precipitation. Alternatively, further concentration and refining would help them separate. Therefore, the ferric phosphate method can recycle the adsorbent (FP) without degradation. 5.7. Kinetics Finally, this section discusses the kinetics of the reactions by both thiosulfate and sulfite. Two models are utilized here. One is the pseudo first-order model and the other is shrinking sphere model. While, as mentioned, the reactions in the system of the FP method are so complicated, kinetic models are simplified here. Only one parameter α, reacted fraction of FP, is included in the kinetic models, and temperature is considered by Arrhenius formula. However, the other factors, such as the concentration of lithium, thiosulfate, sulfite and particle size distribution of FP powder and pH, are ignored for simplification. Furthermore, while the two models assume that the reactions of the FP method are normal chemical reactions, they are also electrochemical redox reactions. That’s why it is also possible to consider kinetics by the Butler-Volmer equation and the Tafel equations if the reactions are electron transfer controlled. Here, this study hands over the electrochemical consideration of kinetics to future works. 5.7.1. KineticModels To begin with, the theory of the two models are reviewed in the following.72 Pseudo first- order model is described as Equation (5.8). (5.8) where α is fraction reacted, k is reaction rate constant, and t is time. By taking the natural logarithm, the equation changes to Equation (5.9) and k is obtained as a slope of plots of ln(1-α) vs. time. da = −ka dt a =1−e−kt - 124 -PDF Image | LITHIUM EXTRACTION FROM BRINE using ion resin

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 |
