FIELD: oil and gas industry.
SUBSTANCE: invention relates to the method for preparing high viscosity oil for transporting it through a pipeline. Method involves mixing high viscosity oil with an additive, then thermocracking the resulting mixture and separating the thermocracking products into gas vapor and liquid phases. In this case, the bottom residues of ethylbenzene distillation are used as an additive in the amount of 2–4 % by weight per raw material, and the target product – heat-treated oil is obtained by means of mixing the liquid phase of thermocracking and the stable light distillate of a gas-vapor-liquid mixture of thermocracking products.
EFFECT: method for preparing high-viscosity oil for its transportation through a pipeline is proposed.
