FIELD: chemistry.
SUBSTANCE: invention refers to methods for processing liquid raw hydrocarbons for gasoline fraction and low-boiling oil solvents and can be applied particularly in processing of base oil, gas condensate or industrial low-boiling hydrocarbon waste, e.g. of gathered oil spill on water or earth. In method for liquid raw hydrocarbons involving isothermal distillation and condensation of light fractions, liquid raw hydrocarbons of temperature 10-80°C is introduced into the reactor occasionally at atmospheric pressure. Every cycle starts with unproductive decompression in the reactor to 500 torr. Thereafter vacuum distillation of raw hydrocarbons follows to separate liquid phase of dissolved hydrocarbons noncondensing under existing conditions, and light fractions by controlled decompression in the reactor to 5 torr with the following condensation of the separated light fractions at temperature 10-30°C and gas hydrocarbon withdrawal.
EFFECT: there is improved method for processing liquid raw hydrocarbons for gasoline fraction.
