According to the graph, almost 40% of iron extracted from FP and the pH went down to 4–5 in B1–B4 solution while sodium thiosulfate solution itself is neutral at around 7. 2FePO4+2LiCl+2Na2S2O3 →2LiFePO4 +Na2S4O6 +2NaCl (5.1) However, as shown in Equation (5.1), there is no acid produced to lower pH and no iron dissolution by the thiosulfate reduction. Ferric phosphate would not dissolve even at 65 °C and at pH 4. Therefore, it is appropriate to guess another reaction which produces proton and dissolves ferric phosphate. The reaction should be involved in thiosulfate because this phenomenon occurred in the thiosulfate case only. Based on these considerations, it is assumed that ferric phosphate is reduced to ferrous sulfate by tetrathionate with the following reaction.

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)
