Abstract

Ce procédé comprend les étapes suivantes :(a) on introduit le gaz naturel de départ (101) dans une première colonne de distillation (31) qui produit en tête un gaz naturel pré-traité (111), lequel gaz naturel pré-traité (111) ne contient pratiquement plus d'hydrocarbures en C6+ ; (b) on introduit le gaz naturel pré-traité (111) dans une unité (19) de récupération des LGN comprenant au moins une deuxième colonne de distillation (49), de façon à produire, d'une part, en tête de colonne, un gaz naturel purifié (151), et d'autre part, une coupe de LGN (15) ; et (c) on forme ledit gaz naturel apte à être liquéfié (161) à partir du gaz naturel purifié (151) issu de l'étape (b) .
