3.4 Separation of lithium by PSMA-LiMnO beads in an adsorption column Column experiments with PSMA-manganese oxide adsorbents were first done with artificial brine solutions in order to quantify the column performance. The main parameters that affect the performance of the column are pH, feed concentration, flow rate and particle size of the beads. The column dimensions and adsorbent amount was fixed for all experiments. All the experiments were performed with the same bead which was labeled as T16. The MnO2 content of T16 is 51 %. The column diameter is 20 mm, the column height is 385 mm and total weight of the beads is 38.5 g. Bead size is 3mm in size unless otherwise stated. 3.4.1 The breakthrough plots for solutions containing lithium chloride only 3.4.1.1 Effect of pH The most critical parameter that affects the behavior of adsorption process is pH. As explained in Section 3.3.1, increase in pH strictly improves the capacity of LiMnO particles. On the other hand, the swelling ratio of PSMA content in the beads increases at high pH. Swelling of the beads increases the transfer rate of lithium ions in and out, however reduces the flow rate in the column. At pH values higher than 9, flow in the column was even cut down by the expansion of the beads. Therefore the maximum pH value was determined as pH:9.0 by the restriction of swelling behavior of the beads. The minimum pH value was chosen as 7.5, where the activity of LiMnO particles becomes significant. Three experiments were performed at pH: 7.5, 8.2 and 9.0. The column conditions were tabulated in Table 3.31. 95PDF 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 |
