Characterization and Removal Potential of Fluorine in Lignite from a Mine in Shaanxi Province, China: A Case Study

“…[22] Various engineering measures, such as denitrification and desulfurization, can significantly reduce the amount of fluorine released during coal combustion, thereby reducing the associated environmental impacts [20]. The defluorination processes can be classified into defluorination before combustion, fluorine fixation during combustion, and flue gas defluorination after combustion [23,24]. The fluorine removal process depends on whether fluorine has an inorganic form, which is predominantly abundant, or organic form [9,20,25].…”
