Abstract
Procédé pour extraire l'ammoniac de solutions ammoniacales, qui sont traitées au lait de chaux dans une colonne d'extraction 2, 3 et desquelles l'ammoniac est entraîné par un gaz chaud, des vapeurs ou des vapeurs d'échappement, tandis que les boues contenant de la chaux, du sulfate de calcium, de l'hydroxyde non consommé, du carbonate de calcium et d'autres combinaisons de calcium sont soutirées de la partie inférieure de la colonne et amenées à un dispositif séparateur 13 dans lequel la boue se sépare du liquide. Ce procédé est caractérisé en ce que du dispositif séparateur 13 on extrait une boue susceptible d'être pompée et qu'on brûle celle-ci dans une chambre de combustion reductrice 18 avec addition de gaz de chauffage et d'air, à une température de 600 à 1200 degrés C. Application : traitement d'eaux ammoniacales.
