Table 3.23 The selectivity values of hexyl formamide for lithium near foreign (Na, K, Mg, Ca) ions in sea water. pH:4 SLi/Na SLi/Mg Selectivity 2.07 0.57 SLi/K 2.00 SLi/Ca 0.30 SLi/Na 2.29 pH:9 SLi/Mg SLi/K SLi/Ca 0.69 1.57 0.26 Table 3.22 and Table 3.23 imply that the selectivity of HeFo towards lithium compared to potassium and sodium are higher than 1 but lower than 1 for calcium and magnesium ions. The selectivity values do not change very much with respect to changes in pH like in the case of distribution coefficients. Following the calculation of the selectivity values for artificial sea water, selectivity experiments were conducted by the real concentrated brine samples taken from Çamaltı Salina, İzmir. The initial solution composition and acquired distribution coefficients were listed in Table 3.24. Table 3.24 Composition of the concentrated sea water taken from Çamaltı Salina and resulting distribution coefficients (25 oC, 10 ml HeFo/10 ml water, pH:7.4) Metal ion Sodium Magnesium Calcium Potassium Lithium Concentration (ppm) (mg/L) 76750 21000 - 11023 1.25 Distribution Selectivity values coefficient (klithium/kmetal) 0.01 7.8 0.09 0.86 - - 0.01 7.8 0.078 1 Table 3.24 shows that the distribution coefficient values are lower than the values in the experiments conducted for the artificial sea water. The reason of decrease in the values may be additional foreign ions present in sea water, which may compete with lithium ions and reduce the extraction amount. Eventually the distribution coefficient value was found as 0.078 for hexyl formamide, still larger than n-butanol, which shows the solvation power of hexyl formamide. 85PDF 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 |
