Processes and systems for preparing lithium hydroxide |
摘要 |
There are provided processes for preparing lithium hydroxide. The processes comprise submitting an aqueous composition comprising lithium sulfate and/or lithium bisulfate to a first electromembrane process that comprises a two-compartment membrane process under suitable conditions for conversion of the lithium sulfate and/or lithium bisulfate to lithium hydroxide, and obtaining a first lithium-reduced aqueous stream and a first lithium hydroxide-enriched aqueous stream; and submitting the first lithium-reduced aqueous stream to a second electromembrane process that comprises a three-compartment membrane process under suitable conditions to prepare at least a further portion of lithium hydroxide and obtaining a second lithium-reduced aqueous stream and a second lithium-hydroxide enriched aqueous stream. There are also provided systems for preparing lithium hydroxide. |
