Abstract

Procédé de production simultanée de gaz naturel traité et d'un courant riche en propane à partir d'un gaz d'alimentation, comprenant les étapes suivantes : Etape a) : on condense partiellement le gaz d'alimentation ; Etape b) : on sépare le gaz issu de l'étape a) en un premier courant liquide et un premier courant gazeux ; Etape c) : on détend au moins une partie du premier courant gazeux issu de l'étape b) ; Etape d) : on introduit le gaz issu de l'étape c) dans une première colonne à distiller ; caractérisé en ce qu'il comporte l'une ou l'autre des étapes suivantes: Etape f) : pour obtenir des taux d'extraction d'éthane supérieurs à un premier seuil, on condense partiellement au moins une partie dudit premier courant gazeux issu de l'étape b) et on l'introduit dans pot séparateur de phases afin de produire un deuxième courant gazeux et un deuxième courant liquide, au moins une partie dudit deuxième courant gazeux est condensée et introduite dans ladite première colonne à distiller ; - Etape g) : pour obtenir des taux d'extraction d'éthane inférieurs à un deuxième seuil, on récupère une coupe gazeuse en tête de ladite deuxième colonne à distiller, puis on la condense avant de l'introduire dans ladite première colonne à distiller.
