Abstract

L'invention concerne un procédé de purification d'un polyéthylène recyclé. Le procédé comprend l'obtention de polyéthylène recyclé, sa mise en contact avec un premier solvant fluide pour produire un polyéthylène recyclé extrait, puis la dissolution du polyéthylène recyclé extrait dans un solvant pour produire une première solution comprenant du polyéthylène et des contaminants en suspension. La première solution est décantée pour produire une deuxième solution comprenant du polyéthylène et des contaminants restants. La deuxième solution est purifiée par mise en contact de la deuxième solution avec un milieu solide pour produire une troisième solution comprenant du polyéthylène plus pur. Enfin, le polyéthylène plus pur est séparé de la troisième solution.
