FIELD: oil and gas industry.
SUBSTANCE: invention is related to gas producing and processing industry and may be used, in particular, for processing of paraffin dehydrated and desalinised oil in order to improve its solidifying characteristics and namely setting point and relaxation time increment for this parameter. Dehydrated and desalinised raw stock in continuous flow mode with the flow rate of 0.2-1.2 m/s is treated by ultrasound with frequency of 25-65 kHz and by permanent magnetic field with inductance of 0.05-0.5 T.
EFFECT: stable improvement of oil solidifying characteristics, reduction of time for its processing.
