METHOD OF ENGINE OIL PURIFICATION

FIELD: petroleum processing. SUBSTANCE: to remove water and suspended impurities, oil warmed to 65- 70 C is treated on centrifugal separator at atmosphere pressure, after which temperature is raised to 90-100 C and then lowered to 65-70 C. In final treatment stage, oil is repeatedly centrifuged unde...

Zusammenfassung:	FIELD: petroleum processing. SUBSTANCE: to remove water and suspended impurities, oil warmed to 65- 70 C is treated on centrifugal separator at atmosphere pressure, after which temperature is raised to 90-100 C and then lowered to 65-70 C. In final treatment stage, oil is repeatedly centrifuged under vacuum. EFFECT: reduced content of water to not higher than three hundredth percent.
