Abstract

LA INVENCION CONCIERNE A LA SEPARACION DEL FLUORURO DE HIDROGENO (HF) DE SUS MEZCLAS CON EL 1, 1, 1 ORETANO (F133A). POR DECANTACION DE LA MEZCLA DE HF Y DE F133A EN PRESENCIA DE TRICLOETILENO A UNA TEMPERATURA INFERIOR A 0 C, SE OBTIENE UNA FASE INFERIOR ORGANICA POBRE EN HF Y UNA FASE SUPERIOR RICA EN HF. ESTA ULTIMA PUEDE SER DIRECTAMENTE RECICLADA POR REACTOR DE FLUORACION O SOMETIDA A UNA DESTILACION PARA SEPARAR A LA CABEZA EL AZEOTROPO HF-F133A QUE SE REENVIA AL DECANTADOR Y RECUPERAR AL PIE UNA MEZCLA DE F133A QUE SE REENVIA AL DECANTADOR Y SE RECUPERA AL PIE UNA MEZCLA DE F133A Y DE TRICLOETILENO. ESTA ULTIMA MEZCLA ES SOMETIDA A UNA DESTILACION QUE PERMITE SEPARAR A LA CABEZA EL F133A PURO DEL TRICLOROETILENO AL PIE.
