Abstract

La présente invention a trait à un procédé de détection photo-acoustique pour mesurer la concentration d'un composant non hydrocarboné d'un mélange gazeux contenant du méthane. Le procédé est essentiellement caractérisé en ce que le spectre d'absorption photo-acoustique pour le mélange gazeux est enregistré sur une gamme de longueurs d'ondes sélectionnées pendant que le mélange gazeux circule en continu à travers l'appareil de mesure, et ensuite pour la détermination de la concentration du composant non hydrocarboné le spectre ainsi obtenu est utilisé en combinaison avec un signal photo-acoustique généré par une cellule de référence (3) remplie d'un gaz ayant des propriétés prédéterminées. Le mélange gazeux contenant du méthane et le composant non hydrocarboné sont, de préférence, choisis pour constituer du gaz naturel destiné à être évacués vers des conduits de gaz et de vapeur d'eau, respectivement. L'invention permet ainsi une détection à haute précision, même dans des conditions industrielles, de la teneur en vapeur d'eau présente dans des concentrations aussi faibles qu'environ 0,5 ppm dans du gaz naturel.The present invention relates to a photo-acoustic detection method for measuring the concentration of a non-hydrocarbon component of a gas mixture containing methane. The method is essentially characterized in that the photoacoustic absorption spectrum for the gas mixture is recorded over a range of selected wavelengths while the gas mixture flows continuously through the measuring device, and then for the determination of the concentration of the non-hydrocarbon component the spectrum thus obtained is used in combination with a photo-acoustic signal generated by a reference cell (3) filled with a gas having predetermined properties. The methane-containing gas mixture and the non-hydrocarbon component are preferably chosen to constitute natural gas intended to be evacuated to gas and steam conduits, respectively. The invention thus allows high precision detection, even under industrial conditions, of the water vapor content present in concentrations as low as about 0.5 ppm in natural gas.
