New Technology Tackles Most Pollutants Emitted by Coal-fired Power Plants
Tests conducted at three coal-fired power plants show that a new technology can reduce mercury emissions at higher rates and lower costs than current methods, according to its developers, Chem-Mod LLC. But its ability to simultaneously remove the other pollutants associated with burning coal is what really sets the technology apart. The technology removed up to 98%, 90%, and 86% of the mercury in week-long tests with different bituminous and subbituminous grades of coals. In addition, the system cut SO2 emissions by 40–75% and those of arsenic, chloride, and heavy metals by 75–90%, estimates Douglas Comrie, vice president of Chem-Mod and the technology’s principal inventor.
