LIQUID-GAS SEPARATOR Russian patent published in 2016 - IPC B01D19/00 B01D17/28 E21B43/34 

FIELD: technological processes.

SUBSTANCE: invention relates to separators for separation of liquid media with different specific weight and for separation of accumulated in the liquid gaseous medium. Separator comprises a housing, a vertical partition wall, a gas-liquid mix feed pipeline, branch pipes to discharge the gaseous medium, heavier and lighter fractions of the liquid medium, a package of phase-separating nozzles, an overflow partition and a drain chute, which is connected with its upper edge to the upper edge of the vertical partition wall and with its lower edge - to the package of phase-separating nozzles on the side of its inlet, all attached to a transverse partition passing heavier fraction of the liquid medium from below and the gas from above. Liquid medium heavier fraction discharge branch pipe is connected with the housing lower part between the vertical partition wall and the overflow partition, a the liquid medium lighter fraction discharge branch pipe is equipped with a controlled shutter and is introduced into the housing below the level of the liquid medium. Gas-liquid mix feed pipeline is introduced into a vertical hydraulic cyclone tightly introduced into the housing and equipped with a concentrically installed deentrainment chamber, the inner space of which above the level of the liquid is connected with the gaseous medium discharge branch pipe additionally connected with a tube to a space under the drain chute above the level of the liquid. In the inlet section of the housing concentrically between the hydraulic cyclone and the deentrainment chamber there are separation elements made in the form of two short pipes and located between them one long pipe. Lower edges of the short pipes are located above the liquid level in the housing, and the lower edge of the long pipe is located below the liquid level in the housing. From above between the short pipes there is a gas vent channel connected with the gaseous medium discharge branch pipe. Deentrainment chamber inside is equipped with an inertial deentrainment device in the form of inclined downward truncated cones. At the inlet of the gaseous medium discharge branch pipe there is a screen consisting of mutually facing each other at the bottom a tapering upward cone while at the top a truncated cone diverging from bottom to top. Above the gas vent channel the gaseous medium discharge branch pipe is equipped with a vertical metal mesh. In the outlet section of the housing there is the second vertical partition wall, and between the transverse partition and the second vertical partition wall there is a package of phase-separating nozzles. Under the package of phase-separating nozzles above the overflow partition concentrically to the housing there is a pipe with through holes, herewith one end of the pipe is plugged with the transverse partition, and at the other end the pipe inner space is connected with a pocket rigidly secured to the second partition wall. Pocket behind the second vertical partition wall in the outlet section is hydraulically connected with the liquid medium lighter fraction discharge branch pipe. Tube connected with the gaseous medium discharge branch pipe inside the housing is equipped with a gas feed branch pipe from the separator housing.

EFFECT: higher efficiency of extracting gas from a gas-liquid mix, excluding penetration of heavy fraction of the liquid medium into the liquid medium lighter fraction discharge branch pipe.
