filtration stability and reduce the solvent-induced swelling, Song et al. [41] prepared a blend membrane consisting of a sulfonated polyether ether ketone (SPEEK) blend with hydrophobic polyethersulfone (PES) by using a kerosene/TBP extractant. Although the membrane’s mechanical strength and permeate flux remained nearly unchanged after a long-term test in the solvent of kerosene, the SPEEK/PES blend membrane was unstable in some other organic solvents, such as benzene and toluene. Another solvent-resistant commercially available block copolymer poly(ethylene-co-vinylalcohol) (EVAL) was used for the fabrication of a nanoporous membrane [42]. This block-copolymer consisted of hydrophobic solvent-resistant blocks, ethylene, hydrophilic ion-permeable blocks, and vinyl alcohol. The resultant membrane was resistant to a wider range of solvents including benzene, toluene, acetone, sulfonated kerosene, 1-propanol, TBP, DMF, and THF. A stable performance of the EVAL barrier membrane was achieved for > 1000 h [43]. Although extensive research has been carried out to strengthen the long-term stability, the solvent resistance and solvent leakage remain considerable challenges. In addition, the acid/base resistance, process design and cost should be considered to assess the potential of the SLM technology for large-scale applications in practice. Fig. 2.

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)
