Abstract

EN EL PROCEDIMIENTO PARA LA PURIFICACION CONJUNTA DE LOS GASES PRODUCIDOS EN LA FABRIACION DE FERTILIZANTES MINERALES MEDIANTE UNA SOLUCION DE LAVADO EN UNA COLUMNA DE LAVADO, EN EL QUE LAS AGUAS DEL PROCESADO CONSTITUYEN AL MENOS UNA PARTE DE LA SOLUCION DE LAVADO, PRESENTANDO LA SOLUCION DE LAVADO UN CONTENIDO DE FOSFATO DE AL MENOS 1 % EN PESO, PREFERENTEMENTE DE AL MENOS 2 % EN PESO, CALCULADO COMO P SUB,2}O SUB,5}, SOLUBLE EN LA SOLUCION CLARA DE LAVADO. PARA ELLO, EL PH DE LA SOLUCION DE LAVADO SE AJUSTA MEDIANTE ACIDOS MINERALES, PREFERENTEMENTE ACIDO NITRICO, A UN PH QUE ESTA EN EL INTERVALO ENTRE 3 Y 5,5, PREFERENTEMENTE A UN PH ENTRE 3,6 Y 4,2. COMO SOLUCION DE LAVADO SE UTILIZAN EN EL PROCEDIMIENTO DE FABRICACION DE FERTILIZANTES MINERALES LAS AGUAS ACIDAS PRODUCIDAS DURANTE EL PROCEDIMIENTO Y LAS AGUAS DE LAVADO, QUE SE AJUSTAN HASTA EL PH REQUERIDO MEDIANTE LA ADICION Y DISOLUCION DE NH SUB,3} O HNO SUB,3}.
