DEVICE FOR DESTRUCTION OF WATER-OIL EMULSION DURING TRANSPORTATION THROUGH PIPELINE Russian patent published in 2016 - IPC C10G33/06 B01D17/04 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to oil extraction and oil refining industry, particularly to breakdown of water-oil emulsions. Device for breaking down a water-oil emulsion during transportation through a pipeline comprises a pipeline and a longitudinal partition made in form of rectangular plate, smoothly coiled along a spiral, wherein its edge at outlet is turned 180° relative to edge at inlet. Pipeline before longitudinal partition in direction of flow of water-oil emulsion is equipped with a cone, converging in direction of flow of water-oil emulsion at a ratio of areas of bases of cone of 2:1 in direction of flow of water-oil emulsion, wherein inside cone there is a concentrically fitted auger made in form of a spiral plate, wherein flow section area of auger decreases in axial direction from inlet to outlet, and inclination angle of spiral plate of auger at outlet is less than 90°, wherein at outlet of cone between auger and cone there is an annular disc, together with cone forming an annular chamber, hydraulically communicated via a radial hole made in cone with removal of heavy fractions, embedded into pipeline, wherein flow section area between auger and annular disc is smaller than that at output of auger.

EFFECT: proposed device for breaking down water-oil emulsion during transportation through pipeline increases efficiency of breaking down oil-water emulsion; speeds up process of breaking down oil-water emulsion; improves reliability and reduces costs on desalination and dehydration of oil after transportation.
