Abstract: Systems and methods are provided for integration of use deasphalted resid as a feed for fuels and/or lubricant base stock production with use of the corresponding deasphalter rock for gasification to generate hydrogen and/or fuel for the fuels and/or lubricant production process. The integration can include using hydrogen generated during gasification as a fuel to provide heat for solvent processing and/or using the hydrogen for hydroprocessing of deasphalted oil.

Abstract: Systems and methods are provided for using a three-product deasphalter to produce advantageous combinations of deasphalted oil, resin, and rock. The desaphalted oil, resin, and rock can then be further combined, optionally with other vacuum gas oil fractions produced during the distillation that generated the feed to the three-product deasphalter, to produce a product slate of improved quality while also maintaining the quality of the resulting asphalt product and reducing or minimizing the amount of lower value products generated. The additional “resin” product from the three product deasphalter can be generated by sequential deasphalting, by using a resin settler to separate resin from the deasphalted oil, or by any other convenient method.

Abstract: Compositions are provided for lubricant base stocks produced from feeds such as vacuum resid or other 510° C.+ feeds. A feed can be deasphalted and then catalytically and/or solvent processed to form lubricant base stocks, including bright stocks that are resistant to haze formation.

Abstract: Deasphalter rock from high lift deasphalting can be combined with a flux to form a fuel oil blending component. The high lift deasphalting can correspond to solvent deasphalting to produce a yield of deasphalted oil of at least 50 wt %, or at least 65 wt %, or at least 75 wt %. The feed used for the solvent deasphalting can be a resid-containing feed. The resulting fuel oil blendstock made by fluxing of high lift deasphalter rock can have unexpectedly beneficial properties when used as a blendstock.

Abstract: Systems and methods are provided to allow for characterization of feeds, intermediate effluents, and/or products during lubricant base stock production. More generally, the systems and methods can allow for characterization of aromatics in various types of hydroprocessed intermediate effluents and/or products. In some aspects, the characterization can include measuring a fluorescence excitation-emission matrix spectrum for a sample, and then generating a representation of the spectrum by fitting the measured spectrum to a linear combination of spectra corresponding to compounds or compound classes. As the hydroprocessing process continues, additional measured spectra and comparing the fit quality of the representation to the subsequently measured spectra. When the fit quality falls below a threshold value, the loss in fit quality indicates a change in the number and/or distribution of aromatics in the sample. In other aspects, fluorescence excitation-emission spectroscopy can be used to characterize the amount of aromatics within a sample that correspond to one or more fluorescence compound classes. Based on this characterization, adjustments can be made to a process to reduce undesirable levels of aromatics, such as undesirable levels of polynuclear aromatics.

Abstract: Systems and methods are provided for block operation during lubricant and/or fuels production from deasphalted oil. During “block” operation, a deasphalted oil and/or the hydroprocessed effluent from an initial processing stage can be split into a plurality of fractions. The fractions can correspond, for example, to feed fractions suitable for forming a light neutral fraction, a heavy neutral fraction, and a bright stock fraction, or the plurality of fractions can correspond to any other convenient split into separate fractions. The plurality of separate fractions can then be processed separately in the process train (or in the sweet portion of the process train) for forming fuels and/or lubricant base stocks. This can allow for formation of unexpected base stock compositions.
