Yearly average gas quality

General picture

Please note that Energinet's yearly averages only provide a general picture. Though we consider the numbers to be accurate, not all of the information is generated by Energinet. Consequently, Energinet cannot attest to the accuracy of the figures, and has neither verified nor approved the information. Importantly, the data is not suited for calculating settlements of commercial transactions in the gas market.

2017 composition

The table shows the average gas composition for 2017, measured at Energinet’s gas quality metering station at Egtved.

 

 

No measurable heavy metals

Energinet monitors the presence of metals in the gas. Generally there are neither measurable amounts of heavy metals nor measurable amounts of alkali metals. Thoughs traces of arsenic were recorded in 2002, there were no detectable amounts in Energinet’s 2012 reading.

Analysis of hydrocarbon levels

Energinet regularly performs an analysis of heavy hydrocarbons in the natural gas. A 2012 analyses identified approx. 50 different hydrocarbons, mostly C6, C7, C8 and C9. For example, in Danish gas from the Northsea the profile of a C6+ content of 0,082 mol-% looks like this:
0,072 mol-% C6, 0,008 mol-% C7, 0,002 mol-% C8 and 0,0002 mol-% C9.
