| titleOfInvention | Nitric acid reconstitution |
| abstract | There is described a process for the reconstitution of NOX gases produced by the thermal decomposition of metal nitrates to nitric acid comprising the steps of: 1. contacting the NOX gases in counter-current relationship in one or more packed columns with cooled 50 to 60 percent nitric acid to remove as nitric acid a major portion of the originally introduced NOX values and provide an acid solution leaving the column having a temperature below about 180 DEG F. to remove as nitric acid a major portion of the originally introduced NOX values; 2. compressing the residual gases from step 1 to from about 2 to about 6 atmospheres absolute; 3. contacting the compressed gases from step 2 with from about 50 to about 60 percent nitric acid in a packed absorption column in counter-current relationship to remove substantially all of the remaining NOX values from the gas stream as HNO3; and 4. recovering 50-60% nitric acid as it accumulates. |
