CHAPTER 4 CONCLUSIONS 4 CONCLUSIONS The aim of this study is to increase the efficiency of lithium separation from brines by liquid-liquid extraction and adsorption methods with various materials synthesized throughout the study. The conclusions driven from the study can be divided into three parts in terms of the techniques employed. Liquid-liquid extraction - Hexyl, octyl, dibutyl and dihexyl formamides were synthesized by direct reaction of formic acid and related alkyl amines in high yields. - Among those formamides, hexyformamide showed the highest distribution coefficient 0.14 (at 25 oC and pH=4) for LiCl extraction. This is the highest value cited in the literature for a single solvent so far. - The LiCl extraction process was shown to be highly selective for Li, compared to Na, K ions. - Li selectivity is somewhat low with respect to calcium ions. However calcium ions are generally absent in concentrated sea water due to its precipitation as sulfates and carbonates during evaporation in ponds. - It was found that extracted lithium could be eluted with 1.0 M HCl solution, so that 93 % lithium was stripped in the first contact.

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 |
