WATER-IN-OIL EMULSION SEPARATION METHOD USING ULTRASONIC EXPOSURE Russian patent published in 2015 - IPC B01D17/04 C02F1/36 C10G33/00

Abstract RU 2568980 C2

FIELD: oil and gas industry.

SUBSTANCE: invention may be used in oil industry for the purpose of oil dehydration. Water-in-oil emulsion separation method using ultrasonic exposure includes treatment of emulsion with ultrasound, at that optimal ultrasonic frequencies are pre-determined depending on size of water drops in emulsion that allow minimum water share in oil. Emulsion treatment is carried out with change in optimal ultrasonic frequency depending on change in size of water drops in the process of treatment.

EFFECT: invention allows increase in oil dehydration degree and reduction of settling time thus allowing reduced capital costs for oil dehydration.
