Model Fitting and ANOVA Analysis The experimental data was used to develop a second-order polynomial model which can be written as: kkkk Y = β0 +βi ×Ai +βij ×Ai ×Aj +βii ×Ai2 +ε (20) i=1 i=1 j=1 i=1 in which β0 is the intercept, βi, βij, βii are first-order, interactive, and second-order effects, respectively, i and j represent the number of k factors, and ε is the residual error [27]. This method is able to evaluate interaction effects and pure quadratic effects, and is considered to be the most efficient evaluation method that can improve the quality of data. ANOVA was used to determine the significance of each term in the equation and estimate the goodness of fitting quality. In the results of this ANOVA analysis the p-values could be used to check the significance of each term. Specifically, values of “probability (p) > F” less than 0.05, 0.01, and 0.001 indicate that the model terms are significant, highly significant, and remarkably significant, respectively, while values greater than 0.05 indicate that the model terms are not significant [28]. The results of ANOVA for the quadratic model of the yield are shown in Table 7. ANOVA revealed that the model was highly significant (p < 0.01) for the yield of Li2CO3 product, indicating that the developed model was reliable. As can be seen from Table 7, significant linear A, highly significant quadratic A2 and C2, and remarkably significant linear C effects on yield were shown by the ANOVA results, while for the other factors, the p-values were greater than 0.05, indicating that these factors were not significant. Based on the regression coefficient (β) values, solution concentration was revealed to be a major effect, followed by temperature, feeding rate, and stirring speed. The yield of the Li2CO3 product can be expressed by the following second order polynomial equation: R(Yield) = 88.82 + 2.19a + 1.21B + 3.85C + 0.092D + 0.76AB − 1.84AC + 0.38AD + 1.60BC − 0.064BD − 0.11CD − 2.54A2 − 0.99B2 − 2.47C2 − 1.08D2 (21)PDF Image | Reactive Crystallization Process of Lithium Carbonate

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)
