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: A method includes introducing a crude oil process stream into an electro-kinetic separator (EKS), passing the crude oil process stream through an electric field generated by the EKS, and removing at least a portion of salt and solid particles from the crude oil process stream as the crude oil process stream passes through the electric field. A product stream is discharged from the EKS with reduced salt and solid particle count as compared to the crude oil process stream.

Abstract: Systems and methods are provided for using field enhanced separations to produce multiple fractions from a petroleum input. A liquid thermal diffusion and/or electric field separation is used to produce the fractions. The fractions can then be used to form multiple outputs that share a first feature while being different with regard to a second feature. For example, a first fraction from the plurality of fractions can have a desired value for a first property such as viscosity index. Two or more additional fractions from the plurality of fractions can then be blended together to make a blended fraction or output. The blended fraction can have a value for the first property that is substantially similar to the value for the first fraction. However, for a second property, the first fraction and the blended fraction can have distinct values. As a result, multiple output fractions can be formed that share a first feature but differ in a second feature.

Abstract: An electro-kinetic agglomerator for resolving crude oil and water emulsions containing charged particles by the application of a direct current voltage potential. The electro-kinetic agglomerator comprises a shaftless auger with a charged conductive rod positioned in the center of the shaftless auger and a charged porous drum surrounding wherein the electro-kinetic agglomerator has a DC voltage gradient such that the charged particles are attracted to the conductive rod.
