| titleOfInvention | Production of ammonium nitrite |
| abstract | PURPOSE: To enhance NH 3 NO 2 yeild and reduce the NOx content of exhaust gas by adding auxiliary NOx gas contg. more eNO 2 to absorption tower outlet gas of each stage to regulate NOx in each mixed gas to a specific molar ratio of eNO/eNO 2 and contacting the gas to an ammonium carbonate soln. of a specific temp. n CONSTITUTION: Auxiliary NOx gas having the molar ratio of eNO/eNO 2 about 0.05W0.8 is added from each auxiliary gas feed line 4aW4c to residual NOx gas A passed through a gas-liquid contact zone, i.e. liquid cylindrical part 9 and packed bed part 10 in each absorption tower 2aW2d of multistage absorption tower 2 to regulate the molar ratio of eNO/eNO 2 in mixed gas B to about 0.9W5. Gas B is supplied to the next stage tower in succession and contacted to a circulating absorbing soln. of -10W10°C contg. ammonium carbonate mixed with an absorbing soln. of the upper stage in each tower 2aW2d. NOx gas is supplied to first tower 2a through line 1, and an ammonium carbonate soln. is supplied from fresh ammonium carbonate soln. supply line 7. n COPYRIGHT: (C)1979,JPO&Japio |
