Explosion-proof process gas chromatograph is designed for the continuous automatic measurement of the mole fraction of combustible natural gas (CNG) components in accordance with GOST 31371.7-2008 (ISO 6974), Methods A and B, followed by calculation of the component values of the composition variables of the calorific value, relative and absolute density, compressibility factor and Wobbe index under GOST 31369-2008 (ISO 6976).
Process gas chromatograph MAG for natural gas analysis system can be used in commercial accounting and monitoring gas quality at the gas metering and gas distribution stations, automatic control systems and process control refineries, petrochemical, and other gas processing plants.
- Backflush of C6 + 5 min;
- Flow rate of carrier gas is up to 12 ml / min;
- Additionally, for natural gas it is possible to analyze:
- Helium and hydrogen;
- Extended hydrocarbon composition with the hydrocarbon dew point calculation.
- Analysis of natural gas of variable and extended (by certified measurement methods).
Measurement ranges and the absolute values of the extended uncertainty of measurement results in the mole fraction of the components correspond to GOST GGP 31371.7-2008 "Natural gas. Determination of composition with defined uncertainty by gas chromatography method. Part 7. Measurement procedure of the mole fraction of components"
Option: can be manufactured in a laboratory based design.
