The present invention relates to a method for the continuous recovery of ammoniacal nitrogen from a gas stream directly produced by thermal hydrolysis or hydrothermal carbonization of nitrogen-containing wastes. The present invention also relates to a plant operating according to said method. The method and plant according to the present invention allow to recover, by means of temperature and pressure control, ammoniacal nitrogen in the form of an ammonium salt, preferably in the form of a solution of an ammonium salt or in the form of a crystalline ammonium salt.

Abstract
The present invention relates to a method for the continuous recovery of ammoniacal nitrogen from a gas stream directly produced by thermal hydrolysis or hydrothermal carbonization of nitrogen-containing wastes. The present invention also relates to a plant operating according to said method. The method and plant according to the present invention allow to recover, by means of temperature and pressure control, ammoniacal nitrogen in the form of an ammonium salt, preferably in the form of a solution of an ammonium salt or in the form of a crystalline ammonium salt.File in questo prodotto:
