Abstract

Procédé pour doser le carbone contenu dans de l'eau sous la forme de composés organiques. Dans une première étape on injecte dans le réacteur 2, de l'eau par 1 et de l'air par 3, le rapport volumique de l'oxygène à la vapeur d'eau ne devant pas dépasser 5 %. Il règne dans ce réacteur une température de 900 degrés C. Le gaz effluent est envoyé au photomètre à infrarouge 4 où se fait le dosage de CO2 . Dans une seconde étape on opère de la même façon mais sans injecter d'air. Par différence entre les valeurs obtenues on obtient la grandeur cherchée. Application au dosage des hydrocarbures dans les eaux usées.
