STUDY ON AMMONIA-BASED SIMULTANEOUS DESUFURIZATION AND
DENITRIFICATION FOR SINTERING FLUE GAS
Abstract
Experimental researches of enhancing ammonia-based sintering flue gas simultaneous desulfurization and
denitrification were performed in bubbling reactor. Effects of molar ratio of additive to NO,NH3 - NH +
4 concentration in
absorbing liquid and properties of flue gas on sintering flue gas desulfurization and denitrification were studied. According to
the research results,with increasing molar ratio of additive to NO,flue gas temperature and NO concentration,NOx removal
efficiency increased at first,but then decreased with further increase of molar ratio of additive to NO,flue gas temperature and
NO concentration. NOx removal efficiency increased with increasing NH3 -NH +
4 concentration in absorbing liquid. Increasing
SO2 concentration decreased NOx removal efficiency. Under all experimental conditions,SO2 removal efficiency approached or
reached 100%. And under optimal conditions,NOx removal efficiency could reach 61. 49%. NOx removal efficiency of
ammonia-based sintering flue gas desulfurization process raised 20% ~ 30% by adding additive to partially oxidize sintering
flue gas.
