ABSTRACT:
The invention relates to a method of determining mainly the compressibility number K, the standard volumetric gross calorific value Hv,nand the standard density ρnof test gases using values determined from a spectrum of the test gases. The invention describes various approaches of translating the values for determining the desired values using the data of the spectrum in the operational condition to the standard reference condition using two-step iteration processes without having to subject the test gases to time-consuming treatments. The invention further relates to devices for determining the values required for the methods and which further develop devices for carrying out the methods.
