3.4.4.2.2 Sweeping of the column with acidic water at pH 6.1 As described in Section 3.4.4.2.1, the column was washed with acidic water at pH 6.1 after Run 12 instead of tap water. The logic behind washing the column with a slightly acidic solution was to increase the swept amount of foreign ions, especially Mg ions, while maintaining the lithium content in the column. After sweeping process, the column was eluted with 0.5 M HCl solution, to have the lithium rich solution finally. The concentration of the elution solution and the summary of the steps up to elution are summarized in Table 3.46. Table 3.46 The elution of the column saturated with artificial brine solution and swept by acidic water at pH 6.1. Run # 12 26 27 Operation Adsorbed amount of ions from artificial brine Amount of ions swept by acidic water Eluted amount of ions by 0.5 M HCl Total volume processed (ml) 37164 2000 350 Li (mg) 11.2 0.984 9.6 Na (mg) Saturated 3350 28.4 K (mg) Saturated 241 21.4 Mg (mg) Saturated 612 82.1 Table 3.46 shows that sweeping the column with an acidic water increases the swept amount of all ions through the column including lithium. However, the swept amount of magnesium ions increases to 612 mg from 509, while swept of lithium ions only increases to 0.984 mg from 0.326 mg. By losing 0.658 mg of lithium, 103 mg of magnesium could be swept through the column. In order to evaluate the effectiveness of the overall process (feeding-sweeping (at pH:6.1)-eluting), the concentration of the artificial brine and the elution solution are compared in Table 3.47. 116PDF 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)
