Abstract

L'invention concerne des procédés et des appareils permettant d'extraire de l'azote présent dans des alimentations en gaz naturel liquéfié. Les procédés comprennent les étapes consistant : (i) à refroidir l'alimentation et faire passer l'alimentation dans une colonne de fractionnement ; (ii) à retirer de la colonne de fractionnement un courant de vapeur de tête ayant une teneur en azote enrichie, et un courant de liquide ayant une teneur en azote réduite ; (iii) à diviser le courant de vapeur de tête provenant de l'étape (ii) en au moins des premier et second courants de tête ; (iv) à comprimer, refroidir et au moins partiellement condenser au moins le premier courant de tête provenant de l'étape (iii) ; et (v) à détendre le courant provenant de l'étape (iv) et faire passer le courant détendu dans la colonne de fractionnement en tant que reflux. Un refroidissement est prévu à l'étape (iv), au moins en partie, par échange de chaleur avec un ou plusieurs courants provenant de la colonne de fractionnement.
