3.4.1.4 Effect of bead size The size of the beads in the column may change the performance of the system due to mass transfer effects. In order to investigate the effect of bead size on efficiency of the column, two experiments were carried out with two columns filled with different size of beads. The operating parameters of the columns are tabulated in Table 3.34. Table 3.34 The column operating conditions for different bead sizes in adsorption process Run # 3 8 Feed Li conc.

When bead size is increased from 3 mm to 8 mm, the breakthrough curve becomes broader. It is important to note that as the bead size increases, the PSMA content in the beads increases and LiMnO content decreases. 8 mm sized beads can only hold 43 % LiMnO content, while 3 mm sized beads can hold 51 % LiMnO. This brings additional barrier to the diffusion of lithium ions through the beads which have higher PSMA content. Also decrease in the total mass transfer area in the system 101PDF Image | SEPARATION OF LITHIUM FROM BRINES

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 |
