Abstract

Le but de la présente divulgation est de fournir un nouveau procédé de séparation pour séparer un gaz frigorigène.　Ce procédé de séparation de gaz comprend : une première étape dans laquelle un gaz de matière première contenant au moins un gaz réfrigérant A et un gaz réfrigérant B est fourni à un premier module pour obtenir un premier gaz de séparation et un premier gaz de maintien qui diffèrent en termes de composition du gaz de matière première ; et une seconde étape dans laquelle le premier gaz de séparation est fourni à un second module pour obtenir un second gaz de séparation et un second gaz de maintien qui diffèrent en termes de composition du premier gaz de séparation. Le premier module et/ou le second module comprennent une membrane de tamis moléculaire.
