20080223751 | Non Asphaltenic Oil - A reconstituted non-asphaltenic oil Pa comprising at least 28% by weight of naphtha N, having a ratio R of 1.5 or more and a gasoline potential, POTg, in the range 47 to 70, in which: R=(0.9 N+0.5 VGO+)/(MD+0.1 VGO+), POTg=0.9N+0.5 VGO+, with in % by weight: N=naphtha: [30° C./170° C.]; MD=middle distillates: ]170° C./360° C.] and VGO+=fraction boiling above 360° C. | 09-18-2008 |
20080289999 | Process for Pre-Refining Crude Oil with Moderate Multi-Step Hydroconversion of Virgin Asphalt in the Presence of Diluent - For pre-refining a crude oil P, which P is fractionated into several fractions, typically hydrotreating, hydrocracking or hydroconverting some thereof, then re-composing said fractions and in general producing at least two pre-refined oils Pa, Pc, Pa being a high quality non-asphaltenic oil and Pc being a residual oil. The process typically comprises at least one initial distillation step and one deasphalting step SDA with a solvent with a molecular weight of at least 50 to separate a deasphalted oil DAO from a virgin asphalt stream AS. AS is hydroconverted in at least 2 ebullated bed reactors in series, with a moderate conversion of less than 56%, mixed with a virgin diluent comprising light fractions. The DAO is typically hydrocracked with a limited conversion of less than 80%. | 11-27-2008 |
20090308788 | PROCESS FOR PRE-REFINING CRUDE OIL FOR THE PRODUCTION OF AT LEAST TWO NON-ASPHALTENIC OILS Pa, Pb, AND AN ASPHALTENIC OIL Pc - A process for pre-refining a crude oil P is described in which P is fractionated into several fractions, some of which are typically hydrotreated, hydrocracked or hydroconverted, then said fractions are re-composed and at least three pre-refined oils Pa, Pb, Pc are produced, Pc being a residual asphaltenic oil and Pa and Pb being two non asphaltenic oils having different ratios R wherein: | 12-17-2009 |
20100276334 | PROCESS FOR CONVERTING GAS INTO LIQUIDS WITH SIMPLIFIED LOGISTICS - The invention concerns a process for converting a stream of natural or associated gas into liquid fractions, comprising:
