Permanent gas analysis covers a wide range of applications in the petrochemical, chemical, and energy industry fields. For example, permanent gases such as O2, CO2, N2, Ar, CH4 or ethane are common in pure gas manufacturing, refinery gases, natural gas, fuel cell gases, and many other industrial processes.
Automatic identification and quantification of the concentration of these components can be important for the control of manufacturing processes and production quality. Chromatotec® has developed a method for the measurement of C1- C6+ in natural gas (H2S can be measured as an option).
The system uses N2 (produced by our Nitroxychrom Nitrogen generator) as its carrier gas and a thermal conductivity detector (TCD). To run the analytical system, only an electric supply is necessary. The analytical columns are manufactured at Chromatotec® and ensure the good and repeatable separation of the analytes.
The system operates in a manner which enables the detection of the analytes, while other possible interferents are not injected in the main column thanks to a timely commutation. It is available with a custom configuration for safe and hazardous areas : ATEX, IECEx, CSA and CSA international certifications for its application in refineries and petrochemical plants.
