Experiments on the dissolution of asphalt-resin-paraffin deposits (ARPD) by individual, double and ternary solvents were performed. All solvents components are low-value by-products of different productions of JSC «ANHK». A mathematical model was derived on experimental results and let to find the optimal recipe of solvent with maximum washing and dissolving abilities for ARPD.
