Abstract

L'invention concerne un procédé de régénération d'un fluide halogéné usé dont la densité est supérieure à 9,0 lbs/gal (1,078 g/cm3)et contenant des impuretés à la fois solubles et insolubles. Ce procédé consiste (1) à ajouter de l'acide au fluide usé de manière que le pH soit approximativement compris entre 0 et 10 ; (2) à mettre en contact le fluide halogéné usé avec l'halogène afin d'augmenter la densité jusqu'à au moins 10 lbs/gal (1,198 g/cm3), à maintenir la véritable température de cristallisation désirée du fluide et à oxyder les impuretés solubles ; (3) à ajouter un agent réducteur tout en ajustant la température à une température minimale de 10 °C ; (4) à mettre en contact le fluide avec un alcali afin de neutraliser l'excès d'acide ; et (5) à séparer n'importe quelles impuretés suspendue solides du fluide.
