Abstract

UN METODO PARA RECUPERAR EL HELIO DE UN PROCESO DE FABRICACION DE FIBRAS OPTICAS QUE PERMITE RECUPERARLO DE LA MAYORIA DE LAS ETAPAS DEL PROCESO DE FABRICACION QUE CONSISTE EN UNOS PASOS DE DEPOSICION Y CONSOLIDACION. EL HELIO RECUPERADO SE PUEDE REFINAR A UN NIVEL INTERMEDIO Y A CONTINUACION SE PUEDE SEGUIR REFINANDO HASTA QUE TENGA UNA ALTA PUREZA Y SE PUEDE RECICLAR A AL MENOS UNO DE LAS ETAPAS DEL PROCESO DE FABRICACION. TODO EL HELIO RECUPERADO SOLO SE PUEDE PURIFICAR A UN NIVEL INTERMEDIO PARA SUMINISTRARLO UNICAMENTE A LA ETAPA DE ESTIRADO DE LAS FIBRAS. EN UNA REALIZACION PREFERENTE DE LA INVENCION EL HELIO RECUPERADO SE PUEDE PURIFICAR A UN NIVEL INTERMEDIO Y RECICLAR A LA ETAPA DE ESTIRADO DE LAS FIBRAS MIENTRAS EL RESTO SE SIGUE REFINANDO PARA QUE ADQUIERA UNA GRAN PUREZA Y RECICLARLO A LA MENOS UNA DE LAS OTRAS ETAPAS DEL PROCESO DE FABRICACION.
