Title (EN) PROCESSES AND SYSTEMS FOR SEPARATING CARBON DIOXIDE IN THE PRODUCTION OF ALKANES
(FR) PROCÉDÉS ET SYSTÈMES DE SÉPARATION DE DIOXYDE DE CARBONE DANS LA PRODUCTION D'ALCANES
Abstract:
(EN) A method for separating CO2 from C2 to C5 alkanes includes introducing a first stream including C2 to C5 alkanes and CO2 into a first separation zone, the first separation zone including a hydrocarbon solvent, and separating the first stream into a recycle stream and a second stream in the first separation zone. The recycle stream including CO2 and one or more of CO, H2, and CH4, and the second stream including C2 to C5 alkanes. The method further includes introducing the second stream into a second separation zone, and separating the second stream into a third stream and a fourth stream, wherein the third stream includes C2 alkanes and the fourth stream includes C3 to C5 alkanes.
(FR) L’invention concerne un procédé de séparation de CO2 de C2 à C5 alcanes comprenant l'introduction d'un premier courant comprenant des alcanes en C2 à C5 et du CO2 dans une première zone de séparation, la première zone de séparation comprenant un solvant hydrocarboné, et la séparation du premier flux en un flux de recyclage et un second flux dans la première zone de séparation. Le flux de recyclage comprenant du CO2 et un ou plusieurs CO, H2, et CH4, et le second flux comprenant des alcanes en C2 à C5. Le procédé comprend en outre l'introduction du second flux dans une seconde zone de séparation, et la séparation du second flux en un troisième flux et un quatrième flux, le troisième flux comprenant des alcanes en C2 et le quatrième flux comprenant des alcanes en C3 à C5.
