Abstract

SOLUCIONES ACUOSAS DE RESINAS SINTETICAS SOLUBLES EN AGUA, TALES COMO RESINAS DE UREA Y FORMALDEHIDO, SON CARGADAS EN UNA UNIDAD DE MEMBRANAS DE ULTRAFILTRACION PARA SU SEPARACION EN UNA SOLUCION DE MATERIAL CONCENTRADO Y EN UNA SOLUCION DE MATERIAL PERMEADO. LA SOLUCION DE MATERIAL PERMEADO ES RECIRCULADA A UN REACTOR DE POLIMERIZACION, PREFERIBLEMENTE DESPUES DE HABER SIDO SOMETIDA A OSMOSIS INVERSA PARA REVALORIZAR EL MATERIAL PERMEADO. UNA INSTALACION PARA LA PRODUCCION Y SEPARACION DE RESINAS SINTETICAS, SOLUBLES EN AGUA, COMPRENDE UN REACTOR DE POLIMERIZACION Y UNA UNIDAD DE MEMBRANAS DE ULTRAFILTRACION EN QUE LA SALIDA PARA MATERIAL PERMEADO DE LA UNIDAD DE ULTRAFILTRACION ESTA CONECTADA CON EL REACTOR DE POLIMERIZACION, PREFERIBLEMENTE PASANDO POR UNA UNIDAD DE OSMOSIS INVERSA.
