Abstract

MEMBRANAS COMPUESTAS MEJORADAS, SU FABRICACION Y SU USO. LAS MEMBRANAS CONSTAN DE UN SOPORTE POROSO Y UN REVESTIMIENTO DE SEPARACION COMPUESTO DE UNO O MAS POLI(TETRAMETIL)-BISFENOL A-FTALATOS. EL PROCEDIMIENTO DE FABRICACION CONSISTE EN HABILITAR DICHO SOPORTE POROSO Y UNA SOLUCION DE DICHO MATERIAL DE REVESTIMIENTO, CUBRIR EL SOPORTE CON DICHA SOLUCION Y SECAR LA CAPA DE REVESTIMIENTO FORMADA. EL METODO DE USO COMPRENDE PONER EN CONTACTO UNA MEZCLA GASEOSA CON UNA DE ESTAS MEMBRANAS, DEJAR QUE DICHA MEZCLA ATRAVIESE LA MEMBRANA Y RETIRAR DE SU SUPERFICIE OPUESTA UN PRODUCTO PERMEADO EN EL QUE LOS COMPONENTES DE LA MEZCLA GASEOSA APARECEN EN UNA PROPORCION DIFERENTE DE LA QUE TENIAN ANTES DE LA PERMEACION. EL INVENTO ES UTIL PARA SEPARAR LOS COMPONENTES DEL AIRE Y OTRAS MEZCLAS GASEOSAS.
