Simultaneous removal of SO2 and NOx with ammonia combined with gas-phase oxidation of NO using ozone
A process for simultaneous desulfurization and denitrification was proposed, which was made up of ozone as the oxidizing agent for NO and ammonia solution as absorbent. The results showed that the presence of SO2 and the concentration changes of NO and SO2 have little impact on the oxidatio...

| description | A process for simultaneous desulfurization and denitrification was proposed,
which was made up of ozone as the oxidizing agent for NO and ammonia
solution as absorbent. The results showed that the presence of SO2 and the
concentration changes of NO and SO2 have little impact on the oxidation of
NO, the oxidation efficiency of NO can achieve over 90% when the molar ratio
of O3/NO is 1.0. The presence of NOx had little effects on the absorption of
SO2, an appropriate increase of SO2 concentration was favorable to the NOx
absorption. The removal efficiency of SO2 and NOx reached 99.34% and 90.01%
at pH 10, flow rate 0.95 Nm3/h, n[O3]/n[NO] 1.0, initial SO2 concentration
2000 mg/Nm3, initial NO concentration 200 mg/Nm3, ammonia concentration
0.3%, oxygen content of the simulated flue gas 12%, oxidation reaction
temperature 423K and absorption reaction temperature 298K in the
experimental system. |
