Title (EN) METHOD AND APPARATUS FOR THE TREATMENT OF WATER WITH THE RECOVERY OF METALS
(FR) MÉTHODE ET APPAREIL POUR LE TRAITEMENT DE L'EAU AVEC RÉCUPÉRATION DE MÉTAUX
Abstract:
(EN) A method of recovering lithium from energy process water includes the steps of: removing alkaline earth metals from the water; passing the treated water through a reactor column containing a titanium oxide molecular sieve that adsorbs lithium ions; eluting the lithium ions from the molecular sieve using a strong acid solution; and collecting the resulting lithium-rich eluate fluid from the reactor column. The reactor column may include a diffuser core at the inlet tapered from a wider base to a narrow inner end as well as a first screen through which the fluid flows. Fluid exits the inner volume of the column through an outlet tube including a mounted end and walls that taper from the mounted end to a narrower tip; the walls include a second screen through which the fluid flows.
(FR) Une méthode de récupération de lithium à partir d'eau de traitement énergétique comprend les étapes consistant à : éliminer les métaux alcalino-terreux de l'eau ; faire passer l'eau traitée à travers une colonne de réacteur contenant un tamis moléculaire d'oxyde de titane qui adsorbe les ions lithium ; éluer les ions lithium à partir du tamis moléculaire à l'aide d'une solution d'acide fort ; et collecter le fluide d'éluat riche en lithium obtenu à partir de la colonne de réacteur. La colonne de réacteur peut comprendre un coeur de diffuseur au niveau de l'entrée effilée d'une base plus large à une extrémité interne étroite ainsi qu'un premier écran à travers lequel s'écoule le fluide. Le fluide sort du volume interne de la colonne à travers un tube de sortie comprenant une extrémité montée et des parois qui se rétrécissent de l'extrémité montée à une pointe plus étroite ; les parois comprennent un second écran à travers lequel s'écoule le fluide.
