Abstract
In a process for the removal of ammonia, and, if required, dust, from waste gases which arise in the production of fertilizers, the waste gases are treated in an absorption zone with a circulated ammonium nitrate solution. The ammonium nitrate solution has a temperature theta of 20 to 100 DEG C and, at the entry to the absorption zone, a pH of at least a value given by the following formula <IMAGE> in which Y denotes the ammonia concentration of the gas to be treated in mg/m<3)<S.T.P.).
