An- Water-soluble hydroxy-chloride having other benefit of combining costs for LiCI a composition of 5AlC13:8Al(OH)3:37.5HzO recovery with those for power generation has been obtained during leaching of kaolinitic clays, but it is not known whether this specie can be formed from ACH. The next largest cost factor is fuel oil for spray drying. Other drying tech- niques, such as multiple-effect evapora- tion, might decrease the cost, but a final spray drying step would be needed to eliminate pulverization of the solid mixed chlorides. Part of the heat re- quirements for evaporation may be ob- tained from steam available from a power generation plant after the steam exits the turbine. The low-grade steam could extract part of the heat from the is the water balance. Steam used to gen- erate electricity is presently condensed and returned to the injection well to maintain reservoir pressure. Since the condensed steam is potable water, mini- mizing the amount returned to injection would provide a valuable byproduct. Treatment of the spent brine at a 50-MW powerplant for lithium recovery increases the mass from 42,000 to 43,948 tpd. Of the increase, 1,721 tpd is water added with the reagents. The remaining 227 tpd is due to added reagents and the chemical reactions taking place. This 227 tpd represents 54,500 gpd of potable water, which would not need to be injected. SUMMARY AND CONCLUSIONS A lithium recovery system in which brine returning to an injection well from a power generation facility may be treat- ed to recover a lithium chloride product was devised. Each unit operation was mately equal to the present market price studied and gave at least 95-pct lithium but could be decreased by combining lith- recovery. Overall lithium recovery was ium recovery with some of the operations 89 pct. The lithium product contained used in power generation instead of 330 giL LiCl, was 99.9 pct pure, and treating it as an isolated process. REFERENCES 1. Carter, J. P., F. x.

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 |
