METHOD FOR SEPARATION OF GAS-LIQUID MIXTURE AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2018 - IPC B01D17/04 B01D19/00 

FIELD: oil and gas industry.

SUBSTANCE: device for separation of water-oil emulsion contains a body (1), a batcher of mixture constant flow rate (8) installed at the inlet, an inlet pipe union (2) communicating with a mixture supply chamber (15), drain shelves (6) with alternating matching holes (17), unions (3, 4, 5) of gas, oil and water discharge with the drain shelves (6) attached to a shaft (14) driven by a drive (11) and a transmission (12). The emulsion is supplied at constant flow rate through pressure pipeline (7) via the feed chamber (15) into a gap between the two surfaces of the drain shelves (6). To create critical resonance thickness of emulsion boundary layer, one of the surfaces receives reciprocal or torsional vibrations. The mixture is subjected to shear stress by mutually opposite reciprocal motion of the drain shelves (6) parallel relatively each other. When passing through holes (17) of the drain shelves 6, emulsion acquires pulsating motion generating acoustic vibrations therein. The outlet flow rate between the drain shelves (6) should not exceed critical rate of cavitation development.

EFFECT: increased efficiency of dewatering and desalting of water-oil emulsion.
