Process for removing oxygen dissolved in water

a. The process is intended to remove oxygen contained in water in order to ensure protection against corrosion in water boilers and in preserving components withdrawn from service from moisture. b. In order to improve the activity of hydrazine, cationic or anionic complexes of trivalent cobalt with inorganic ligands or mixtures of these products are added to its solution. c. The hydrazine solutions containing these activating agents are suitable to this end on water where they show a high reaction rate, but also for removing gaseous oxygen. . A.LE PROCEDE EST DESTINE A ELIMINER L'OXYGENE CONTENU DANS L'EAU POUR ASSURER LA PROTECTION CONTRE LA CORROSION DANS LES CHAUDIERES A EAU ET DANS LA CONSERVATION A L'HUMIDITE DE PIECES RETIREES DU SERVICE.B.POUR AMELIORER L'ACTIVITE DE L'HYDRAZINE, ON AJOUTE A SA SOLUTION DES COMPLEXES CATIONIQUES OU ANIONIQUES DU COBALT TRIVALENT AVEC DES LIGANDS MINERAUX OU DES MELANGES DE CES PRODUITS.C.LES SOLUTIONS D'HYDRAZINE CONTENANT CES ACTIVATEURS CONVIENNENT A CET EFFET SUR L'EAU OU ELLES FONT PREUVE D'UNE GRANDE VITESSE DE REACTION, MAIS AUSSI POUR ELIMINER L'OXYGENE DE GAZ.
