Coal pollution mitigation - Wikipedia

Coal pollution mitigation, sometimes called clean coal, is a series of systems and technologies that seek to mitigate the health and environmental impact of coal; in particular air pollution from coal-fired power stations, and from coal burnt by heavy industry.. The primary focus is on sulfur dioxide (SO 2) and nitrogen oxides (NO x), the most important gases which caused acid rain; and ...

How Coal Works Union of Concerned Scientists

Dec 15, 2017  If coal is high in sulfur or other impurities, it is washed with a water or chemical bath, removing up to 40 percent of inorganic sulfur in the coal. Not all coal is prepared using the same process. High-sulfur coal commonly undergoes washing to meet environmental regulations, while low-sulfur coal is often crushed and resized without being washed.
