FIELD: oil and gas industry.
SUBSTANCE: method includes heating of a raw material to 450-490°C in coil of furnace, supply of heated raw material to reaction chamber, and division of viscosity breaking products in a rectifying column into distillate, gas-oil fractions and residue. Between the reaction chamber and the successive assembly there exists pressure drop created by means of reducing valve or gate, installed after the reaction chamber at helmet pipeline which is adjusted depending on the colour of gas-oil fractions.
EFFECT: facilitating controlled quality of received gas-oil fractions at simplified process.
