Sample capture system and methods of use

摘要

Disclosed herein is a sampling system for obtaining a representative fluid sample from a high pressure multiphase multicomponent fluid, the system comprising: a fluid flow path for transmitting the high pressure multiphase multicomponent fluid therethrough, the pressure of the fluid flow path being substantially the same as the pressure of an environment to be sampled; a sample capture chamber in direct fluid communication with the fluid flow path and having an inlet for receiving the high pressure multiphase multicomponent fluid therein and an outlet for expelling the high pressure multiphase multicomponent fluid therefrom; valves means configured to fluidly seal the inlet and outlet of the sample capture chamber and thereby capture the representative fluid sample of the multiphase multicomponent fluid as it passes therethrough; and control means for controlling the valve means so that the pressure of the representative fluid sample is substantially the same as the high pressure multiphase multicomponent fluid in the fluid flow path.
