252 The recovery of Li in the loading step approached 91% in our run without optimization. Li 253 recovery efficiency was calculated from the ratio of total Li mass in the strip compared to the 254 total Li mass present in the brine solution. It is a fact that, since the sorbent material must retain a 255 certain amount of LiCl to maintain structural integrity, the eluent will always contain a small 256 level of Li at the minimum. We are currently addressing the question of the optimization of the 257 load-wash-strip cycle conditions as well as minimization of the LiCl concentration in the strip 258 solution to maintain the integrity of the sorbent. Selectivity is also very good for purposes of 259 treating geothermal brine. As shown in Table 1, the Li concentration at the peak strip 260 concentration at BV13 was much higher than that of any of the competing metals. Assuming a 261 fraction is collected at the peak concentration, the grade of LiCl would be excellent in relation to 262 its small concentration relative to the competing ions. Defining the separation factor for lithium 263 over another metal M as SFLi/M = ([Li]strip/[Li]brine)/ ([M]strip/[M]brine), where [Li]strip and [Li]brine 264 denotes the lithium concentration in the strip and brine solutions, respectively, where [M]strip and 265 [M]brine denotes the other metal cation concentrations in the strip and brine solutions, very 266 promising values are obtained, especially for sodium at SF = 34.3 (at BV=13), where BV = Bed 267 Volume; and for potassium at SF = 146.2 (at BV=13). Taking the combined bed volumes of 268 BV13-16, the separation factors improve because of the rapid decrease of concentrations of 269 competing ions. Possible tailing of the lithium concentration at BV16 is evident on stripping, and 270 we will pursue this question in future efforts. Efforts are also being made to modify the LDH 271 sorbent compositions or develop alternate extraction methods to improve Li selectivity and 272 capacity and also remove Na and K efficiently from the eluate solution so that high purity battery 273 grade lithium carbonate products can be successfully developed. 274 13PDF Image | Recovery of Lithium from Geothermal Brine Li AL

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 |
