Abstract

PARA LA FABRICACION DE POLIFOSFATO DE AMONIO ESENCIALMENTE INSOLUBLE EN AGUA CON FORMA LINEAL A PARTIR DE CANTIDADES EQUIMOLARES DE FOSFATO DE DIAMONIO Y DE PENTOXIDO DE FOSFORO EN PRESENCIA DE AMONIACO CON TEMPERATURAS DE 170 A 350 C POR MEDIO DE UNA MEZCLA, AMASADO Y TRITURADO CONTINUOS SE SUSTITUYEN EL FOSFATO DE DIAMONIO Y EL PENTOXIDO DE FOSFORO, AL MENOS PARCIALMENTE, POR ACIDO POLIFOSFORICO AMONIZADO PARCIALMENTE. UNA INSTALACION PARA LA REALIZACION DE ESTE PROCEDIMIENTO PUEDE ESTAR FORMADA POR UN REACTOR (1) CERRADO PROVISTO DE DISPOSITIVOS (2, 3) DE DOSIFICACION Y DE TUBOS (4, 5) DE ENTRADA DE PENTOXIDO DE FOSFORO Y DE ORTOFOSFATO DE DIAMONIO, DE UN TUBO (8) DE ENTRADA DE AMONIACO, DE UN TUBO (9) DE SALIDA DE POLIFOSFATO DE AMONIO ASI COMO DE UNA TUBERIA PARA LOS GASES DE ESCAPE. EN EL INTERIOR DEL REACTOR (1) SE DISPONEN UTILES GIRATORIOS DE MEZCLA, DE AMASADO Y DE TRITURADO. ADEMAS, SE PREVE UNA CUBA (11) CON AGITADOR Y CON CALEFACCION, QUE SE PUEDE LLENAR A TRAVES DE UNA TUBERIA(13) CON ACIDO POLIFOSFORICO, EN LA QUE SE PUEDEN ELIMINAR EL VAPOR DE AGUA Y EL AMONIACO DE LOS GASES DE ESCAPE PROCEDENTES DEL REACTOR (1) A TRAVES DE LA TUBERIA (20) Y DESDE LA QUE SE PUEDE LLEVAR AL REACTOR (1), A TRAVES DE LA TUBERIA (17) ACIDO POLIFOSFORICO PARCIALMENTE AMONIZADO.
