Abstract

Il est décrit une méthode de décontamination efficace dune couche doxyde. Plus particulièrement, il est décrit une méthode servant à décontaminer une couche doxyde qui comprend les éléments suivants : a) fournir de leau de procédé de décontamination qui contient de lacide sulfurique (B2SO4), de lhydrazine (N2B4)et du sulfate de cuivre (CuSO4) à un circuit de pipeline en vue de décontaminer la couche doxyde du circuit de pipeline; b) mélanger du Ba(OH)2 à leau de procédé de décontamination obtenue par suite de la décontamination de la couche doxyde de létape a) en vue de modifier un pH de leau de procédé de décontamination jusquà ce quil se trouve entre 8,2 et 9,4, et ce, afin de réaliser une réaction de précipitation; c) procéder au filtrage de leau de procédé de décontamination obtenue par suite de la réaction de précipitation de létape b) afin déliminer une substance insoluble de leau de procédé de décontamination; d) réutiliser leau de procédé de décontamination en tant queau de procédé de décontamination pour létape a) par suite de lélimination de la substance insoluble réalisée à létape c).
