molecular weight cut-off 5 kDa. The molecular structure of PES membrane is seen in Figure A.5. Figure A.5 The molecular structure of PES membranes The interaction of lithium ions with PES membrane can be occurred via unshared electrons of sulfone and ether group. Since oxygen atoms tend to be more electrophilic then sulfur atoms, the electron cloud between sulfur and oxygen atoms is oriented towards oxygen, which means slightly negative charge on oxygen atoms. The remaining positive charge on sulfur atom can also be stabilized by the resonance effect of benzene rings in the structure. If we consider that lithium ions present in solution are in Li+ form, an interaction of lithium ions with sulfone group oxygens is predictable. After these findings, the selectivity of membrane towards lithium near foreign ions was questioned and a mixture of lithium, sodium, potassium, magnesium each having a concentration around 10 ppm in solution was fed to the PEUF set-up with the same membrane (PES MWCO: 5 kDa). The results are tabulated in Table A.6. 151PDF 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)
