Abstract

PROCEDIMIENTO PARA LA OBTENCION DE UN TRIPOLIFOSFATO DE SODIO CON VELOCIDAD ELEVADA DE HIDRATACION.COMPRENDE LAS SIGUIENTES OPERACIONES: PRIMERA, SE PREPARA UNA SOLUCION DE ORTOFOSFATOS DE SODIO, MONOSODICO Y DISODICO, DE RELACION MOLAR GLOBAL DE SODIO A FOSFORO COMPRENDIDA ENTRE 1,64 Y 1,70; SEGUNDA, SE FORMA UNA CIRCULACION DE POZO-TORBELLINO CON UNA FASE GASEOSA CALIENTE CON GRAN CANTIDAD DE MOVIMIENTO; TERCERA, SE INTRODUCE LA SOLUCION DE ORTOFOSFATOS PREPARADA, EN LA ZONA DE DEPRESION DE LA CIRCULACION DE POZO-TORBELLINO, DE MANERA TAL QUESE PROVOCA LA DISPERSION Y EL TRATAMIENTO TERMICO DE DICHA SOLUCION DE ORTOFOSFATOS POR LA FASE GASEOSA, DE MANERA TAL QUE SE OBTIENE EL TRIPOLIFOSFATO; Y POR ULTIMO, SE SOMETE EL PRODUCTO OBTENIDO A UN TRATAMIENTO TERMICO COMPLEMENTARIO.
