| 20090134090 | SEPARATING COMPONENTS OF AQUEOUS MIXTURES, SUSPENSIONS, AND SOLUTIONS - Systems and methods are described for separating components of aqueous mixtures, including aqueous solutions and suspensions. In one implementation, an apparatus flows the aqueous mixture over a hydrophilic surface to form a first region of purified water and a second region of at least one concentrated non-aqueous component. The apparatus can draw off either the purified water or the concentrated non-aqueous components. In one implementation, an array of tubules performs the differential extraction. In another implementation, various hydrophilic and/or hydrophobic surfaces are disposed in multiple differential extractors and some effluents may be recycled to perform complex assaying and separation. In a further implementation, an apparatus can draw off purified water just beneath the air-water interface. | 05-28-2009 |
| 20120125836 | SEPARATION APPARATUS AND PROCESSES - An apparatus may include a separator and/or a discharger. A separator may include a separator channel, an influent portion configured to allow the passage of a first fluid into a separator channel, an effluent portion disposed above an influent portion and/or a fluid-lift portion between an influent portion and an effluent portion. A discharger may be disposed below a fluid-lift portion and/or may include a portion external to a separator channel, which may include a downward angle relative to an effluent portion and/or may be configured to minimize the passage of a second fluid into a discharger as the second fluid buoyantly travels in a separator channel from an influent portion to an effluent portion. A second fluid may have a density that is less than the density of a first and/or may be configured to lift a first fluid to a fluid-lift portion. | 05-24-2012 |
| 20140001116 | MICROFLUIDIC EXTRACTION DEVICE HAVING A STABILIZED LIQUID/LIQUID INTERFACE | 01-02-2014 |
| 20140238929 | PROCESS FOR PREPARING AN AROMATIC AMINE AND APPARATUS THEREFOR - The invention relates to a process for obtaining at least one aromatic amine from a liquid mixture comprising water and the at least one aromatic amine by extracting with at least one nitroaromatic in an extraction column ( | 08-28-2014 |
| 20160130681 | SOLVENT EXTRACTION SETTLER ARRANGEMENT - In a solvent extraction settler arrangement the outlet box comprises an inner tube arranged vertically inside a shaft, the inner tube being spaced from the side wall of the shaft to define an intermediate space between the inner tube and the shaft. The inner tube has an inner space and an opening at the lower part of the inner tube adjacent the bottom to form a flow path for the heavy solution phase to flow to the inner space. The shaft comprises a second outlet which is separate in relation to the discharge outlet and above the level of the discharge outlet. The second outlet opens through the side wall to the intermediate space at a location adjacent to the upper end of the shaft and at the level of said layer of entrained light solution phase for discharging said layer of entrained light solution phase from the intermediate space. | 05-12-2016 |
