| Dec 30, 2019 at 6:48 | comment | added | user5151477 | I need to purify the gas stream to zero ppb of SO2/NO/NOX. The gas is pre-treated by purafil and activated carbon. The flow rate is around 5 lpm. @DrMoishe Pippik | |
| Dec 30, 2019 at 6:46 | comment | added | user5151477 | As I mentioned, I need the gas stream free of NO and NO2 simultaneously. So, converting NO to NO2 is not the answer. Thanks. @Maurice | |

| Dec 24, 2019 at 10:24 | comment | added | Maurice | You may have the gas mixture bubble in a NaOH solution, or wash it through a column with flowing NaOH solution at countercurrent. SO2 and NO2 will be dissolved. And if some O2 is also present, NO will soon be oxidized into NO2, and then dissolved. | |
