The gas-liquid separator having an introduction duct defining an introduction opening receiving the multiphase fluid stream, and a static first separation stage extending along a longitudinal axis, connected with the introduction duct, the first separation stage including an outer wall, an inner wall and at least an inner baffle inducing an helical movement of the multiphase fluid stream around the longitudinal axis driving a liquid contained in the fluid stream onto the outer wall and a gas contained in the multiphase fluid stream onto the inner wall. The outer wall or/and the inner wall delimit(s) at least a lateral orifice evacuating a respective one of the liquid or the gas separated along the inner baffle, each lateral orifice extending along each inner baffle and defining a lateral staged evacuation of the respective one of the liquid or of the gas in an evacuation canal along the respective inner and outer walls.

Gas-liquid separator, hydrocarbon extractor, and related separation method

The present invention concerns a system for extracting the liquids from a well producing liquid and gas. The system comprises a separation wall defining, in the well, a first space and a second space; a liquid-gas separator; and a system for eliminating separated liquid. The first space is suitable for conveying a mixture comprising the gas and liquid from a production area to the separator. The separator is suitable for separating the gas and liquid from the mixture. The second space receives the liquid separated from the mixture. Finally, the elimination system is suitable for eliminating the separated liquid using at least the gravitational potential energy of said separated liquid in the second space.
