Often, the mass transfer zone includes a hollow fiber membrane contactor. | 03-06-2014 |
20140163298 | PROCESS AND VESSEL FOR REMOVING ONE OR MORE SULFUR COMPOUNDS - One exemplary embodiment can be a process for removing one or more sulfur compounds from a first liquid. The process can include passing the first liquid through a first inlet and a second liquid through a second inlet of a vessel, passing the first and second liquids through the passageway for facilitating contacting of the first and second liquids to extract the one or more sulfur compounds from the first liquid to the second liquid, and passing the first liquid through the first outlet and the second liquid through the second outlet. Often, the vessel has a plurality of vortex contactors, and a first outlet and a second outlet. The plurality of vortex contactors can include a first vortex contactor, in turn having at least one wall forming a perimeter about an interior region and including a first side and a second side forming a passageway communicating the first liquid from an exterior to the interior region, and a frustum positioned proximate to the passageway and abutting the at least one wall. | 06-12-2014 |
20140235897 | PROCESS FOR OXIDIZING ONE OR MORE THIOL COMPOUNDS - One exemplary embodiment can be a process for oxidizing one or more thiol compounds from an alkaline stream. The process may include passing a mixed stream having the alkaline stream to an oxidation vessel having a body and a neck. Often, the body contains one or more packing elements and the neck contains a packing, a distributor, and a mesh. The process can further include passing an oxidized alkaline stream to a separation vessel containing a first chamber and a second chamber. Usually, the first chamber contains a coated mesh. | 08-21-2014 |
20140357927 | Apparatus and Process for Removal of Sulfur-Containing Compounds from a Hydrocarbon Stream - A process for removing sulfur compounds from a liquid hydrocarbon stream includes the steps of feeding the hydrocarbon stream to a recirculation section of an extraction vessel wherein the recirculation section contains a first alkaline solution; passing the hydrocarbon stream through the recirculation section; recirculating at least a part of a first alkaline stream to a top deck of one or more liquid-liquid contacting decks of the recirculation section; passing the hydrocarbon stream from the recirculation section to an extraction section of the extraction vessel wherein the extraction section includes one or more liquid-liquid contacting decks; feeding a second alkaline stream to an upper deck of the one or more liquid-liquid contacting decks of the extraction section wherein the second alkaline stream includes a second alkaline solution; and withdrawing a hydrocarbon product stream from the extraction vessel. An apparatus for removing sulfur compounds from the hydrocarbon stream is also disclosed. | 12-04-2014 |
