FIELD: oil and gas industry.
SUBSTANCE: invention refers to chemical technology and oil and gas processing and can be implemented for oil products de-waxing and for extracting paraffin hydrocarbon out of them; purpose of invention is increased withdrawal of de-waxed diesel fuel at maintaining indices of low temperature properties of diesel fuel - setting and cloud points. The method of de-waxing of oil products is performed by mixing raw stock with a surface-active substance, by heat treatment of obtained mixture, and by cooling it to the temperature of de-waxing with successive extraction of paraffin hydrocarbons in electrostatic field. A product of interaction of stearic acid, polyethylenpolyamines and formaladehyde at weight ratio correspondingly 4.5:1.0:2.0 is used as a surface-active substance.
EFFECT: extraction of paraffin hydrocarbons out of oil products at increased output of de-waxed diesel fuel at maintaining indices of low-temperature properties of diesel fuel - setting and cloud points.
