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 and oil refining industry, particularly to destruction of water-oil emulsions. Proposed is a device for destruction of water-oil emulsion at transportation through a pipeline including a pipeline and a longitudinal partition made in the form of a rectangular plate smoothly coiled along a spiral, herewith its edge at the outlet is turned at 180° relative to the edge at the inlet. Pipeline before the longitudinal partition in the direction of the water-oil emulsion flow is equipped first with a converging cone, and then with an expanding cone with the possibility of separate longitudinal movement and fixation relative to the pipeline, herewith the converging cone outside is equipped with a spiral plate with the turning angle along the length of the converging cone of 90° at the ratio of through circular cross section of bases squares at the inlet and the outlet of the cone of 3:1 in the direction of the water-oil emulsion flow and the length of the converging cone to its maximum inlet diameter at the ratio of 4:1, herewith the expanding cone inside is equipped with a spiral plate with the turning angle along the length of the expanding cone of 90° at the ratio of squares at the inlet and outlet of the cone bases of 1:3 in the direction of the water-oil emulsion flow and the length of the expanding cone to its maximum inlet diameter at the ratio of 1:4, herewith in the pipeline after the converging and the expanding cones there are radial holes connected to a branch pipe with a gate valve embedded into the pipeline for removal of heavy fractions.

EFFECT: device increases efficiency of oil-water emulsion destruction, provides faster destruction of the oil-water emulsion, improves reliability of the device operation and reduces costs for desalination and dehydration of oil after transportation.
