Natural Gas Monitoring 

Selective measurement in complex gas mixtures 

The analysis of natural gas has recently become increasingly important. Since energy flows currently come from a variety of sources, this has significant implications for gas quality. Known sources include regional supply sources, injection of biogas and hydrogen from renewable sources, and the increasing use of LNG.

By knowing the gas flows and calorific values, this distribution in the network can be calculated or simulated. This SmartSim software enables grid operators to bill correctly for the injection of different gas qualities and thus simplifies the injection of biogas and hydrogen. Within the framework of a research project, these calculations are to be supported by reliable gas monitors.

For this purpose, Wi.Tec supplies a gas monitor (NGA) that can selectively detect methane (80 – 100 Vol.%) and CₙHₘ (0 – 10 Vol.%). Furthermore, the CO₂ concentration (0 – 5 Vol.%) in the natural gas mixture is analyzed. The gas analysis is performed with a 3-channel INFRA.sens® and provides long-term stable measurement results.
