Abstract

The sedimentation in high-paraffin oil with the addition of different resins and an inhibiting additive was studied. It was found that the amount of oil sediment decreased with an increase in the concentration of resins in oil with a lower surface tension and a large number of heteroatomic components. With an increase in the fraction of resins with a higher content of polysubstituted aromatic structures, an increase in the amount of oil sediment and a decrease in the efficiency of the inhibiting additive were observed. With an increase in the amount of oil resin additives, the fraction of low-molecular-weight n-alkanes in the composition of asphalt–resin–paraffin deposits (ARPD) decreased and the average sizes of paraffin hydrocarbon aggregates decreased.
