Abstract

SE PRESENTA UN PROCESO PARA SEPARAR Y RECUPERAR UNA FASE ORGANICA (POR EJEMPLO FLUOROCARBONOS TALES COMO CLOROFLUOROCARBONOS, HIDROCLOROFLUOROCARBONOS, HIDROFLUOROCARBONOS Y PERFLUOROCARBONOS), A PARTIR DE UNA CORRIENTE DE SUMINISTRO DE UNA MEZCLA FLUOROCARBONOS Y FLUORURO DE HIDROGENO, EN DONDE LA MEZCLA SE CARACTERIZA COMO FORMADORA DE AL MENOS UNA COMPOSICION DE AZEOTROPO O SIMILAR AL AZEOTROPO QUE COMPRENDE AL MENOS UN FLUOROCARBONO Y FLUORURO DE HIDROGENO, HACIENDO PASAR LA CORRIENTE DE SUMINISTRO DE LA MEZCLA DE FLUOROCARBONO/HF A TRAVES DEL LADO DE SUMINISTRO DE UNA MEMBRANA SEMIPERMEABLE Y POSTERIORMENTE SEPARANDO ADICIONALMENTE LA CORRIENTE DE FLUORURO DE HIDROGENO DE LA QUE SE HA ELIMINADO EL FLUOROCARBONO Y HACIENDO SALIR UNA CORRIENTE RESIDUAL ENRIQUECIDA CON FLUOROCARBONO DE LA UNIDAD DE MEMBRANA MEDIANTE DESTILACION CONVENCIONAL. UNA FASE DE FLUOROCARBONO ESENCIALMENTE PURO Y UNA FASE DE FLUORURO DE HIDROGENO SE RECUPERAN A PARTIR DE LA DESTILACION SIENDO RECICLADO EL MATERIALDESTILADO DE AZEOTROPO O SIMILAR AL AZEOTROPO EN LA ENTRADA DE LA UNIDAD DE MEMBRANA SEMIPERMEABLE.
