| titleOfInvention | Method for removing nitrogen oxides from a gas stream |
| abstract | A gas stream containing nitrogen oxides, such as the tail gas from a nitric acid plant, is treated to reduce the nitrogen oxides content thereof. The method results in the production of an aqueous solution of ammonium nitrate. In a liquid-gas contact apparatus, the gas stream is first reacted, under steady state conditions, in counter-current flow, with an aqueous solution of ammonium nitrate at a pH of about 0.01 to about 0.5. The gas stream is then further reacted with an aqueous solution of ammonium nitrate at a pH of about 8.1 to about 8.5; and thereafter with water, preferably slightly acidified to a pH of 6.0 to 6.5. The resulting gas stream of reduced nitrogen oxides content may be safely discharged to the atmosphere without causing air pollution, the nitrogen oxides content being below imposed standards. |
