Gas quality tracking

 Gas quality tracking Interface

Natural gases of different origin may vary significantly in terms of their composition and hence their calorific value. The calorific value of bio natural gas, which is increasingly upgraded to meet natural gas quality specifications and fed into grids, is usually 5-10% lower than that of the natural gas supplied in a service area. The calorific value of hydrogen is even lower by a factor of 3 (per cubic meter). The equipment installed on the gas customer’s premises normally only measures the gas volume, so how then can the energy content of the gas be determined correctly?

The billing of gas and the actual energy supplied is governed by various codes and standards. In Germany it is DVGW Code of Practise G685 which states that where several gases are fed into a pipeline system, the difference between their superior calorific values must not exceed 2%. If this limit cannot be met, then previously the network operator had no option but to measure the superior calorific value at each exit point, or to condition the gas supplied; in the case of bio natural gas, this was usually done by adding liquefied petroleum gas (propane). Both options come with significant costs for the network operator.

SmartSim offers a simple and efficient way of determining the superior calorific values needed for gas billing at exit points using gas quality tracking.
