In delivery to end users such as gas-fired power plants or energy companies that supply natural gas for home heating, the gas composition needs to be known to determine the calorific value of the natural gas.
Moreover, the natural gas composition in distribution networks needs to be monitored to ensure that it complies with legal gas composition standards. Local and near-real-time analysis allows for fast adjustment of the natural gas composition to meet legislation. This also applies to mixing plants for adding nitrogen to high-calorific natural gas, to convert it into low-calorific gas.
Injecting sustainably produced green hydrogen into natural gas streams provides another way to reduce greenhouse gas emissions. As the hydrogen concentration may vary over time, near-real-time monitoring of the gas composition of this natural gas/hydrogen blend is needed to determine its calorific value.
