Regeneration of formamides: The regeneration of formamides was done by using hydrochloric acid solution at different pH. After the extraction process, the resulting formamides were taken in a separate flask and mixed with acid solution. Following the vigorous shaking at 25 oC in a separation funnel, 1 hour was allowed in order to have phase separation completely. The results were tabulated in Table 3.25. Table 3.25 The effect of pH on recovery of lithium from hexyl formamide Hexyl (a) formamide Co amount (g) (ppm) Acid C (b) volume (ml) (ppm) pH of the solution The percent recovery of LiCl (%) 10 1.6 10 0.15 1 91 10 1.6 10 0.16 2 90 10 1.6 10 0.19 3 88 10 1.6 10 0.14 4 92 (a) Initial Li concentration in hexyl formamide, (b): Final Li concentration in hexyl formamide. It is seen that the pH of the acidic solution used to recover lithium from hexyl formamide does not affect the percent recovery amount which is around 90 %. The recovery of lithium ions from hexyl formamide can be further repeated by addition of acidic solutions into remaining hexyl formamides. The recovery amount is again observed as 90 % as shown in Table 3.26.

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)
