2H 2 O, FeSO 4. 7H 2 O) and organic sulfur (mercaptan, the others, disulfide and aromatic systems containing thiophene rings).Of the two predominant forms, pyrite and organic, the former is easier to remove by physical and chemical methods without altering the structure of coal. Organic sulfur, being a part ...

A particular coal contains 2.55% sulfur by mass.

A particular coal contains 2.55% sulfur by mass. When the coal is burned, it produces SO2 emissions, which combine with rainwater to produce sulfuric acid. Use the formula of sulfuric acid to calculate the mass percent of S in sulfuric acid. Then determine how much sulfuric acid (in metric tons) is produced by the combustion of 1.0 metric ton of this coal. (A metric ton is 1000 kg.) Answer the ...

CONTROL OF SULFUR OXIDES

Sulfur oxides are produced from the burning of fossil fuels, mainly coal and oil, and the smelting of metal ores that contain sulfur. Emissions of sulfur oxides cause serious impacts on human health and the environment, both directly and as a result of the way they react with other substances in the air. Sulfur oxides are main precursors of
