Abstract

La présente invention concerne un procédé de purification d’une composition comprenant un hydrohalocarbure B comprenant les étapes de : i) fourniture d’une composition A1 comprenant un hydrohalocarbure B et au moins une impureté C différente dudit hydrohalocarbure B, ii) compression de ladite composition A1 et, éventuellement refroidissement de celle-ci, de sorte à obtenir ledit hydrohalocarbure B sous forme liquide pour former un flux A2 liquide comprenant ledit hydrohalocarbure B, iii) distillation dudit flux A2 obtenu à l’étape ii) pour former et récupérer un flux A3 comprenant ledit hydrohalocarbure B, caractérisé en ce que l’étape iii) est mise en œuvre dans un dispositif de distillation sous pression comprenant un ou plusieurs lit(s) à garnissage rotatif.
