| 20110204655 | ENERGY STORAGE SYSTEMS - The present invention provides an energy storage device that utilizes a cold sink that undergoes cycles of freezing and thawing. The device converts electrical energy to stored thermal energy, and then re-converts the stored thermal energy to electrical energy, as needed or desired. The device can store energy on a large scale (e.g., on the order of megawatts or greater) and for an extended period of time (e.g., for at least 12 hours, or longer, as needed). | 08-25-2011 |
| 20110112329 | ENERGY EFFICIENT ACETONE DRYING METHOD - The present invention provides energy and economically efficient and environmentally responsible processes for using acetone to dry, dehydrate and/or dewater various hydrated feedstocks. | 05-12-2011 |
| 20100228000 | NYLON EXTRACTION FROM COMMINGLED MATERIALS - The present invention provides energetically and economically efficient methods for separating polyamide polymer(s) from commingled materials. The methods generally involve precipitating a polyamide polymer dissolved in a solvent (e.g., formic acid) using dimethyl ether (DME) as an antisolvent. The methods comprise dissolving the polyamide polymer in a solvent that (i) selectively dissolves the polyamide polymer relative to the other materials and (ii) has a higher solubility for DME relative to the polyamide polymer; and then contacting the mixture of the solvent with the dissolved polyamide polymer with DME, thereby precipitating the polyamide polymer. | 09-09-2010 |
| 20100069686 | Energy Efficient Separation of Ethanol From Aqueous Solution - The present invention provides methods and systems for extracting ethanol from an ethanol-water solution comprising (1) extracting ethanol from an ethanol-water solution with a first solvent comprising an esterified fatty acid, wherein the esterified fatty acid comprises a hydroxylated fatty acid component and an alcohol component such that the alcohol component is a C | 03-18-2010 |
