It was deduced that, when loading value increased above 0.01, retention value started to decrease. This unusual behavior was attributed to the decrease in polymer solubility resulting in coiling up of polymer chains. Next, the selectivity of C-PEG polymers on PEUF was investigated with concentrated sea water taken from Çamaltı Salina under varying loading values and the results listed in Table A.3 were obtained. Table A.3 Retention values for concentrated brine taken from Çamaltı Salina in PEUF utilizing C-PEG under pH:7.4 and 25 oC Metal ion Na K Mg Li Loading:0.1 0.060 0.014 0.093 0.086 Retention values (R) Loading:0.01 0.090 0.049 0.134 0.178 Loading:0.001 0.041 0.001 0.136 0.136 It was seen that C-PEG is selective to lithium near sodium and potassium in 2 to 4 folds. For magnesium, the retention values came out to be similar for different loading values. Only when loading value is 0.01, the retention value of lithium seems to be higher than magnesium. At this point, the selectivity values of C-PEG were found as SLi/Na=2, SLi/K=3.6, SLi/Mg=1.3. Even though the selectivity values are below the expectations, when the high concentration of potassium (around 10000 ppm), magnesium (around 20000 ppm) and sodium (around 75000 ppm) near lithium (around 1.25 ppm) is considered, the results were found meaningful for utilizing PEUF method in separation of lithium. After these results were examined, the synthesis of C-PEG was done by different molecular weight PEG methacrylate to highlight the definite separation efficiency of PEUF with C-PEGs. Additional C-PEGs were synthesized having different Mn values (300, 500, 950 and 2000). The most satisfactory results were obtained by C- PEG with a monomer MW around 950 g/mol. The higher MW polymer which was 149PDF 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 (Standard Web Page)
