6.2.1. Acid Gas Removal (AGR) | netl.doe.gov

Inorganic sulphur, in the form of pyrite (FeS2), can be removed from coal relatively easily simply by washing the coal. This method can result in a reduction of 10 - 50% of total sulphur content.

Removal characteristics of sulfuric acid aerosols from ...

Power plant boiler houses designed to burn coal or high sulfur oil are required by Federal and State pollution regulations to "scrub" (remove) sulfur dioxide from flue gasses to meet emission limits. SO2 in flue gasses is known to be harmful to the environment, as it is one contributor to the formation of acid rain. pH control is critical for the proper functioning of the scrubber system ...
