20090107890 | Desulfurization of whole crude oil by solvent extraction and hydrotreating - A high sulfur content crude oil feedstream is treated by mixing one or more selected solvents with a sulfur-containing crude oil feedstream for a predetermined period of time, allowing the mixture to separate and form a sulfur-rich solvent-containing liquid phase and a crude oil phase of substantially lowered sulfur content, withdrawing the sulfur-rich stream and regenerating the solvent, hydrotreating the remaining sulfur-rich stream to remove or substantially reduce the sulfur-containing compounds to provide a hydrotreated low sulfur content stream, and mixing the hydrotreated stream with the separated crude oil phase to thereby provide a treated crude oil product stream of substantially reduced sulfur content and without significant volume loss. | 04-30-2009 |

20100264065 | MEMBRANE DESULFURIZATION OF LIQUID HYDROCARBON FEEDSTREAMS - The process of the present invention is directed to the desulfurization of a sulfur-containing unrefined hydrocarbon stream with a membrane separation apparatus, where sulfur compounds are concentrated in a sulfur-rich stream on a permeate side of the membrane, and a sulfur-lean stream is recovered as a retentate. The sulfur-rich stream, which has a small volume relative to the original unrefined hydrocarbon stream, is conveyed to a subsequent desulfurization apparatus or system, such as a hydrotreating system, to recover the hydrocarbons associated with the organosulfur compounds. The stream desulfurized by conventional processes, such as hydrotreating, and the hydrocarbons desulfurized by the membrane separation apparatus may be combined to provide a low sulfur hydrocarbon effluent with minimal or no loss of the original volume. | 10-21-2010 |
20110253595 | COMBINED SOLID ADSORPTION-HYDROTREATING PROCESS FOR WHOLE CRUDE OIL DESULFURIZATION - A whole crude oil desulfurization system and process includes a combination of an adsorption zone and a hydroprocessing zone. This combined process and system reduces the requisite throughput for the hydroprocessing unit, conventionally a very costly and process both in terms of energy expenditures and catalyst depletion. By first contacting the whole crude oil feedstock with an adsorbent for the sulfur-containing compounds, the adsorption effluent having a relatively lower sulfur content can be collected and provided to refiners without further treatment. The adsorbates, including adsorbed organosulfur compounds, are solvent desorbed resulting in a stream containing high levels of organosulfur compounds and a solvent. Following recovery of the solvent, the volume of the sulfur-containing feedstream that remains to be desulfurized in the hydroprocessing zone is substantially less than the original amount of whole crude oil feedstock. | 10-20-2011 |
20120132589 | SUPPORTED IONIC LIQUID MEMBRANE SYSTEM AND PROCESS FOR AROMATIC SEPARATION FROM HYDROCARBON FEEDS - A system and process for treating a hydrocarbon feed mixture containing aromatic compounds is provided to separate the at least one aromatic compound from the hydrocarbon feed stream is provided. A supported ionic liquid membrane, which is a microporous polymeric support containing ionic liquid in its pores, is used to selectively extract aromatics. The hydrocarbon feed mixture is directed to a retentate side of the supported ionic liquid membrane. A permeate stream is drawn from the permeate, side of the supported ionic liquid membrane, which is an aromatic-rich hydrocarbon stream. An aromatic-lean hydrocarbon stream, which is the retentate portion of the original hydrocarbon feed, remains on the retentate side of the supported ionic liquid membrane. | 05-31-2012 |

20130048542 | DESULFURIZATION OF HYDROCARBONS BY SOLVENT EXTRACTION - A high sulfur content hydrocarbon feedstream is treated by mixing one or more selected solvents with a sulfur-containing feedstream for a predetermined period of time, allowing the mixture to separate and form a sulfur-rich solvent-containing liquid phase and a crude oil phase of substantially lowered sulfur content, and withdrawing the sulfur-rich stream and regenerating the solvent. | 02-28-2013 |
20130075305 | SELECTIVE LIQUID-LIQUID EXTRACTION OF OXIDATIVE DESULFURIZATION REACTION PRODUCTS - The present invention provides selective extraction of sulfoxides, or sulfoxides in combination with sulfones, from hydrocarbon mixtures containing these compounds.
