FIELD: oil and gas industry.SUBSTANCE: invention relates to the method of rectification of hydrocarbon mixes comprising the adding of methane containing gas to the hydrocarbon mix, heating and supply of the obtained mix into the supply section of the rectifying column. The methane containing gas is mixed with the hydrocarbon mix using the ejection method, while from the cube of the rectifying column the residue is separated a part of which, used as a hot flow, is mixed with the methane containing gas using the ejection method and the mix from the ejector is heated and supplied into the cube of the rectifying column.EFFECT: improvement of the process of hydrocarbon mix rectification due to decrease of content of low-boiling components in diesel fraction.1 tbl, 1 ex |
