Abstract
GASES CON NOX RESULTANTES EN LA PRODUCCION DE FERTILIZANTES MEDIANTE LA DISGREGACION DE FOSFATOS NATURALES CON ACIDO NITRICO, SE EXTRAEN MEDIANTE ABSORCION EN UN LIQUIDO DE LAVADO. PARA ELLO LOS GASES SE LAVAN EN UNS SOLUCION DE NITRATO DE AMONIO, CUYA CONCENTRACION SE MANTIENE EN VALORES DE 5 A 30% EN PESO Y EL VALOR PH AÑADIENDO AMONIACO EN 3 A 7. LA TEMPERATURA A MAXIMO 40 C. LA SOLUCION DE NITRATO DE AMONIO CARGADA CON NOX SE CALIENTA EN UNA ESCALA DE REGENERACION A POR LO MENOS 55 C Y UNA VEZ QUE DEJA LA ESCALA DE REGENERACION VUELVE DE NUEVO A LA TEMPERATURA DE LA ESCALA DE LAVADO, VOLVIENDO EN PARTE A ESTA.
