Hydrocarbon gas sampling

Mechatest delivers operator safety and friendly Hydrocarbon gas sampling systems that allows for sampling in a safe and controlled environment. To take under high pressure Hydrocarbon gas samples the conventional way is not only inefficient, but in the case of this dangerous media, humans and the environment are subjected to high safety risks, the Mechatest Hydrocarbon gas samplers are the safe and efficient solution for Hydrocarbon gas sampling under high process pipeline pressure and temperature. The Mechatest Hydrocarbon gas sampling systems are based on gas cylinder sampling principle, a perfect solution for Hydrocarbon gas sampling from tanks, containers, pipeline and reactors, to take representative samples of Hydrocarbon gas in high pressure applications. 

The problem with some Hydrocarbon gas samples is that it can change state if the pressure varies. This requires a sample system and a sample cylinder with a safe outage tube. 

Hydrocarbons are a primary energy source for current civilizations. The predominant use of hydrocarbons is as a combustible fuel source. In their solid form, hydrocarbons take the form of asphalt (bitumen).


Mixtures of volatile hydrocarbons are now used in preference to the chlorofluorocarbons as a propellant for aerosol sprays, due to chlorofluorocarbons' impact on the ozone layer.

Methane (CH4) and ethane (C2H6) are gaseous at ambient temperatures and cannot be readily liquefied by pressure alone. Propane (C3H8) is however easily liquefied, and exists in 'propane bottles' mostly as a liquid. Butane (C4H10) is so easily liquefied that it provides a safe, volatile fuel for small pocket lighters.

Sampling of Hydrocarbon Gas in Sample Cylinder

The big advantage of the Hydrocarbon gas sampling system is the possibility to take Hydrocarbon gas sample under (high) process pressure and fill it into a sample cylinder, the sample is directly take from a tank, container, pipeline, reactors or mixer. We have improved our sampling systems for gas by:

  • Creating closed loop systems emission free which provide a safe, controlled environment
  • Suitable for high pressure process application
  • Simplifying designs, making the sampling of liquid and gas more efficient
  • Proper discharge of excess liquid or gas prevents unwanted pressure build-up in the system

These modern solutions simply regard the sampling systems themselves. Our worldwide reputation rests on the combination of excellent systems, and professional services by our team of specialists.
