Daoud, Yokohama, Yoshizuka Li concentration in geothermal water is about a hundred fold higher than that in seawater. But, the reasonable recovery technique of Li has not been developed. The purpose of this project study is to learn basic chemistry required to develop a new technique in future for recovery of Li from geothermal water. 4. Experimental 4.1 Materials The geothermal water sample used in this report comes from Obama binary power plant located in Obama, Unzen, Nagasaki Prefecture, Japan. Led by Koyo Denki Co., Ltd. The properties of the geothermal water samples used are listed in Table 1 Table 1: Reported physico-chemistry geothermal water samples (averaged concentration) Parameters Value Concentration (mg/L) pH 8,53 EC (mS/ cm) 1.475 TDS (g/l) - Salinity - B( mg/L) 14.7 Cations Li + Na+ K+ NH4+ Ca2+ Mg2+ Concentration (mg/L) Anions 5.2 HCO3- 2540 F- 259 Cl- 17 NO3- 194 SO4- 212 217 0.5 4590 - 379 The polymer iron sulfate solution of chemical formula FeSO4・7H2O of molar mass 278.01 g/mol was used to remove silicic acid before recovery experiment of lithium. For Li extraction, λ-MnO2 was used as an adsorbent of Li. λ-MnO2 adsorbent in granulated form was produced and supplied from The University of Kitakyushu, Japan. The preparation procedure is the same as that mentioned in the literature. [Yoshizuka and Nalan Kabay 2018]. The properties of λ-MnO2 adsorbent are summarized in Table 2. Table 2. Properties of λ-MnO2 adsorbent. Type Spinel Form granulated Specific surface area, m2/g Mean particle size, mm 1.4 Total lithium capacity, mg Li/g -* 1.0 – 5.0 Other reagents used in this study were of analytical reagent grade. All of the solutions were prepared with ultrapure water.PDF Image | Recovery of Lithium from Geothermal Water

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)
