FIELD: oil and gas industry.
SUBSTANCE: invention can be used in oil industry. Initial raw material is heated in tube furnace 2 up to 400 °C by supplying water condensate to the inlet part of coil of the tube furnace. Heated raw material is mixed with recirculated substance and light fractions are separated in evaporator 3 so that secondary raw material is formed. Secondary raw material is heated in reaction tube furnace 4 with its further being coked in coking chambers 5 so that coke and distillate products are obtained. Mixture of light fractions obtained in evaporator and distillate coking products are separated in rectifying column 6 into vapour products, light and heavy gas oils and residual oil.
EFFECT: invention allows reducing coking of coils of tube furnace for heating of initial coking raw material with simultaneous increase of efficiency of coke obtaining method.
