FIELD: oil and gas industry.SUBSTANCE: invention refers to oil processing industry, and namely to oil refining, and can be used for its separation into fractions. The invention refers to the oil refining method and consists in its being pre-heated up to the specified temperature, further separation in adiabatic separator into vapour and liquid phases and supply of the heated agent to the separator bottom to reduce the refining temperature; as the agent, there used is methane-containing hydrocarbon gas (MHG) heated up to 380-400°C and containing 90-95 mol % of methane in quantity of 0.5-3.0 wt %; vapour phase containing low-boiling components of oil and methane-containing hydrocarbon gas is separated for oil at the pressure of 0.5-0.6 MPa and condensed; methane-containing hydrocarbon gas is extracted, heated up to the specified temperature and returned to the process.EFFECT: reduction of energy consumption for preparation of agent for oil refining temperature reduction.1 tbl, 5 ex |
