The supercritical fluid extraction method allows petroleum refiners to produce high-value vacuum gas oil. Petroleum refiners can separate bottom-of-the-barrel petroleum residua into 20 narrow subfractions related to the fraction's molecular weight. This method helps petroleum refiners better understand the chemistry of the feedstock. Other methods used in heavy petroleum feedstock fractioning include sequential extraction fractionation and conventional vacuum distillation., The ability to process bottom-of-the-barrel fractions is strongly dependent on the chemistry of the feedstocks. But, because of the complexity of residue species there is no standard analytical tool or [...]
