OIL STOCK DISTILLATION PROCESS Russian patent published in 1999 - IPC

Abstract RU 2137803 C1

FIELD: petroleum processing. SUBSTANCE: when distilling oil stock on atmospheric rectification column, gas-vapor phase condensate from condenser is fed into reservoir from which cooled condensate is forced as ejection medium into the nozzle of liquid-gas jet apparatus by means of which pressure in the above-mentioned reservoir is maintained from 0.06 to 0.28 MPa. Top vapor outlet pressure is maintained from 0.07 to 0.30 MPa. Pressure in reservoir is used to feed condensate leaving jet apparatus into the top of column as phlegm. EFFECT: increased rectification efficiency, increased processing completeness, and reduced power consumption. 5 cl, 1 dwg
