| titleOfInvention | The production method of high-purity hydrogen lithia |
| abstract | The present invention relates to a kind of production method of high-purity hydrogen lithia, its crystalline mother solution waste water after producing potassium chloride as raw material with salt lake bittern, wherein Mg/Li ratio are 200 500:1, by obtaining qualified eluent after ion sieve absorption, wash-out, eluent obtains reverse osmosis concentrated liquid after ultrafiltration membrane technique, segmented nanofiltration, external regeneration are continuously processed from the technology of friendship and reverse osmosis technology.Wherein magnesium ion content is≤30ppm, and lithium ion content is about 4 6g/L, and sodium ions content is 3 5g/L, and calcium ion content is≤5ppm, and the 30ppm of sulfate ion content 1, boron content is≤400ppm.With reverse osmosis concentrated liquid as raw material, technological process is the present invention：Super-pressure counter-infiltration it is continuous from hand over boron removal, it is continuous from hand over engaging sulphate, electrolysis with ion-exchange film, crystallization and evaporation, from handing over boron removal technology, ion-exchange membrane electrolysis, crystallization and evaporation technology, so as to obtain high-purity hydrogen lithia, and by-product boric acid and NaOH, the continuous controllable, extract yield of technical process is high, low production cost, it is easy to industrialize. |
