Poly vinyl formamide Formamides are very polar molecules and have strong solvation powers. In Chapter 3.2, alkyl formamides were employed as extraction solvents for lithium chlorides and fairly high distribution coefficient values were acquired in the experiments. Therefore, it was thought that, to synthesize a polymer of vinyl formamide can lead us to high retention values in polymer enhanced ultrafiltration method. The synthesis of poly vinyl formamide was accomplished by addition polymerization technique starting from vinyl formamide monomer. 2,2'-Azobis (isobutyramidine) dihydrochloride was used as an initiator. The final product was dissolved in water and the polymer solution was first filtrated with a membrane having molecular weight cut-off: 3-20 kDa. Adjustment of the pH was done by ammonia-ammonium chloride buffer. The final mixture was fed to the polymer enhanced ultrafiltration (PEUF) set-up and the experiment was repeated for two different pH values at loading:0.01 and 25 oC. The resulting retention values are tabulated in Table A.7 and shown below. Table A.7 PEUF experiment results by poly vinyl formamide Feed conc. (ppm) Permeate conc. (ppm) Retention pH: 8 45.68 44.64 0.023 pH:9 45.165 43.21 0.043 As it can be seen from Table A.7, poly vinyl formamide has no functionality in separation of lithium. Therefore further experiments were not held on. 155PDF Image | SEPARATION OF LITHIUM FROM BRINES

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 |
