an external source of heat. During the evaporation process, sodium chloride, burkeite (3Na2SO4.Na2CO3) and dilithium sodium phosphate (licons) are crystallized. Licons are then converted to phosphoric acid and lithium carbonate by a reaction. In this reaction, licons are firstly baked in an oven and organic residues are cleaned, then licons are reacted with sulfuric acid at 115 oC and splitted into phosphoric acid and lithium, sodium sulfates. Lastly, sulfates react with soda ash and lithium carbonate is obtained [21, p. 134] . 1.4.5 Lakes in Turkey There is no commercial production of lithium compounds in Turkey. Tuz Lake has the highest lithium composition with 325 ppm but high magnesium content in the lake blocks the production of lithium. The composition of ions in some of the lakes in Turkey is listed in Table 1.9 [48]. Table 1.9 The compositon of lakes in Turkey Lake Acı Lake Burdur Lake Tersakan Lake Boluk Lake Tuz Lake Lithium Magnesium Potassium 16 4108 1000 3 970 46 34 6300 2000 36 8800 2000 325 37500 12000 Sodium 46000 5550 23500 50000 61000 1.5 Literature survey on lithium separation methods from brines Lithium is currently produced by evaporation and precipitation processes from brines conventionally. However the high concentration of the foreign ions in brines with lithium, force the researchers to develop an additional method to be integrated in conventional processes. Liquid-liquid extraction and adsorption methods have been the most investigated methods cited in the literature so far. 15

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.
