“…[4][5][6] In SARA fractionation, asphaltenes are first precipitated using n-alkanes, such as n-pentane or nheptane. 4,7 After removal of asphaltenes, the remaining SARA fractions are sequentially obtained by eluting the remaining components, collectively called maltenes.…”

SARA fractionation separates the oil into fractions of saturates (S), aromatics (A), resins (R), and asphaltenes (A) based on the differences in their polarizability and polarity.Defined as a solubility class, asphaltenes are normally considered as a menace in the petroleum industry mainly due to their problematic precipitation and adsorption at oil water and oil-solid interfaces. As a broad range of molecules fall within the group of asphaltenes with distinct sizes and structures, considering the asphaltenes as a whole was noted to limit the deep understanding of governing mechanisms in asphaltene-induced problems.Extended-SARA (E-SARA) is being proposed as a concept of asphaltene fractionation according to their interfacial activities and adsorption characteristics, providing critical information to correlate specific functional groups with certain characteristics of asphaltene aggregation, precipitation and adsorption. Such knowledge obtained is essential to addressing asphaltene-related problems by targeting specific subfractions of asphaltenes for selective removal.2

“…[22][23][24][25][26][27]) could be adapted for acid tars. Liu et al [28] used a saturates, aromatic, resin, and asphaltene (SARA) separation technique [29] to analyse coal tar from the pyrolysis of coal asphaltenes. Saturates and aromatics from this separation were further separated into individual organic compounds using gas chromatography.…”

“…The separation of a residual oil into paraffins, non-polar aromatics, resins and asphaltenes is a common practice in petroleum engineering (Jewell et al, 1974). Following this separation these compound-class fractions are analysed using (for instance) "C or 'H n.m.r.…”
