Kinetics of gas–liquid reaction between NO and Co(NH3)62+

Integrative process of preoxidation and absorption for simultaneous removal of SO2, NO and Hg0

“…Therefore, the methods for simultaneous removal of SO 2 , NO and Hg 0 have been extensively researched in recent years. Many reagents such as Fe(II)-EDTA [10], Co(NH 3 ) 6 3+ [11], KMnO 4 [12], CO(NH 2 ) 2 [13], K 2 FeO 4 [14], NaClO 2 [15] and H 2 O 2 [16,17] etc., have been used to simultaneously remove SO 2 , NO and Hg 0 . Nevertheless, most of these cannot be developed for industrial use due to the technical and economic problems.…”

Experimental determination of equilibrium constant for the complexing reaction of nitric oxide with hexamminecobalt(II) in aqueous solution

“…Long [19][20][21][22][23][24][25] has proposed a novel technique for the simultaneous elimination of NO and SO 2 from the flue gases by adding soluble cobalt(II) salt into the aqueous ammonia solution. The hexamminecobalt(II) ion produced by NH 3 coordinating with Co 2+ can not only bind NO but also activate the oxygen molecule.…”

Experimental investigation of nitric oxide removal from flue gas using hexamminecobalt(II) solution scrubbing in a pilot-scale facility

“…When the inlet NO concentration was 600 ppm, the NO removal efficiency was 8.4% higher than those corresponding to 200 ppm and 400 ppm. The NO removal efficiency increased with the incoming NO concentration, which seems to make sense because greater NO partial pressure increases the mass transfer and chemical reaction speed of NO (Long et al, 2005b; Wang et al, 2016a).…”
