Abstract

Selon l'invention, un courant de gaz naturel liquéfié brut (108), dilaté (102) et refroidi (106) est séparé dans une colonne (150) de rejet d'azote en un courant de vapeur de tête enrichi en azote (130) et un courant de liquide de résidu à teneur diminuée en azote (110). Le courant de résidu (110) est pompé (112) à une pression supérieure, divisé en des premier et second courants (114 & 116), puis le second courant est réduit en pression et au moins partiellement vaporisé (118) par échange de chaleur (106) contre le courant (104) d'alimentation en GNL brut pour refroidir ledit courant d'alimentation et obtenir (120) un état d'ébullition à la colonne de rejet d'azote (150).
