METHOD OF SEPARATION OF AN OIL-WATER EMULSION Russian patent published in 2005 - IPC

FIELD: oil-producing industry; methods of field separation of mixture of oil.

SUBSTANCE: the invention is pertaining to the field of separation of petroleum, sub-finished water product and an accompanying gas. The method of separation of the oil-water emulsion into phases is realized by conducting all the operations of separation in one apparatus by means of centrifugal forces, which are used in a direction of their action in the dual-drum whizzer with the rhomboidal drums of different diameter. Preliminary separation of the oil-water emulsion into water, petroleum and a gas is conducted in a tube-axis and in the drum of the greater diameter, and the final separation of the liquid and the gaseous phases into oil and a gas is conducted in the drum of the smaller diameter and also under action of centrifugal force. Feeding of so procured oil-water emulsion for separation and withdrawal of the gaseous products is conducted through the central tube-axis of the whizzer continuously and under a heightened pressure. The water and oil remove from the whizzer through the circle branch-pipes located around the motionless containers occluding the movable drums of the whizzer. The technical result is an increased effectiveness of separation.

EFFECT: the invention ensures an increased effectiveness of separation.
