Abstract

"PROCESSO E INSTALAçãO DE PURIFICAçãO E RECICLAGEM DO HéLIO E SUA APLICAçãO à FABRICAçãO DE FIBRAS óPTICAS". A invenção se refere a um processo e a uma instalação de purificação do hélio impuro. De acordo com o processo, o hélio é submetido pelo menos a duas etapas sucessivas de (a) refrigeração criogênica do hélio impuro, de maneira a eliminar por condensação pelo menos uma parte das impurezas principais que ele contém e recuperação de hélio de pureza intermediária, contendo impurezas residuais, e (b) permeação de pelo menos uma parte do hélio de pureza intermediária proveniente da etapa (a), de maneira a eliminar pelo menos uma parte dessas impurezas residuais e recuperação de hélio, com uma pureza final superior a essa pureza intermediária. Esse processo e essa instalação são aplicáveis à purificação do hélio impuro recuperado à saída de um compartimento de resfriamento de fibra óptica, previamente à reintrodução do hélio assim purificado nesse compartimento de modo a reciclar o hélio.
