FIELD: petroleum processing. SUBSTANCE: petroleum is first pumped into liquid-gas jet apparatus, from which gaseous hydrocarbons entering through gas inlet connected to low- pressure gas line are pumped out. In jet apparatus, low-pressure gas is compressed loosing a part of hydrocarbons dissolved in petroleum, which gives rise to creation of gas-liquid mixture. The latter is fed into separator wherein compressed gas is separated from petroleum with dissolved therein hydrocarbons. Separated compressed gas is directed to consumers and petroleum with dissolved hydrocarbons is heated and fed into rectification column. EFFECT: reduced operational expenses. 4 cl, 1 dwg
