Abstract
La invención se refiere a un método para ajustar el tamaño de los cristales en una cristalización masiva continua, especialmente de sulfato de amonio. Según la invención, esto es posible gracias a la aplicación de un método que prevé el agregado de un material de siembra cuyos parámetros de obtención son independientes del proceso de cristalización propiamente dicho, siendo el diámetro promedio de los sólidos del material de siembra de 0,1 a 1,0 mm y menor que el del producto de cristalización deseado, obteniéndose los sólidos del material de siembra independientemente del proceso principal de cristalización a partir de diferentes corrientes parciales preparadas por separado y que tienen tamaños de partícula del rango indicado, siendo la temperatura del material de siembra, al ser agregado, hasta 40°C y preferentemente 10 a 30°C inferior a la temperatura de procesamiento dentro del catalizador, careciendo todas las demás alimentaciones y retornos al catalizador de sólidos. Gracias al ajuste de los parámetros del material de siembra es posible influir la granulometría del producto final y disminuir claramente las fluctuaciones de la granulometría del producto final. El método puede aplicarse tanto cuando el material de siembra se agrega discontinuamente como cuando se agrega de manera continua.
