The high sulfur content of coal has been recognized as the source of air pollution problems (acid rain), particularly from electricity generation and in industrial boilers, and also a cause of other environmental problems such as acid mine drainage due to oxidation of pyritic sulfur in coals.
tons, or 86 percent, is high-sulfur coal (containing 1.681 pounds or more sulfur per million Btu). Wyoming surface mining is currently the Nation's leading source of inexpensive, low-sulfur coal. The Wyoming study was designed to reevaluate the fundamental coal quality allocations for the State's coal resources that are exploitable by surface mining.
The sulfur content of coals available to utilities ranges from about 4 percent in high-sulfur coals to less than 1 percent in some Western coals. Although transportation costs maybe higher for Western coals, many Eastern utilities elect to burn Western coals to comply with increasingly stringent SO, regulations.

Coking coal is cleaned so that the coke ash content is not over 10%. An upper limit of 1—2 wt % sulfur is recommended for blast furnace coke. A high sulfur content causes steel (qv) to be brittle and difficult to roU. Some coal seams have coking properties suitable for metallurgical coke, but the high sulfur prevents that appHcation.
Form 10 K Big Bend Coal High Sulfur Content Percentage. 2017-10-10The Big Bend coal units went into service from 1970 to 1985 and the CT was installed in 2009. The Polk IGCC unit began commercial operation in 1996. . 1 or 1 refers to sulfur content as a percentage in coal by weight. 3 . they can also be marketed as an ultra-high BTU low sulfur ...
According to the EIA, low sulphur content coal is defined as having less than 0.60 pounds of sulphur per million British thermal units (or MMBtu). Medium sulphur content coal has 0.61-1.67 pounds of sulphur per MMBtu, and high sulphur content coal has more than 1.67 pounds of sulphur per MMBtu.
In general, the sulfur content of the higher sulfur coals can be reduced more than those with lower sulfur content. At a 1 percent sulfur level in the raw coal sulfur content is reduced by about 0.2 percent while at a 3 percent sulfur level it is reduced to about 1.5 percent.
Extraction time effect on the recovery of organic sulphur compounds showed that the recovery of organic sulphur investigated was up to 88% with 75 minutes ultrasonic bath extraction. Another important effect of increase in ash content on the coal combustion is the change in the thermal and radiative properties of the coal and the gas inside the furnace. Sarofim et al.  found that the ...
The strong demand for low-sulfur coal threatened high-sulfur coal producers, primarily in the East (see Figure 1). In order to save coal-mining jobs in the East, the Clean Air Act was amended in 1977 to require equipment on all new coal-fired power plants to physically remove sulfur from the smokestacks after combustion, reducing the attractiveness of low-sulfur coal (all coal becoming ...
Bituminous coal deposits in the eastern coal field are lower in sulfur content, averaging between 1 and 2 percent by weight. Coal deposits from the western part of the state are slightly lower in heat content but higher in sulfur, averaging between 3 and 4 percent sulfur.
