20090091139 | Osmotic energy - A process for driving a prime mover, said process comprising a) positioning a selective membrane between a liquid and a solution having a higher osmotic potential than the liquid, such that the solution becomes pressurised by the influx of liquid across the membrane, b) using the pressure generated in the solution to drive a prime mover, c) recovering the solution, d) separating at least some of the solvent from the solution to form a residual product, and e) recycling the separated solvent and/or the residual product of step d) to step a). | 04-09-2009 |
20110051880 | High Efficiency Power Plants - Modified Kalina and modified Mayahi cycle heat engines are disclosed. Improvements in efficiency may be gained through various changes to these cycles as well as combining these cycles with boiling water reactors and other Rankine cycle power plants. | 03-03-2011 |
20110226698 | Dynamic Filtration - A novel dynamic filtration method and apparatus reduce the bio fouling and the scaling on the membrane surface during separation processes. A membrane separator is rotated while receiving feed to be separated into a component and waste. Because of the reduction in bio fouling and scaling on the membrane surface, the useful lives of RO and NF membranes may increase significantly, along with energy savings. | 09-22-2011 |
