Abstract

PROCEDIMIENTO PARA TRATAR MEMBRANAS PERMEABLES DEGRADADAS, Y MEMBRANAS RESULTANTES CON PROPIEDADES DE PERMEACION RESTABLECIDAS. EL PROCEDIMIENTO CONSISTE EN QUE LAS MEMBRANAS PERMEABLES, QUE HAN EXPERIMENTADO UNA DEGRADACION EN SU FUNCIONAMIENTO COMO CONSECUENCIA DE SU UTILIZACION, SE CALIENTAN A UNA TEMPERATURA MODERADA DE APROXIMADAMENTE 50GC A 140GC DURANTE UN PERIODO DE TIEMPO SUFICIENTE PARA LOGRAR SU REGENERACION. LAS MEMBRANAS ASI OBTENIDAS SON UTILES PARA SEPARAR SELECTIVAMENTE LOS COMPONENTES DEL AIRE Y OTRAS MEZCLAS GASESOSAS.
