Synthesis of the Hybrid Nanocomposite Sorbent Hybrid nanocomposite sorbent beads were prepared by suspension and radical polymerization of the lithiated monomer with a crosslinking agent in the presence of LMO powder. Once the polymerization was completed, the hybrid sorbent beads were collected by filtration, washed, and dried. Sorbent beads typically had a diameter greater than 250 microns. The sorbent beads were treated with an acidic solution to extract lithium, before they were tested for their lithium extraction properties. Hybrid sorbent beads with different compositions were prepared. The composition of the lithium-imprinted polymer and the ratio of the inorganic ion sieve versus lithium-imprinted polymer were varied. The resulting hybrid sorbent beads were evaluated for their physical and chemical properties, and then for their ability to extract lithium from brines. During the program, SRI developed two main hybrid sorbent formulations. The second- generation sorbent beads, prepared using a simplified synthetic procedure, were found to have enhanced lithium capacity. For both sorbent formulations SRI demonstrated that the sorbent beads can be reproducibly prepared at the lab scale in tens of gram quantities. Lithium Extraction Tests The goal of this task was to perform an initial evaluation of the newly prepared hybrid sorbent beads and assess their lithium extraction properties. The hybrid sorbent beads were tested in a fixed-bed configuration to determine its capacity and selectivity. Initial tests were performed using an aqueous solution of hydrochloric acid to regenerate the sorbent. In these experiments, a lithium-containing brine is fed into a column of sorbent, and the composition of the exiting brine is measured as a function of time, until the exit composition matches the feed composition. Taking into consideration the fact that the composition of geothermal brines can vary widely depending on the source reservoir, SRI tested the sorbent performance at various temperatures, pH values, and concentrations of competing metals using synthetic brines. Synthetic brines were prepared using the specified metal chlorides. The pH values of the brines were controlled using buffer solutions from pH 5 up to pH 7. The sorbent beads were suspended in water and loaded into a jacketed column with a diameter of 1 centimeter (cm) and height of 30 cm. The actual height of the packed bed depended on the amount of sorbent loaded. The column temperature was controlled by circulating water at a constant temperature through the column jacket. The brine flow rate was controlled by a constant-displacement pump. The outlet solution was collected in consecutive fractions, and each fraction was analyzed for its lithium concentration using ion-exchange chromatography. After the adsorption was complete, the sorbent was regenerated using an aqueous solution of hydrochloric acid. The regenerated solution was collected and analyzed for total lithium content to provide a measurement of lithium capacity. The lithium separation coefficients were calculated as follows: Li/M =QLi/CLi *CM /QM 12PDF Image | Selective Recovery of Lithium from Geothermal 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)
