Abstract
1 degrés Procédé permettant d'abaisser, à moins de 100 vpm, la teneur en oxydes d'azote des gaz de queue, sans addition d'air de dilution, et consistant à terminer l'absorption à une température réduite. 2 degrés Modes de mise en oeuvre du procédé ci-dessus, caractérisés par les points suivants, séparément ou en combinaisons : a. La teneur en oxygène dans les gaz de queue est au moins de 2 %. b. La température de fin d'absorption doit être inférieure à 10 degrés C, de preférence 4 degrés C. c. Le nombre de plateaux est très limité. d. Les besoins en énergie sont relativement peu importants.
