| 208290000 | With organic compound | 11 |
| 20090090655 | Additive Useful for Stabilizing Crude Oil - Crude oils, especially heavy crude oils that are subject to instability on storage or during transportation can be treated with additives in order to stabilizer the crude oil in regard to precipitating contaminants such as asphaltenes. Alkylphenol resins with at least a second component selected from the group consisting of a fatty acid amides, mannich resins and mixtures thereof are effective additives for stabilizing crude oils. | 04-09-2009 |
| 20110297587 | Methods and Systems for Removing Fines From Hydrocarbon-Containing Fluids - A method of removing fines from a hydrocarbon-containing fluid can include preparing a bed media of particulate earthen material ( | 12-08-2011 |
| 20140183101 | Carbon Dioxide Fractionalization - A method comprises separating a hydrocarbon feed stream having carbon dioxide into a heavy hydrocarbon stream and a light hydrocarbon stream. The light hydrocarbon stream is separated into a carbon dioxide-rich stream and a carbon dioxide-lean stream. At least a portion of the carbon dioxide-lean stream is fed to a hydrocarbon sweetening process. Another method comprises receiving a hydrocarbon feed stream that comprises 30 molar percent to 80 molar percent carbon dioxide. A heavy hydrocarbon stream is separated from the hydrocarbon feed stream, wherein the heavy hydrocarbon stream comprises at least 90 molar percent C | 07-03-2014 |

| 20110127195 | DEMULSIFYING COMPOSITIONS AND METHODS FOR SEPARATING EMULSIONS USING THE SAME - The present invention provides for a demulsifying composition comprising the reaction product of an oxirane or oxetane compound (I) comprising at least two oxirane or oxetane groups; a compound (II) comprising silicon and one or more amino groups; and optionally a polyamine (III); and a secondary amine (IV). | 06-02-2011 |
| 20110240525 | Distillation Column Pressure Control - Methods and systems for controlling the pressure of distillation columns, for example those operating under vacuum pressure and conventionally equipped with a steam ejector system, are described. Representative distillation columns are used in the separation of thermally unstable components, such as the physical solvent sulfolane, having relatively low volatility. Such columns are employed in aromatic hydrocarbon extraction processes for the recovery of purified C | 10-06-2011 |
| 20130153470 | EXTRACTION OF POLYCYCLIC AROMATIC COMPOUNDS FROM PETROLEUM FEEDSTOCKS USING IONIC LIQUIDS - The present invention involves a process for removing one or more polycyclic aromatic hydrocarbon compounds from a vacuum gas oil comprising contacting the vacuum gas oil with a vacuum gas oil-immiscible phosphonium ionic liquid to produce a mixture comprising the vacuum gas oil and the vacuum gas oil-immiscible phosphonium ionic liquid; and separating the mixture to produce a vacuum gas oil effluent and a vacuum gas oil-immiscible phosphonium ionic liquid effluent, the vacuum gas oil-immiscible phosphonium ionic liquid effluent comprising the polycyclic aromatic hydrocarbon compound. | 06-20-2013 |
| 20130175204 | METHOD FOR REDUCING CATALYST FINES IN SLURRY OIL FROM A FLUIDIZED CATALYST CRACKING PROCESS - A composition useful for reducing catalyst fines in an FCC slurry oil from a fluid catalytic cracking process is disclosed wherein the composition comprises a first resin which is an nonyl-phenol formaldehyde resin that has been ethoxylated and a second resin which is a p-t-amyl-phenol formaldehyde resin that has been ethoxylated. | 07-11-2013 |
| 20130306523 | METHOD FOR DEWAXING MINERAL OIL COMPOSITIONS - The present invention relates to a lubricant composition for a process for reducing the paraffin content of mineral oil compositions, by providing a mineral oil composition with a dewaxing aid, cooling to form a paraffin precipitate and at least partly removing the paraffin precipitate formed. The dewaxing aid used is a copolymer mixture comprising at least three copolymers, the copolymers differing in the composition of the repeat units. | 11-21-2013 |
| 20140183102 | Additive and Method for Removal of Calcium from Crude Oils Containing Calcium Naphthenate - There is provided an additive and method for removal of calcium from crude oil or its blends containing calcium naphthenate at low pH as well as at high pH varying from 5 to 11, preferably from 6 to 11, more preferably from 7 to 11, wherein the additive is glyoxal and said pH is of the wash water for crude oil processing systems. | 07-03-2014 |
| 20140262957 | EVALUATION OF DISTILLATE COMPOSITION OF A CRUDE - Methods are provided for characterizing crude oils, crude fractions, or other potential feedstocks for forming lubricating base oils in order to determine the suitability of a feedstock for lubricating base oil production. One type of characterization is to determine the isoparaffin, naphthene, and/or aromatics contents of the distillate portion of a feedstock. A second characterization is to determine the viscosity index of a distillate portion of a feedstock after dewaxing the distillate portion to a target pour point. | 09-18-2014 |
