Abstract

Procédé pour extraire l'ammoniac d'une liqueur ammoniacale faible en utilisant un composé de calcium. On mélange au préalable la liqueur ammoniacale avec un composé de calcium soluble pour précipiter d'abord les composés de calcium insolubles de liqueur non distillée, puis on fait passer la liqueur soumise à cette précipitation préalable dans un appareil de distillation d'ammoniac, à contre-courant avec un gaz chauffé, pour extraire l'ammoniac Application à l'extraction d'ammoniac d'une liqueur ammoniacale faible provenant d'une opération de cokéfaction de charbon.
