Abstract

PARA LA FABRICACION DE POLIFOSFATO AMONICO EN FORMA DE CADENA, ESENCIALMENTE INSOLUBLE EN AGUA SE TRANSFORMAN CANTIDADES EQUIMOLARES DE FOSFATO DIAMONICO Y PENTOXIDO DE FOSFORO A TEMPERATURAS DE 170 A 350 C EN UNA ZONA QUE REALIZA UNA MEZCLA, AMASADO Y DESMENUZAMIENTO CONSTANTES EN PRESENCIA DE GAS AMONIACO CIRCULANTE. EN ESTE CASO, SE SEPARA EL AGUA DEL GAS AMONIACO QUE CONTIENE VAPOR DE AGUA QUE SALE DE LA ZONA Y SE DEJA CIRCULAR DE NUEVO AL GAS AMONIACO SECO A TRAVES DE LA ZONA. UNA INSTALACION PARA LA FABRICACION DE POLIFOSFATO AMONICO EN FORMA DE CADENA, ESENCIALMENTE INSOLUBLE EN AGUA, PUEDE ESTAR CONSTITUIDA POR UN REACTOR (1), EN EL QUE DESEMBOCAN UN TUBO DE ALIMENTACION DE AMONIACO (8) ASI COMO TUBOS PARA LA ALIMENTACION DE PENTOXIDO DE FOSFORO (6) Y FOSFATO DIAMONICO (7) Y DEL QUE PARTEN UN TUBO DE SALIDA DE POLIFOSFATO AMONICO (9) ASI COMO UN TUBO DE GAS DE ESCAPE (10). EL TUBO DE GAS DE ESCAPE (10) DESEMBOCA EN UN REFRIGERADOR (13), QUE ESTA CONECTADO EN CUANTO A LA CORRIENTE CON UN INTERCAMBIADOR DE CALOR (15) A TRAVES DE UNA BOMBA (14). DEL INTERCAMBIADOR DE CALOR (15) PARTE UN CONDUCTO DE GAS DE ESCAPE (18), QUE DESEMBOCA EN EL TUBO DE ALIMENTACION DE AMONIACO (8).
