Abstract: The process of the asphaltene-resin-paraffin deposits (ARPD) dissolution in the hexane-benzene mixture at 10–60 ${}^\circ$C is investigated. The kinetic description of process is performed by Erofeev–Kolmogorov equation. The kinetic parameters: rate constant, activation energy, and reaction order of ARPD dissolution are estimated. The possibility of the kinetic parameters usage for evaluation of the solvent effectiveness to remove deposits is shown.

Keywords: asphaltene-resin-paraffin deposits, paraffin type, aliphatic-aromatic solvents, reaction order, rate constant.
