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.
