Abstract
Purification procedure of the waste gases from the preparation of ammonium nitrite, and reuse of these waste gases with a view to the preparation of ammonium carbonate by absorption of CO2, characterized in that the gases containing carbon dioxide are washed as well as small amounts of ammonium nitrite and ammonium denitrate with an aqueous ammonia solution and, simultaneously adding supplemental carbon dioxide, the reaction is conducted in such a way that the proportion of ammonia in the final gas is less than 0.1% by volume, obtaining the Instead, use ammonium carbonate solutions of a concentration of 15 to 20% by weight.
