The article is devoted to the results of the study of the component composition of the vacuum residue of oil from the deep-water Guneshli field, which is produced in the Caspian sector from a depth of 3000–4000 m. The oil is light, low-sulfur, paraffinic (3.7 % solid paraffins), contains a small amount of heteroatoms, without asphaltenes.
The vacuum residue (>450 oC) was separated into naphthene-paraffin, aromatic and resin components with the method of column liquid eluent-adsorption chromatography. The structural group composition of individual groups was studied using IR and PMR spectroscopy. As a result, it was found that even concentrates of aromatic hydrocarbons and resins isolated from the residue (>450 oC) are enriched with naphthenic structures, the most valuable compounds that are part of oils and fuels, providing them with high performance properties.
