Abstract

UN PROCEDIMIENTO PARA TRATAR LAS FRACCIONES DE FONDO DE UNA TORRE DE ENFRIAMIENTO BRUSCO PRODUCIDAS POR UNA UNIDAD DE PURIFICACION Y RECUPERACION DE ACRILONITRILO O METACRILONITRILO. LAS FRACCIONES DE FONDO DE LA TORRE DE ENFRIAMIENTO CONTIENEN AGUA, SULFATO DE AMONIO Y UN MATERIAL ORGANICO PESADO. SE CONCENTRAN DICHAS FRACCIONES HASTA QUE ESTEN AL MENOS EL 50%, Y PREFERENTEMENTE EL 90%, SATURADOS DE SULFATO DE AMONIO. SE PONEN ENTONCES EN CONTACTO CON ACETONITRILO PARA EXTRAER EL MATERIAL ORGANICO PESADO, COSA QUE SUCED EXTRAYENDO POLIMERO DE DICHAS FRACCIONES EN UNA PLURALIDAD DE ETAPAS DE EXTRACCION QUE TRABAJAN EN CONTRACORRIENTE, Y SIENDO EN LA ULTIMA DE DICHAS ETAPAS CUANDO SE PRODUCE UNA FASE ORGANICA QUE COMPRENDE DICHO MATERIAL ORGANICO PASADO DISUELTO EN ACETONITRILO Y UNA FASE ACUOSA QUE COMPRENDE SULFATO DE AMONIO DISUELTO EN AGUA.
