extraction. Sodium, potassium, magnesium and calcium ions compete with the lithium adsorption. Therefore, aluminum loaded resin, which some past studies reported that had relatively good selectivity for lithium, was also tested. This resin extracts lithium on the surface in the form of LiCl·2Al(OH)3·nH2O. It showed higher capacity and selectivity than any other resins tested in this study in the saline solution with the value of 6.6 mg/g. Nevertheless, overall, it was found that IX resins poorly suited for lithium recovery. A second study focused on FP as an adsorbent. FP can adsorb lithium ion from solution by a reduction reaction and turns to lithium iron phosphate (LFP). As a second step, an oxidizing agent can strip lithium and regenerate FP. In this project, sodium thiosulfate (TS) or sodium sulfite (SF) was used as a reducing agent. By analyzing X-ray diffraction patterns of the products after the reduction, it was found that FP was successfully reduced to LFP in most cases with faster reaction at a higher temperature. However, when SF was used as a reducing agent for lithium loading from a brine solution containing calcium ions, calcium sulfite salts were produced. In addition, at 65 °C, sodium iron phosphate was formed in addition to LFP. The maximum of lithium adsorption capacity was almost the same value as the theoretical value of 46.0 mg-Li/g-FP. For example, the value was 45.9 mg/g in the case of SF reduction at 65 °C. Lithium selectivity was also high. The selectivity over sodium, for instance, 2541 in the case of SF reduction at 45 °C. When TS and SF are compared as a reducing agent, TS is better when a brine solution contains calcium because SF produces calcium sulfite. On the other hand, SF needs an only half dosage of TS since SF reacts with FP with the ratio of one to two while TS does with the ratio of one to one. There was a pH decrease from around 7 to 4 during experiments, but pH did not have much impact on adsorption capacity. However, 40% of iron was dissolved when TS was used for reduction at 65 °C. This problem of iron dissolution can be prevented by pH control in the neutral region of – 7. When it comes to practical operation, FP should be recycled.

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)
