This International Standard specifies methods for the calculation of compression factors of natural gases, natural
gases containing a synthetic admixture and similar mixtures at conditions under which the mixture can exist only as
a gas.
This part of ISO 12213 specifies a method for the calculation of compression factors when the superior calorific
value, relative density and carbon dioxide content are known, together with the relevant pressures and
temperatures. If hydrogen is present, as is often the case for gases with a synthetic admixture, the hydrogen
content also needs to be known.
NOTE In principle, it is possible to calculate the compression factor when any three of the parameters superior calorific
value, relative density, carbon dioxide content (the usual three) and nitrogen content are known, but subsets including nitrogen
content are not recommended.
The method is primarily applicable to pipeline quality gases within the ranges of pressure p and temperature T at
which transmission and distribution operations normally take place, with an uncertainty of about ± 0,1 %. For widerranging
applications the uncertainty of the results increases (see annex E).
More detail concerning the scope and field of application of the method is given in part 1 of this International
Standard.
