51 As lithium has gained importance as a near-critical element for use in various energy storage 52 applications,7 there are continuing efforts to develop simple and inexpensive methods for the 53 recovery of lithium. For example in a typical 50 MW geothermal plant in the Salton Sea, USA, 54 15,000 tons of lithium carbonate or hydroxide salts can be produced annually by recovering and 55 converting of lithium chloride from the geothermal plant waste solutions.8 In addition, there are 56 about 390 MW of geothermal power currently produced in the Salton Sea Known Geothermal 57 Region (SSKGR), USA from the deep geothermal resource.8 This is approximately equivalent to 58 120,000 tons of lithium carbonate production. Hence, the lithium salts produced from geothermal 59 brine solutions will be potentially low-cost and provide a significant supply of lithium resources. 60 Compared to recovering lithium from hard-rock mining, conventional recovery from brine is 61 much cheaper, eco-friendly and simple, as it only involves evaporating the brine under solar heat 62 to achieve the lithium product.9 However, this evaporation process has drawbacks such as low 63 lithium grades, high dispersions of compositions, uncertainty of recovery rate, and a series of 64 time-consuming steps.1 Various alternative methods such as ion exchange (adsorption),10-13 65 hydrometallurgy,4 and solvent extraction14 have been developed to extract lithium from naturally 66 occurring brine solutions. For example, An et al.4 used a two-stage hydrometallurgy process to 67 recover lithium from brine collected from Salar de Uyuni, Bolivia. On the other hand, ion 68 exchange utilizing resins or sorbent materials is suitable for the recovery of lower concentrations 69 of Li ions from brines. Several sorbents such as manganese oxides,10-11, 13 and layered hydrogen 70 titanate, H2TiO312 have been evaluated for lithium recovery. Nevertheless, the quality of the 71 current developed sorbent materials is not completely satisfactory in terms of recovery 72 efficiency, Li capacity, selectivity relative to other competing bulk ions, and stability. More 73 efficient sorbent materials and associated process technology for lithium extraction are therefore 3PDF Image | Recovery of Lithium from Geothermal Brine Li AL

Product and Development Focus for Infinity Turbine
ORC Waste Heat Turbine and ORC System Build Plans: All turbine plans are $10,000 each. This allows you to build a system and then consider licensing for production after you have completed and tested a unit.Redox Flow Battery Technology: With the advent of the new USA tax credits for producing and selling batteries ($35/kW) we are focussing on a simple flow battery using shipping containers as the modular electrolyte storage units with tax credits up to $140,000 per system. Our main focus is on the salt battery. This battery can be used for both thermal and electrical storage applications. We call it the Cogeneration Battery or Cogen Battery. One project is converting salt (brine) based water conditioners to simultaneously produce power. In addition, there are many opportunities to extract Lithium from brine (salt lakes, groundwater, and producer water).Salt water or brine are huge sources for lithium. Most of the worlds lithium is acquired from a brine source. It's even in seawater in a low concentration. Brine is also a byproduct of huge powerplants, which can now use that as an electrolyte and a huge flow battery (which allows storage at the source).We welcome any business and equipment inquiries, as well as licensing our turbines for manufacturing.CONTACT TEL: 608-238-6001 Email: greg@infinityturbine.com (Standard Web Page)
