PROCESS FOR NO RECOVERY FROM OFF-GAS GENERATED IN THE PRODUCTION OF AMMON NITRITE |
| 摘要 |
<p>NO is completely recovered from the waste gas of ammonium nitrite production by absorbing the nitrous fumes in a first stage in an ammonium carbonate and/or ammonium bicarbonate solution to form ammonium nitrite solutions, absorbing the resulting waste gas containing carbon dioxide in a second stage in an ammonia solution to form ammonium carbonate and/or ammonium bicarbonate which is/are recycled as such into the first absorption stage.</p> |
