Produced from high quality natural ores at 8 facilities in North America, Carmeuse’s milled limestone products are used in a variety of industrial applications offering affordable and versatile solutions including flue gas desulfruization.
Chemical-grade milled limestone is slurried and sprayed in effluent stacks to de-sulfurize gas emissions from coal-fired electric power plants. Limestone reacts with SOx to form calcium sulfate (synthetic gypsum).
Limestone Forced Oxidation (LSFO) FGT units utilize limestone that is either milled on site to a 90% passing 325 mesh size (44 micron) or purchased already milled by the limestone supplier and ready to be slurried.
