(FR) PROCEDE POUR DETERMINER LA QUALITE D'UN GAZ
Abstract
(DE)
Die Erfindung betrifft Verfahren zur Ermittlung vornehmlich der Kompressibilitätszahl K, des volumetrischen Normbrennwertes Hv,n und der Normdichte $g(r)n von Probengasen (1) anhand ermittelter Werte aus einem Spektrum der Probengase (1). Hierbei werden verschiedene Ansätze vorgeschlagen, mittels zweistufiger Iterationsverfahren die zur Bestimmung der gesuchten Werte benötigten Größen anhand der Daten des Spektrums im Betriebszustand auf den Normzustand umzuwerten, ohne aufwendige Behandlungen des Probengases (1) vornehmen zu müssen. Ebenfalls werden Vorrichtungen vorgeschlagen, die insbesondere auch zur Bestimmung der in den Verfahren benötigten Größen nutzbar sind und bekannte hierzu nutzbare Einrichtungen weiterentwickeln.
(EN)
The invention relates to a method of determining mainly the compressibility number K, the standard volumetric gross calorific value Hv,n and the standard density $g(r)n of test gases (1) using values determined from a spectrum of the test gases (1). 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 (1) to time-consuming treatments. The invention further relates to devices which are useful for determining the values required for said methods and which further develop devices that can be used for carrying out said methods.
(FR)
L'invention concerne un procédé permettant de déterminer principalement le coefficient de compressibilité K, le pouvoir calorifique standard volumétrique Hv,n et la densité standard $g(r)n de gaz d'échantillonnage (1) sur la base de valeurs dérivées d'un spectre des gaz d'échantillonnage (1). A cet effet, il est prévu plusieurs méthodes pour convertir les grandeurs requises pour déterminer les valeurs voulues, sur la base des données du spectre à l'état de marche, aux conditions normales, à l'aide d'un procédé d'itération à deux étapes, sans avoir à traiter le gaz d'échantillonnage (1) de manière complexe. L'invention concerne en outre des dispositifs s'utilisant également pour déterminer les grandeurs requises dans le procédé et pour perfectionner des dispositifs connus pouvant également s'utiliser dans ce contexte.
