Beschreibung
Zusammenfassung:	The invention relates to a method for the treatment of natural gas containing carbon dioxide, methane and paraffins, said method comprising: a step of extracting the paraffins from the natural gas in a paraffin-removal column, and a step of separating the carbon dioxide and the methane in a distillation column, the operation of the two columns being provided by means of the thermal coupling of said two columns using a thermal coupling heat exchanger. L'invention concerne un procédé de traitement d'un gaz naturel comprenant du dioxyde de carbone, du méthane et des paraffines, comprenant une étape d'extraction des paraffines du gaz naturel dans une colonne de déparaffinage et une étape de séparation du dioxyde de carbone et du méthane dans une colonne à distiller, le fonctionnement des deux colonnes étant assuré par un couplage thermique de ces deux même colonnes à l'aide d'un échangeur de chaleur de couplage thermique.
