According to a method of producing a phosphate fertilizer, a first portion of the phosphate is produced in a pipe cross reactor, and a second portion of the phosphate is produced in a pre-neutralizer. Both the first and second portions of the phosphate are supplied to a granulator. Ammonia is added to the granulator to react with the first and second portions of the phosphate. To produce the first portion of the phosphate, a micronutrient is added to phosphoric acid to produce an enriched acid, and the enriched acid and ammonia are added to the pipe cross reactor where they are allowed to react to produce ammonium phosphate.
Selon une méthode de fabrication d'engrais phosphaté, une première partie du phosphate est fabriquée dans un réacteur tubulaire à flux croisés, et une deuxième partie du phosphate est fabriquée dans un préneutralisant. Les deux parties du phosphate sont fournies à un broyeur. De l'ammoniaque est ajouté au broyeur pour réagir avec les deux parties du phosphate. Afin de fabriquer la première partie du phosphate, un oligo-élément est ajouté à de l'acide phosphorique pour produire un acide enrichi, et, ensuite l'acide enrichi et l'ammoniaque sont ajoutés au réacteur tubulaire à flux croisés où ils peuvent réagir afin de fabriquer du phosphate acide d'ammonium.
