Abstract
LA INVENCION SE REFIERE A LA SEPARACION DEL FLUORURO DE HIDROGENO (HF) DE SUS MEZCLAS CON EL 1,1,1-TRIFLUORO-2-CLOROETANO (F133A). POR DECANTACION DE LA MEZCLA DE HF Y DE F133A A UNA TEMPERATURA INFERIOR A 0 (GRADOS) C, SE OBTIENE UNA FASE INFERIOR ORGANICA POBRE EN HF Y UNA FASE SUPERIOR RICA EN HF. ESTA ULTIMA PUEDE SER DIRECTAMENTE RECICLADA EN EL REACTOR DE FLUORACION O SOMETIDA A UNA DESTILACION PARA SEPARAR EN CABEZA EL AZEOTROPO HF-F133A QUE SE REENVIA AL DECANTADOR Y RECUPERAR EN PIE EL HF PRACTICAMENTE PURO. POR DESTILACION DE LA FASE INFERIOR, SE SEPARA EN CABEZA EL AZEOTROPO HF-F133A QUE SE REENVIA AL DECANTADOR Y SE RECUPERA EN PIE EL F133A.
