Abstract

LAS AGUAS RESIDUALES, QUE SE OBTIENEN DURANTE LA PRODUCCION DE ACRILONITRILO, PUEDEN SER DEPURADAS FIJANDOLAS EN UN VALOR DE PH DE 4 A 9 Y SOMETIENDOLAS, A CONTINUACION, A UNA INVERSION OSMOTICA EN UNA MEMBRANA A UNA TEMPERATURA DE 10 A 50 GRADOS C Y A UNA PRESION DIFERENCIAL DE 10 A 80 BAR. LA VELOCIDAD DE FLUENCIA EN LA MEMBRANA SE FIJA EN UN VALOR DE 0,5 A 4 M/SEG. EL CONCENTRADO SE AÑADE AL PROCESO DE FABRICACION DE ACRILONITRILO.
