When the brine was pretreated with the effect of pH at an Al:Li mole ratio of 4 (fig. 3). The data for both figures were obtained at 75° C. More than 95 pet of the lithium was precipitated when the Al:Li mole ratio was at least 2.5 and at pH of 6 to 8. Bench-scale tests verified that these conditions precipitated at least 95 pet of the lithium from the brine. lime within a few days of lithium precip- itation, more than 95 pet of the lithium was precipitated. The causes of aging were not investigated because the lithium recovery flow scheme employed lime pre- treatment immediately before lithium pre- cipitation and aging was not a factor.

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 | RSS | AMP |
