FIELD: mechanical engineering; internal combustion engines.

SUBSTANCE: invention relates to methods of changing main physical properties of liquid hydrocarbons. According to proposed method pulsations are excited in moving liquid flow at provision of amplitudes of pressure, velocity and acceleration fluctuations contributing to breaking of drops and bubbles in continuous flow of liquid. First molecules of hydrocarbons are polarized by passing through electromagnetic field of 0.2-0.3 T. Then macromolecules and colloids are subjected to resonance vibration of 20-30 Hz to increase amplitude of fluctuation. Pressure is raised by pump to 6.0-8.0 MPa at inlet of converging and diverging device where fuel is accelerated up to 120-140 m/s with subsequent braking to obtain pressure of 0.02-0.01 MPa. Then flow is divided into light and heavy fractions in Rank tube. Light fractions are directed for storage or combustion after polarization of molecules in electromagnetic field. Heavy hot fractions in amount of 10-15% of total flow are returned by pipeline into reservoir with initial fuel for repeated processing. Device for improving physical properties of oil products contains electromagnetic device for polarizing molecules connected by pipe with reservoir which accommodates vibrator with vibration frequency electric generator, pump to increase liquid flow pressure before inlet of converging and diverging device providing flow out of liquid fuel at speed of 120-140 m/s, Rank tube for dividing processed fuel flow into light and heavy fractions. Light fractions are passed through electromagnetic device and are directed either for storage or to nozzles for combustion. Heavy hydrocarbons are directed along pipe to initial fuel reservoir for repeated processing.

EFFECT: improved physical properties of liquid oil field.
