Abstract

L'invention concerne un procédé pour l'élimination à long terme de diphényles chlorés (PCB) hors de liquides isolants de transformateurs lors du remplacement d'huiles de PCB par d'autres liquides isolants, en particulier, des huiles de silicones. On fait circuler continuellement le liquide isolant à travers une résine adsorbante pour l'huile de PCB et, lorsqu'elle a été chargée d'huile de PCB, par lavage avec un solvant pour les huiles de PCB, on en libère la résine adsorbante, tandis qu'avant sa réutilisation pour l'adsorption d'une huile de PCB, le résine adsorbante qui a été lavée avec la solvant, est libérée de ce dernier par balayage avec un gaz.
