Abstract The article discusses coal cleaning options for reducing SO2 emissions. Conventional PCC can reduce the potential SO2 emission from high sulfur coal by 20-50%, depending on the inherent properties of individual coals. SO2 emission reduction by conventional PCC is limited by the amount of finely distributed mineral sulfur (pyrite) and organic sulfur in coal. Advanced fine coal cleaning technologies can be used to remove fine pyrite and sometimes organic sulfur. Coal cleaning may be used in combination with other technologies to reduce SO2 emission. Combinations such as coal cleaning and limestone injection multistage burners (LIMB) or flue gas desulfurization (FGD) may be more cost effective than FGD alone. The use of a multi-stream coal preparation plant to produce deep-cleaned and middling products is another control option. The deep-cleaned coal, which is low in ash and sulfur, can be burned without further SO2 emission control while the middling product can be burned in a boiler with a LIMB or FGD system.
