Abstract

La présente invention concerne un système (100) servant à la production de phosphates de mono- ou de di-ammonium complètement solubles, purs et bien définis, ledit système comprenant une section d'extraction (10), une section de lavage (20) et des systèmes de traitement final (90). La section d'extraction effectue une extraction liquide-liquide du phosphate entre un liquide de charge (1) comprenant de l'acide phosphorique et essentiellement exempt d'ions nitrate, et un solvant (5) ayant une solubilité inférieure à 2 % dans l'eau. La section de lavage effectue une extraction liquide-liquide du phosphate entre le solvant chargé en phosphate et une solution de lavage (4). Le solvant appauvri en phosphate est remis en circulation vers la section d'extraction afin d'extraire de nouveau le phosphate. La solution de lavage est une solution aqueuse de phosphate d'ammonium, au moins 80 % du phosphate d'ammonium étant du phosphate de monoammonium et/ou le solvant étant un alcool non miscible à l'eau. Les systèmes de traitement final comprennent une source d'ammoniac (60), un système d'addition (70), un système de refroidissement (50), un dispositif d'élimination de précipité (40) et un système de recirculation (80).
