Abstract

Procédé permettant de fractionner un gaz où - on refroidit le gaz de T0 à une température T1, - on envoie au moins une partie de la phase gazeuse G1 à une étape de détente (X1) de manière à obtenir une phase mixte M2 à une température T2 et une pression P2, - on envoie la phase mixte M2 à une étape d'échange de chaleur où elle joue le rôle d'agent de réfrigération, et à l'issue de laquelle elle est réchauffée, - on envoie la phase liquide L1 à une étape de détente, - on envoie la phase mixte réchauffée et la phase liquide détendue à une étape de séparation pour obtenir une phase gazeuse et une phase liquide, et - on fractionne la phase gazeuse par distillation réalisée à l'aide d'un échange de chaleur continue avec la phase mixte M2 et, on extrait les constituants dits légers sous forme de gaz et les constituants lourds sous forme de condensats, l'étape de fractionnement étant réalisée après l'étape de détente de la phase mixte M2.
