FIELD: oil and gas industry.
SUBSTANCE: invention refers to a method for obtaining waxy winter grades of fuels by dewaxing of oil products by mixing of raw material with a surface active substance, cooling to dewaxing temperature with further extraction of paraffin hydrocarbons in a constant electric field. As an auxiliary surface active substance, low-mineralised water is used with salt content of up to 500 mg/l in the form of a water-alcohol solution chosen from C1-C5 alcohols in the ratio of 100:1.
EFFECT: improvement of low-temperature fuel properties.
