20120216677 | CONTACTING SYSTEMS AND METHODS AND USES THEREOF - In accordance with the present invention, there are provided systems and methods for contacting two or more fluids, useful, for example for purifying or infusing a fluid (by allowing efficient and/or uniform addition of components to or removal of components from the fluid). The components may be undesirable components to be removed from a fluid, or a desired component or components to be added to the fluid, for example, each of which is referred to herein as “component”. In this regard, the disclosed embodiments provide for the purification or infusion of a fluid by passing a liquid and a fluid through a contacting zone which facilitates intimate mixing of the liquid and the fluid. A differential of partial pressure, activity, fugacity or concentration of the components between the liquid and the fluid facilitates the transfer of the components between the liquid and the fluid in the intimately mixed liquid and fluid. | 08-30-2012 |

20140345458 | REDUCING NITROSAMINE CONTENT OF AMINE COMPOSITIONS - The present invention provides strategies for reducing the nitrosamine content of amine compositions that are contaminated with one or more nitrosamines. The present invention is based apart upon the appreciation that irradiating contaminated amine compositions with a suitable fluence of electromagnetic energy, such as ultraviolet energy, is able to selectively decompose the nitrosamine content relative to the amine content. This allows the amine content of the treated compositions to be preserved. As a consequence, the principles of the present invention are particularly useful for regenerating amine absorbents. Reducing the nitrosamine content so easily also facilitates disposal, further processing, or other desired handling of amine compositions. | 11-27-2014 |
20150114226 | HIGH PERFORMANCE HYDROPHOBIC SOLVENT, CARBON DIOXIDE CAPTURE - Methods and compositions useful, for example, for physical solvent carbon capture. A method comprising: contacting at least one first composition comprising carbon dioxide with at least one second composition to at least partially dissolve the carbon dioxide of the first composition in the second composition, wherein the second composition comprises at least one siloxane compound which is covalently modified with at least one non-siloxane group comprising at least one heteroatom. Polydimethylsiloxane (PDMS) materials and ethylene-glycol based materials have high carbon dioxide solubility but suffer from various problems. PDMS is hydrophobic but suffers from low selectivity. Ethylene-glycol based systems have good solubility and selectivity, but suffer from high affinity to water. Solvents were developed which keep the desired combinations of properties, and result in a simplified, overall process for carbon dioxide removal from a mixed gas stream. | 04-30-2015 |
