Abstract: front page image
(EN)A method for production of ammonium phosphates comprises providing (210) of a phosphorus-loaded water immiscible liquid phase, adding (212) of anhydrous ammonia to the water immiscible liquid phase, precipitating (214) of mono-ammonium phosphate and/or di-ammonium phosphate from the water immiscible liquid phase and extracting (218) of the precipitated mono-ammonium phosphate and/or di-ammonium phosphate from the water immiscible liquid phase. The method further comprises controlling (216) of a temperature of the water immiscible liquid phase during the adding (212) and precipitating (214) to a predetermined temperature interval.
(FR)L'invention porte sur un procédé de production de phosphates d'ammonium comprenant l'obtention (210) d'une phase liquide non miscible avec l'eau chargée en phosphore, l'ajout (212) d'ammoniac anhydre à la phase liquide non miscible avec l'eau, la précipitation (214) de dihydrogénophosphate d'ammonium et/ou d'hydrogénophosphate d'ammonium dans la phase liquide non miscible avec l'eau et l'extraction (218) du dihydrogénophosphate d'ammonium précipité et/ou de l'hydrogénophosphate d'ammonium précipité de la phase liquide non miscible avec l'eau. Le procédé comprend en outre la régulation (216) d'une température de la phase liquide non miscible avec l'eau pendant l'ajout (212) et la précipitation (214) sur un intervalle de températures prédéfini.
