SURGE-VESSEL - SEPARATOR Russian patent published in 2015 - IPC B01D19/00 E21B43/34 

FIELD: oil and gas industry.

SUBSTANCE: surge-vessel - separator comprises the main vertical vortex cyclone with tangential admission of gas-fluid mixture, auger-type turbulence chamber, the central pipeline for gas extraction and a tank for liquid collection, which is located under the cyclone. The lower part of the liquid-collecting tank is connected to the pipeline for liquid drainage. The surge-vessel - separator comprises auxiliary vertical vortex cyclone, which body is placed with a gap inside the central pipeline for discharge of gas from the main cyclone, in which upper part there are openings interconnected with input chamber of the auxiliary vortex cyclone. Under input chamber of the auxiliary vortex cyclone there is a turbulence chamber and central pipeline for gas output. The tank for collection of liquid from the auxiliary cyclone is placed in the tank for collection of liquid from the main cyclone and is connected to it.

EFFECT: improved efficiency of gas separation from liquid and reduced hydraulic fluctuation at transportation of oil well products through pipelines and at measuring yield of the well.
