The results of research on dissolution kinetics of petroleum paraffins and asphaltene-resin-paraffin deposits (ARPD) of the paraffin type in aliphatic, aliphatic-aromatic, and aliphatic-naphthenic-aromatic systems within the temperature range from 10 to 60° C have been discussed. The half-life periods, order of reactions, dissolution rate constants and activiation energy of destruction of paraffins and ARPD have been calculated. Differential scanning calorimetry has been used to study the phase transitions of petroleum and commercial paraffins in aliphatic and mixed hydrocarbon solvents. Based on the conducted research, recommendations for selection of an effective solvent to remove paraffin deposits at low temperatures of reservoirs have been proposed.
