Abstract

La présente invention a pour objet un procédé de purification et de séparation d'un mélange de gaz renfermant plusieurs composants à points d'ébullition différents, dans lequel le mélange de gaz est conduit à travers des lits de purification et d'adsorption disposés en série où il est soumis à des variations de pression et où l'adsorption se produit à une pression relativement élevée, cependant que la désorption se produit à une pression relativement basse. Ce procédé est caractérisé en ce que l'établissement de la pression requise pour l'adsorption, après la désorption, est effectué au moins à concurrence de 20 % par introduction, entre le lit de purification et le lit d'adsorption, d'un gaz constitué par le(s) composant(s) à point d'ébullition réduit. Elle ce rapporte au domaine de la séparation, à l'état pur, d'un composant à partir d'un mélange gazeux.
