DEVICE FOR SELECTING HYDROCARBON LIQUID WITHOUT RELEASE OF GAS TO ATMOSPHERE Russian patent published in 2021 - IPC E21B49/00 G01N1/10 

FIELD: gas production.

SUBSTANCE: invention relates to the gas production industry, in particular to a method for sampling the liquid phase at the mouth of gas condensate wells without releasing hydrocarbon gas into the atmosphere. The device contains a droplet separator placed in a container with water cooled to the crystallization temperature, which is mounted on an instrument flange located between the working and control string valves, in front of the corner fitting of the wellhead fountain tree; pressure gauges are installed on three-way taps located in front of the droplet separator and at the entrance to the process line; the outlet of the high pressure pipe is mounted behind the corner fitting.

EFFECT: invention allows carrying out sampling with obtaining the necessary data on the qualitative composition of the gas-liquid mixture without additional installation work in the piping of the well and the fountain tree and reduces the sampling time.
