Natural gas is a fossil fuel. Like other fossil fuels such as coal and oil, natural gas forms from the plants, animals, and microorganisms that lived millions of years ago. There are several different theories to explain how fossil fuels are formed. The most prevalent theory is that they form underground, under intense conditions.

As a result, different types of natural gas are used in the EU, rather than one type of gas with one specific quality. This can cause problems in an integrated energy market, as suppliers in one country risk having their gas rejected by transmission system operators in another because the gas does not have the right quality.

Natural gas quality upgrade processes. In a gas processing facility, the produced natural gas is upgraded from its well composition (see Fig. 1) to the required specification by a sequence of processes as indicated in Fig. 2; these processes are conducted in a typical series starting by phase separation followed by mercury removal, …

implies excellence or superiority. However, when speaking in the context of "natural gas quality," the word "quality" simply means any of the features that describe the chemical or physical characteristics of natural gas. The subject of natural gas quality has received a great deal of attention by all industry sectors, from the

The Gas Quality focus area will consider how market rules may need to evolve to accommodate more diverse, low carbon gases into the GB gas system. ... how blending hydrogen with natural gas in the existing gas infrastructure can support the transition to a net zero future. The project has created two timelines to map out how the existing gas ...

These reference gases are the replacement for the prior standards maintained by the U.S. National Institute of Standards and Technology. The natural gas standards are intended to serve as the primary carbon …

How we determine gas quality. Natural gas is made up of several component gases and is therefore subject to natural variation. We use the Wobbe Number/Index to measure the energy of gas within a given volume, rather than calorific value (CV) which is subject to natural variation. This inconsistency affects the energy contained within a given ...
