METHOD OF CLEANING VAPOR-GAS MIXTURE FORMED AT FILLING CONTAINER WITH OIL PRODUCT FROM VAPORS Russian patent published in 2002 - IPC

Abstract RU 2193001 C1

FIELD: jet facilities. SUBSTANCE: methods of cleaning vapor-gas mixture from VAPORS of oil product comes to delivery of liquid medium into liquid-gas jet apparatus, pumping out of vapor-gas mixture and its compression in jet apparatus, delivery of two-phase mixture formed in jet apparatus into separator and separation of two-phase mixture in separator into gaseous phase and liquid phase, delivering of liquid medium from separator to pump input and bringing part of liquid medium from circulation circuit. Gaseous phase is directed from separator into absorption tower into which hydrocarbon containing liquid is fed with saturated vapor pressure less than pressure of saturated vapors of oil product. Vapors of oil product from gaseous phase are absorbed by hydrocarbon containing liquid in absorption tower. Gaseous phase cleaned from vapors of oil product is brought out of absorption tower, and hydrocarbon containing liquid with dissolved VAPORS of oil product is directed into liquid medium circulation circuit. As a result, cleaning of vapor-gas mixture from vapors of oil product formed at filling of container with oil product is improved with bringing the level of concentration of vapors in surrounding medium below tolerable value. EFFECT: reduced losses of oil and oil product caused by evaporation. 3 cl, 2 dwg
