GAS-LIQUID SEPARATOR Russian patent published in 2011 - IPC B01D19/00 

FIELD: oil and gas industry.

SUBSTANCE: separator includes housing made in the form of outer cylinder 1, inner cylinder 2 located in it and having gas outlet holes 7 and spiral element 3 with helical surface, which is installed between them and forms a spiral channel. In upper part of outer cylinder 1 there is gas-liquid mixture supply device 4, and in lower part there is liquid discharge device 6. Inner and outer diameters and pitch of helical surface have been chosen from condition which provides gravity flow of gas-liquid mixture, at which hydraulic losses are less than hydrostatic pressure rise.

EFFECT: higher efficiency of extraction of gas inclusions from liquid.
