20140262740 | SEPARATION OF IMPURITIES DURING EXTRACTION PROCESSES - A process for the removal of sulfur compounds from a hydrocarbon stream is disclosed. The process includes extractive distillation of a feed stock coupled with a solvent recovery column having a vapor side draw containing the sulfur compound impurities. | 09-18-2014 |
20140231238 | SEPARATION PROCESSES USING DIVIDED COLUMNS - The claimed invention provides a technique wherein the two column system is combined into a single column. The light components are concentrated on the prefractionation side (feed side) of the column, where they are removed as an overhead top product. The middle boiling components are removed as an overhead product on the opposite side of dividing wall. For the same product specifications, top divided column requires substantially lower capital and operating cost than a conventional two-column system. | 08-21-2014 |
20140197556 | SYSTEM AND METHOD FOR LIQUID DISTRIBUTION - A liquid flow distributor for positioning above one or more packing sections in a packed exchange tower includes a plurality of troughs. At least one trough in the plurality of troughs has along a side thereto a deflecting member The deflecting member is angulated to generally follow a shape of the at least one trough. A diffuser side of the deflecting member is positioned to deposit the liquid into a discharge region. A plurality of break bars are disposed on the diffuser side of the deflecting member. A deflector side of the deflecting member is positioned for deflecting ascending vapor away from the discharge region. | 07-17-2014 |
20140144768 | FLUID CONTACTOR-DIFFUSER TRAY ASSEMBLY - A separations tray assembly for use in a fluid-fluid exchange column. The separations tray assembly is of the type where a first fluid, in a continuous phase, is directed across successive trays in a serpentine flow path. A second fluid, in a dispersed phase ascends through apertures in the tray thus inducing interaction and mass transfer with the first fluid. In accordance with one aspect of the present invention, the separations tray further includes a diffuser skirt, having apertures disposed therein, operatively coupled to a fluid channel. The diffuser skirt is operable to direct the first fluid to cover substantially an entire volumetric cross-flow window between successive separations trays and to induce stirring and mixing of the first fluid and the second fluid to effect efficient mass transfer. | 05-29-2014 |
20140103550 | STRUCTURED PACKING FOR GAS-LIQUID MASS TRANSFER UNIT - [Object] In the existing structured packing, performance depends on the effective contacting area and it decreases in case that large surface tension mixture such as with a lot of water since such mixture are difficult to wet the packing surface. Also they have poor performance for relatively higher liquid load at atmospheric pressure or less and for high pressure system where the ratio of liquid/vapor load becomes relatively higher than non-high-pressure system. | 04-17-2014 |
