Abstract

La présente invention concerne un procédé de traitement d'un courant d'hydrocarbures dans une usine, le procédé comprenant au moins les étapes consistant à : (a) introduire un courant d'alimentation partiellement condensé (10) dans un premier séparateur gaz/liquide (2); (b) séparer le courant d'alimentation (10) dans le premier séparateur gaz/liquide (2) en un courant gazeux (20) et un courant liquide (30); (c) dilater le courant liquide (30) obtenu à l'étape (b) et l'introduire (40) dans un deuxième séparateur gaz/liquide (3) en un premier point d'alimentation (31); (d) dilater le courant gazeux (20) obtenu à l'étape (b) pour obtenir ainsi un courant au moins partiellement condensé (50), puis l'introduire dans le deuxième séparateur gaz/liquide (3) en un deuxième point d'alimentation (32), le deuxième point d'alimentation (32) se situant à un niveau supérieur à celui du premier point d'alimentation (31); (e) introduire un courant de gaz naturel liquéfié (70, 70b) dans le deuxième séparateur gaz/liquide (3) en un troisième point d'alimentation (33) situé à un niveau supérieur à celui du deuxième point d'alimentation (32); (f) retirer par le sommet du deuxième séparateur gaz/liquide (3) un courant gazeux pauvre en C2+ (60); et (g) retirer par le fond du deuxième séparateur gaz/liquide (3) un courant liquide (80, 80a); dans lequel le courant de gaz naturel liquéfié (70, 70b) tel qu'introduit à l'étape (e) est obtenu à partir d'une source (4) de gaz naturel liquéfié d'une usine distincte.
