10 Some Methods of Reducing Sulfur Oxides from Power ...

In the meantime some of the available low sulfur coal is being used at utility plants which would be able to meet the national emission standards using coals with a higher sulfur content than they are now using. In January 1974, the Bureau of Mines 2 estimated a shortage of low sulfur coal of 243 million tons in 1975 and 275 million tons in 1980.
