Abstract

Procédé de production de produits contenant du nitrate (engrais, produits techniques) à partir de masses fondues en surfusion, selon lequel une solution d'eau et de XN est évaporée jusqu'à ce que la teneur en XN soit de 50 à 99,8 % en poids, X représentant un ou plusieurs produits choisis parmi Ca, Mg, NH4, Na et K, et N représentant nitrate. La plage préférée de teneur en XN est de 70 à 99,5 % en poids. La masse fondue est refroidie et maintenue à une température égale ou inférieure au point de cristallisation et de la poudre de XN solide à fines particules constituée des phases d'équilibre est ajoutée à la masse fondue. Des gouttes de masse fondue sont ensuite formées, puis amenées à refroidir et à se solidifier pendant un laps de temps allant jusqu'à 70 secondes. Il est préférable d'utiliser une bande de refroidissement pour la solidification des particules. Ladite bande est refroidie par air, par eau ou par un autre milieuProcess for the production of nitrate-containing products (fertilizers, technical products) from supercooled melts, according to which a solution of water and XN is evaporated until the XN content is from 50 to 99.8 % by weight, X representing one or more products chosen from Ca, Mg, NH4, Na and K, and N representing nitrate. The preferred range of XN content is 70 to 99.5% by weight. The melt is cooled and maintained at a temperature at or below the crystallization point and solid fine particle XN powder consisting of the equilibrium phases is added to the melt. Melt drops are then formed, then allowed to cool and solidify for up to 70 seconds. It is best to use a cooling strip for solidification of the particles. Said strip is cooled by air, water or other medium
