Abstract

SE DESCRIBE UN PROCESO CONTINUO DE BAJO COSTO PARA SEPARAR Y PURIFICAR ZIRCONIO Y HAFNIO, QUE ELIMINA LOS RESIDUOS LIQUIDOS Y FACILITA EL MANEJO DE RESIDUOS RCRA Y LLW. SE PREPARA UNA SOLUCION ACUOSA DE ZIRCONIO Y HAFNIO, QUE CONTIENEN UNA SOLUCION DE ALIMENTACION, Y ES ALIMENTADA A UN CROMATOGRAFO ANULAR ROTATORIO CONTINUO QUE CONTIENE UN LECHO DE UNA RESINA DE INTERCAMBIO ACIDO. UN ELUYENTE ACIDO, TIPO ACIDO HIDROCLORIDRICO, NITRICO, FOSFORICO O SIMILAR, ES ALIMENTADO A TRAVES DEL LECHO DE INTERCAMBIO ACIDO, MIENTRAS QUE ROTA EL CROMATOGRAFO, QUE SEPARA EL COMPUESTO DE ALIMENTACION EN ZIRCONIO PURO Y HAFNIO Y EN LAS FRACCIONES RESIDUALES RCRA Y LLW. EL ZIRCONIO Y HAFNIO SON PROCESADOS POSTERIORMENTE EN METALES DE ZIRCONIO Y HAFNIO DE CALIDAD NUCLEAR. EL ELUYENTE ACIDO ES RECICLADO PARA SU REUTILIZACION EN EL CROMATOGRAFO Y LAS FRACCIONES RESIDUALES RCRA Y LLW SON EXTRAIDAS EN FORMA SOLIDA.
