METHOD OF OIL REFINING AND OIL REFINING PLANT FOR REALIZATION OF THIS METHOD Russian patent published in 2000 - IPC

FIELD: petroleum chemistry; methods of refining oil by means of rectification units. SUBSTANCE: part of oil is fed to additional liquid-and-gas jet apparatus which is used for discharging gaseous medium from separator of vacuum hydrocirculating unit creating vacuum in separator; mixture obtained in additional liquid-and-gas jet apparatus is fed together with oil to oil refining section under excessive or atmospheric pressure. As far as oil refining is concerned, plant is provided with additional liquid-and-gas jet apparatus connected to oil supply main on side of liquid inlet and to separator gaseous medium outlet on side of gas supply; mixture outlet is connected to oil supply main; working fluid delivery pump of vacuum hydrocirculating unit is connected to separator working liquid outlet on side of inlet. EFFECT: ecologically pure system; low power requirements for creating and maintaining vacuum; complete avoidance of loss of hydrocarbon material. 9 cl, 1 dwg
